By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

Supported backends + + - **graphite** (`plaintext interface`, used by **Graphite**, **InfluxDB**, **KairosDB**, + **Blueflood**, **ElasticSearch** via logstash tcp input and the graphite codec, etc) + + metrics are sent to the backend server as `prefix.hostname.chart.dimension`. `prefix` is + configured below, `hostname` is the hostname of the machine (can also be configured). + + - **opentsdb** (`telnet interface`, used by **OpenTSDB**, **InfluxDB**, **KairosDB**, etc) + + metrics are sent to opentsdb as `prefix.chart.dimension` with tag `host=hostname`. + + - **json** document DBs + + metrics are sent to a document db, `JSON` formatted. + + - **prometheus** is described at [prometheus page](prometheus/) since it pulls data from netdata. + +2. Only one backend may be active at a time. + +3. Netdata can filter metrics (at the chart level), to send only a subset of the collected metrics. + +4. Three modes of operation (for all backends): + + - `as collected`: the latest collected value is sent to the backend. This means that if netdata + is configured to send data to the backend every 10 seconds, only 1 out of 10 values will appear + at the backend server. The values are sent exactly as collected, before any multipliers or + dividers applied and before any interpolation. This mode emulates other data collectors, + such as `collectd` or `telegraf`. + + - `average`: the average of the interpolated values shown on the netdata graphs is sent to the + backend. So, if netdata is configured to send data to the backend server every 10 seconds, + the average of the 10 values shown on the netdata charts will be used. **If you can't decide + which mode to use, use `average`.** + + - `sum` or `volume`: the sum of the interpolated values shown on the netdata graphs is sent to + the backend. So, if netdata is configured to send data to the backend every 10 seconds, the + sum of the 10 values shown on the netdata charts will be used. + +5. This code is smart enough, not to slow down netdata, independently of the speed of the backend server. + +## configuration + +In `/etc/netdata/netdata.conf` you should have something like this (if not download the latest version +of `netdata.conf` from your netdata): + +``` +[backend] + enabled = yes | no + type = graphite | opentsdb | json + host tags = list of TAG=VALUE + destination = space separated list of [PROTOCOL:]HOST[:PORT] - the first working will be used + data source = average | sum | as collected + prefix = netdata + hostname = my-name + update every = 10 + buffer on failures = 10 + timeout ms = 20000 + send charts matching = * + send hosts matching = localhost * + send names instead of ids = yes +``` + +- `enabled = yes | no`, enables or disables sending data to a backend + +- `type = graphite | opentsdb | json`, selects the backend type + +- `destination = host1 host2 host3 ...`, accepts **a space separated list** of hostnames, + IPs (IPv4 and IPv6) and ports to connect to. + Netdata will use the **first available** to send the metrics. + + The format of each item in this list, is: `[PROTOCOL:]IP[:PORT]`. + + `PROTOCOL` can be `udp` or `tcp`. `tcp` is the default and only supported by the current backends. + + `IP` can be `XX.XX.XX.XX` (IPv4), or `[XX:XX...XX:XX]` (IPv6). + For IPv6 you can to enclose the IP in `[]` to separate it from the port. + + `PORT` can be a number of a service name.

This allows + you to load-balance different servers: give your backend servers in different order on each netdata. + + netdata also ships [`nc-backend.sh`](nc-backend.sh), + a script that can be used as a fallback backend to save the metrics to disk and push them to the + time-series database when it becomes available again. It can also be used to monitor / trace / debug + the metrics netdata generates. + +- `data source = as collected`, or `data source = average`, or `data source = sum`, selects the kind of + data that will be sent to the backend. + +- `hostname = my-name`, is the hostname to be used for sending data to the backend server. By default + this is `[global].hostname`. + +- `prefix = netdata`, is the prefix to add to all metrics. + +- `update every = 10`, is the number of seconds between sending data to the backend. netdata will add + some randomness to this number, to prevent stressing the backend server when many netdata servers send + data to the same backend. This randomness does not affect the quality of the data, only the time they + are sent. + +- `buffer on failures = 10`, is the number of iterations (each iteration is `[backend].update every` seconds) + to buffer data, when the backend is not available. If the backend fails to receive the data after that + many failures, data loss on the backend is expected (netdata will also log it). + +- `timeout ms = 20000`, is the timeout in milliseconds to wait for the backend server to process the data. + By default this is `2 * update_every * 1000`. + +- `send hosts matching = localhost *` includes one or more space separated patterns, using ` * ` as wildcard + (any number of times within each pattern). The patterns are checked against the hostname (the localhost + is always checked as `localhost`), allowing us to filter which hosts will be sent to the backend when + this netdata is a central netdata aggregating multiple hosts. A pattern starting with ` ! ` gives a + negative match. So to match all hosts named `*db*` except hosts containing `*slave*`, use + `!*slave* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive + or negative). + +- `send charts matching = *` includes one or more space separated patterns, using ` * ` as wildcard (any + number of times within each pattern). The patterns are checked against both chart id and chart name. + A pattern starting with ` ! ` gives a negative match. So to match all charts named `apps.*` + except charts ending in `*reads`, use `!*reads apps.*` (so, the order is important: the first pattern + matching the chart id or the chart name will be used - positive or negative). + +- `send names instead of ids = yes | no` controls the metric names netdata should send to backend. + netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read + by the system and names are human friendly labels (also unique). Most charts and metrics have the same + ID and name, but in several cases they are different: disks with device-mapper, interrupts, QoS classes, + statsd synthetic charts, etc. + +- `host tags = list of TAG=VALUE` defines tags that should be appended on all metrics for the given host. + These are currently only sent to opentsdb and prometheus. Please use the appropriate format for each + time-series db. For example opentsdb likes them like `TAG1=VALUE1 TAG2=VALUE2`, but prometheus like + `tag1="value1",tag2="value2"`. Host tags are mirrored with database replication (streaming of metrics + between netdata servers). + +## monitoring operation + +netdata provides 5 charts: + +1. **Buffered metrics**, the number of metrics netdata added to the buffer for dispatching them to the + backend server. + +2. **Buffered data size**, the amount of data (in KB) netdata added the buffer. + +3. ~~**Backend latency**, the time the backend server needed to process the data netdata sent. + If there was a re-connection involved, this includes the connection time.~~ + (this chart has been removed, because it only measures the time netdata needs to give the data + to the O/S - since the backend servers do not ack the reception, netdata does not have any means + to measure this properly). + +4. **Backend operations**, the number of operations performed by netdata. + +5. **Backend thread CPU usage**, the CPU resources consumed by the netdata thread, that is responsible + for sending the metrics to the backend server. + +![image](https://cloud.githubusercontent.com/assets/2662304/20463536/eb196084-af3d-11e6-8ee5-ddbd3b4d8449.png) + +## alarms + +The latest version of the alarms configuration for monitoring the backend is [here](../health/health.d/backend.conf) + +netdata adds 4 alarms: + +1. `backend_last_buffering`, number of seconds since the last successful buffering of backend data +2. `backend_metrics_sent`, percentage of metrics sent to the backend server +3. `backend_metrics_lost`, number of metrics lost due to repeating failures to contact the backend server +4. ~~`backend_slow`, the percentage of time between iterations needed by the backend time to process the data sent by netdata~~ (this was misleading and has been removed). + +![image](https://cloud.githubusercontent.com/assets/2662304/20463779/a46ed1c2-af43-11e6-91a5-07ca4533cac3.png) + diff --git a/backends/backends.c b/backends/backends.c new file mode 100644 index 000000000..53a9a2395 --- /dev/null +++ b/backends/backends.c @@ -0,0 +1,662 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#define BACKENDS_INTERNALS +#include "backends.h" + +// ---------------------------------------------------------------------------- +// How backends work in netdata: +// +// 1.

The new format allows easier queries for metrics and supports both `as collected` and normalized metrics. + +Before explaining the changes, we have to understand the key differences between netdata and prometheus. + +### understanding netdata metrics + +##### charts + +Each chart in netdata has several properties (common to all its metrics): + +- `chart_id` - uniquely identifies a chart. + +- `chart_name` - a more human friendly name for `chart_id`, also unique. + +- `context` - this is the template of the chart. All disk I/O charts have the same context, all mysql requests charts have the same context, etc. This is used for alarm templates to match all the charts they should be attached to. + +- `family` groups a set of charts together. It is used as the submenu of the dashboard. + +- `units` is the units for all the metrics attached to the chart. + +##### dimensions + +Then each netdata chart contains metrics called `dimensions`. All the dimensions of a chart have the same units of measurement, and are contextually in the same category (ie. the metrics for disk bandwidth are `read` and `write` and they are both in the same chart). + +### netdata data source + +netdata can send metrics to prometheus from 3 data sources: + +- `as collected` or `raw` - this data source sends the metrics to prometheus as they are collected. No conversion is done by netdata. The latest value for each metric is just given to prometheus. This is the most preferred method by prometheus, but it is also the harder to work with. To work with this data source, you will need to understand how to get meaningful values out of them. + + The format of the metrics is: `CONTEXT{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. + + If the metric is a counter (`incremental` in netdata lingo), `_total` is appended the context. + + Unlike prometheus, netdata allows each dimension of a chart to have a different algorithm and conversion constants (`multiplier` and `divisor`). In this case, that the dimensions of a charts are heterogeneous, netdata will use this format: `CONTEXT_DIMENSION{chart="CHART",family="FAMILY"}` + +- `average` - this data source uses the netdata database to send the metrics to prometheus as they are presented on the netdata dashboard. So, all the metrics are sent as gauges, at the units they are presented in the netdata dashboard charts. This is the easiest to work with. + + The format of the metrics is: `CONTEXT_UNITS_average{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. + + When this source is used, netdata keeps track of the last access time for each prometheus server fetching the metrics. This last access time is used at the subsequent queries of the same prometheus server to identify the time-frame the `average` will be calculated. So, no matter how frequently prometheus scrapes netdata, it will get all the database data. To identify each prometheus server, netdata uses by default the IP of the client fetching the metrics. If there are multiple prometheus servers fetching data from the same netdata, using the same IP, each prometheus server can append `server=NAME` to the URL. Netdata will use this `NAME` to uniquely identify the prometheus server. + +- `sum` or `volume`, is like `average` but instead of averaging the values, it sums them. + + The format of the metrics is: `CONTEXT_UNITS_sum{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. + All the other operations are the same with `average`. + +Keep in mind that early versions of netdata were sending the metrics as: `CHART_DIMENSION{}`. + + +### Querying Metrics + +Fetch with your web browser this URL: + +`http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes` + +*(replace `your.netdata.ip` with the ip or hostname of your netdata server)* + +netdata will respond with all the metrics it sends to prometheus. + +If you search that page for `"system.cpu"` you will find all the metrics netdata is exporting to prometheus for this chart. `system.cpu` is the chart name on the netdata dashboard (on the netdata dashboard all charts have a text heading such as : `Total CPU utilization (system.cpu)`.

Patterns starting with ` ! ` give a negative match (e.g `!*.bad users.* groups.*` will send all the users and groups except `bad` user and `bad` group). The order is important: the first match (positive or negative) left to right, is used. + +### Changing the prefix of netdata metrics + +netdata sends all metrics prefixed with `netdata_`. You can change this in `netdata.conf`, like this: + +``` +[backend] + prefix = netdata +``` + +It can also be changed from the URL, by appending `&prefix=netdata`. + +### accuracy of `average` and `sum` data sources + +When the data source is set to `average` or `sum`, netdata remembers the last access of each client accessing prometheus metrics and uses this last access time to respond with the `average` or `sum` of all the entries in the database since that. This means that prometheus servers are not losing data when they access netdata with data source = `average` or `sum`. + +To uniquely identify each prometheus server, netdata uses the IP of the client accessing the metrics. If however the IP is not good enough for identifying a single prometheus server (e.g. when prometheus servers are accessing netdata through a web proxy, or when multiple prometheus servers are NATed to a single IP), each prometheus may append `&server=NAME` to the URL. This `NAME` is used by netdata to uniquely identify each prometheus server and keep track of its last access time. diff --git a/backends/prometheus/backend_prometheus.c b/backends/prometheus/backend_prometheus.c new file mode 100644 index 000000000..223b3f9f0 --- /dev/null +++ b/backends/prometheus/backend_prometheus.c @@ -0,0 +1,566 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#define BACKENDS_INTERNALS +#include "backend_prometheus.h" + +// ---------------------------------------------------------------------------- +// PROMETHEUS +// /api/v1/allmetrics?format=prometheus and /api/v1/allmetrics?format=prometheus_all_hosts + +static struct prometheus_server { + const char *server; + uint32_t hash; + RRDHOST *host; + time_t last_access; + struct prometheus_server *next; +} *prometheus_server_root = NULL; + +static inline time_t prometheus_server_last_access(const char *server, RRDHOST *host, time_t now) { + static netdata_mutex_t prometheus_server_root_mutex = NETDATA_MUTEX_INITIALIZER; + + uint32_t hash = simple_hash(server); + + netdata_mutex_lock(&prometheus_server_root_mutex); + + struct prometheus_server *ps; + for(ps = prometheus_server_root; ps ;ps = ps->next) { + if (host == ps->host && hash == ps->hash && !strcmp(server, ps->server)) { + time_t last = ps->last_access; + ps->last_access = now; + netdata_mutex_unlock(&prometheus_server_root_mutex); + return last; + } + } + + ps = callocz(1, sizeof(struct prometheus_server)); + ps->server = strdupz(server); + ps->hash = hash; + ps->host = host; + ps->last_access = now; + ps->next = prometheus_server_root; + prometheus_server_root = ps; + + netdata_mutex_unlock(&prometheus_server_root_mutex); + return 0; +} + +static inline size_t prometheus_name_copy(char *d, const char *s, size_t usable) { + size_t n; + + for(n = 0; *s && n < usable ; d++, s++, n++) { + register char c = *s; + + if(!isalnum(c)) *d = '_'; + else *d = c; + } + *d = '\0'; + + return n; +} + +static inline size_t prometheus_label_copy(char *d, const char *s, size_t usable) { + size_t n; + + // make sure we can escape one character without overflowing the buffer + usable--; + + for(n = 0; *s && n < usable ; d++, s++, n++) { + register char c = *s; + + if(unlikely(c == '"' || c == '\\' || c == '\n')) { + *d++ = '\\'; + n++; + } + *d = c; + } + *d = '\0'; + + return n; +} + +static inline char *prometheus_units_copy(char *d, const char *s, size_t usable) { + const char *sorig = s; + char *ret = d; + size_t n; + + *d++ = '_'; + for(n = 1; *s && n < usable ; d++, s++, n++) { + register char c = *s; + + if(!isalnum(c)) *d = '_'; + else *d = c; + } + + if(n == 2 && sorig[0] == '%') { + n = 0; + d = ret; + s = "_percent"; + for( ; *s && n < usable ; n++) *d++ = *s++; + } + else if(n > 3 && sorig[n-3] == '/' && sorig[n-2] == 's') { + n = n - 2; + d -= 2; + s = "_persec"; + for( ; *s && n < usable ; n++) *d++ = *s++; + } + + *d = '\0'; + + return ret; +} + + +#define PROMETHEUS_ELEMENT_MAX 256 +#define PROMETHEUS_LABELS_MAX 1024 +#define PROMETHEUS_VARIABLE_MAX 256 + +struct host_variables_callback_options { + RRDHOST *host; + BUFFER *wb; + BACKEND_OPTIONS backend_options; + PROMETHEUS_OUTPUT_OPTIONS output_options; + const char *prefix; + const char *labels; + time_t now; + int host_header_printed; + char name[PROMETHEUS_VARIABLE_MAX+1]; +}; + +static int print_host_variables(RRDVAR *rv, void *data) { + struct host_variables_callback_options *opts = data; + + if(rv->options & (RRDVAR_OPTION_CUSTOM_HOST_VAR|RRDVAR_OPTION_CUSTOM_CHART_VAR)) { + if(!opts->host_header_printed) { + opts->host_header_printed = 1; + + if(opts->output_options & PROMETHEUS_OUTPUT_HELP) { + buffer_sprintf(opts->wb, "\n# COMMENT global host and chart variables\n"); + } + } + + calculated_number value = rrdvar2number(rv); + if(isnan(value) || isinf(value)) { + if(opts->output_options & PROMETHEUS_OUTPUT_HELP) + buffer_sprintf(opts->wb, "# COMMENT variable \"%s\" is %s.

options to be used for connecting to the server - -Here is an example for 2 servers: - -```sh -mysql_opts[server1]="-h server1.example.com" -mysql_opts[server2]="-h server2.example.com --connect_timeout 2" -``` - -The above will use the `mysql` command found in the system path. -You can also provide a custom mysql command per server, like this: - -```sh -mysql_cmds[server2]="/opt/mysql/bin/mysql" -``` - -The above sets the mysql command only for server2. server1 will use the system default. - -If no configuration is given, the plugin will attempt to

plugins are written in `C` and run as threads inside the netdata daemon. + +- **external** plugins may be written in any computer language and are spawn as independent long-running processes by the netdata daemon. + They communicate with the netdata daemon via `pipes` (`stdout` communication). + +To minimize the number of processes spawn for data collection, netdata also supports **plugin orchestrators**. + +- **plugin orchestrators** are external plugins that do not collect any data by themeselves. + Instead they support data collection **modules** written in the language of the orchestrator. + Usually the orchestrator provides a higher level abstraction, making it ideal for writing new + data collection modules with the minimum of code. + + Currently netdata provides plugin orchestrators + BASH v4+ [charts.d.plugin](charts.d.plugin), + node.js [node.d.plugin](node.d.plugin) and + python v2+ (including v3) [python.d.plugin](python.d.plugin). + +## Netdata Plugins +

of all the plugins with a boolean setting to enable them or disable them. + +The exception is `statsd.plugin` that has its own `[statsd]` section. + +Once a plugin is enabled, consult the page of each plugin for additional configuration options. + +All **external plugins** are managed by [plugins.d](plugins.d/), which provides additional management options. + +### Internal Plugins + +Each of the internal plugins runs as a thread inside the netdata daemon. +Once this thread has started, the plugin may spawn additional threads according to its design. + +#### Internal Plugins API + +The internal data collection API consists of the following calls: + +```c +collect_data() { + // collect data here (one iteration) + + collected_number collected_value = collect_a_value(); + + // give the metrics to netdata + + static RRDSET *st = NULL; // the chart + static RRDDIM *rd = NULL; // a dimension attached to this chart + + if(unlikely(!st)) { + // we haven't created this chart before + // create it now + st = rrdset_create_localhost( + "type" + , "id" + , "name" + , "family" + , "context" + , "Chart Title" + , "units" + , "plugin-name" + , "module-name" + , priority + , update_every + , chart_type + ); + + // attach a metric to it + rd = rrddim_add(st, "id", "name", multiplier, divider, algorithm); + } + else { + // this chart is already created + // let netdata know we start a new iteration on it + rrdset_next(st); + } + + // give the collected value(s) to the chart + rrddim_set_by_pointer(st, rd, collected_value); + + // signal netdata we are done with this iteration + rrdset_done(st); +} +``` + +Of course netdata has a lot of libraries to help you also in collecting the metrics. +The best way to find your way through this, is to examine what other similar plugins do. + + +### External Plugins + +**External plugins** use the API and are managed by [plugins.d](plugins.d/). + diff --git a/collectors/all.h b/collectors/all.h new file mode 100644 index

collecting resource usage information +for every process found running. + +Since netdata needs to present this information in charts and track them through time, +instead of presenting a `top` like list, `apps.plugin` uses a pre-defined list of **process groups** +to which it assigns all running processes. This list is [customizable](apps_groups.conf) and netdata +ships with a good default for most cases (to edit it on your system run `/etc/netdata/edit-config apps_groups.conf`). + +So, `apps.plugin` builds a process tree (much like `ps fax` does in Linux), and groups +processes together (evaluating both child and parent processes) so that the result is always a list with +a predefined set of members (of course, only process groups found running are reported). + +> If you find that `apps.plugin` categorizes standard applications as `other`, we would be +> glad to accept pull requests improving the [defaults](apps_groups.conf) shipped with netdata. + +Unlike traditional process monitoring tools (like `top`), `apps.plugin` is able to account the resource +utilization of exit processes. Their utilization is accounted at their currently running parents. +So, `apps.plugin` is perfectly able to measure the resources used by shell scripts and other processes +that fork/spawn other short lived processes hundreds of times per second. + +## Charts + +`apps.plugin` provides charts for 3 sections: + +1. Per application charts as **Applications** at netdata dashboards +2. Per user charts as **Users** at netdata dashboards +3. Per user group charts as **User Groups** at netdata dashboards + +Each of these sections provides the same number of charts: + +- CPU Utilization + - Total CPU usage + - User / System CPU usage +- Disk I/O + - Physical Reads / Writes + - Logical Reads / Writes + - Open Unique Files (if a file is found open multiple times, it is counted just once) +- Memory + - Real Memory Used (non shared) + - Virtual Memory Allocated + - Minor Page Faults (i.e. memory activity) +- Processes + - Threads Running + - Processes Running + - Pipes Open +- Swap Memory + - Swap Memory Used + - Major Page Faults (i.e. swap activity) +- Network + - Sockets Open + +The above are reported: + +- For **Applications** per [target configured](apps_groups.conf). +- For **Users** per username or UID (when the username is not available). +- For **User Groups** per groupname or GID (when groupname is not available). + +## Performance + +`apps.plugin` is a complex piece of software and has a lot of work to do +We are proud that `apps.plugin` is a lot faster compared to any other similar tool, +while collecting a lot more information for the processes, however the fact is that +this plugin requires more CPU resources than the netdata daemon itself. + +Under Linux, for each process running, `apps.plugin` reads several `/proc` files +per process. Doing this work per-second, especially on hosts with several thousands +of processes, may increase the CPU resources consumed by the plugin. + +In such cases, you many need to lower its data collection frequency. + +To do this, edit `/etc/netdata/netdata.conf` and find this section: + +``` +[plugin:apps] + # update every = 1 + # command options = +``` + +Uncomment the line `update every` and set it to a higher number. If you just set it to ` 2 `, +its CPU resources will be cut in half, and data collection will be once every 2 seconds. + +## Configuration + +The configuration file is `/etc/netdata/apps_groups.conf` (the default is [here](apps_groups.conf)). +To edit it on your system run `/etc/netdata/edit-config apps_groups.conf`. + +The configuration file works accepts multiple lines, each having this format: + +```txt +group: process1 process2 ... +``` + +Each group can be given multiple times, to add more processes to it. + +For the **Applications** section, only groups configured in this file are reported. +All other processes will be reported as `other`. + +For each process given, its whole process tree will be grouped, not just the process matched. +The plugin will include both parents and children. + +The process names are the ones returned by: + + - `ps -e` or `cat /proc/PID/stat` + - in case of substring mode (see below): `/proc/PID/cmdline` + +To add process names with spaces, enclose them in quotes (single or double) +example: ` 'Plex Media Serv' ` or ` "my other process" `. + +You can add an asterisk ` * ` at the beginning and/or the end of a process: + + - `*name` *suffix* mode: will search for processes ending with `name` (at `/proc/PID/stat`) + - `name*` *prefix* mode: will search for processes beginning with `name` (at `/proc/PID/stat`) + - `*name*` *substring* mode: will search for `name` in the whole command line (at `/proc/PID/cmdline`) + +If you enter even just one *name* (substring), `apps.plugin` will process +`/proc/PID/cmdline` for all processes (of course only once per process: when they are first seen). + +To add processes with single quotes, enclose them in double quotes: ` "process with this ' single quote" ` + +To add processes with double quotes, enclose them in single quotes: ` 'process with this " double quote' ` + +If a group or process name starts with a ` - `, the dimension will be hidden from the chart (cpu chart only). + +If a process starts with a ` + `, debugging will be enabled for it (debugging produces a lot of output - do not enable it in production systems). + +You can add any number of groups. Only the ones found running will affect the charts generated. +However, producing charts with hundreds of dimensions may slow down your web browser. + +The order of the entries in this list is important: the first that matches a process is used, so put important +ones at the top. Processes not matched by any row, will inherit it from their parents or children. + +The order also controls the order of the dimensions on the generated charts (although applications started +after apps.plugin is started, will be appended to the existing list of dimensions the netdata daemon maintains). + +## Permissions + +`apps.plugin` requires additional privileges to collect all the information it needs. +The problem is described in issue #157. + +When netdata is installed, `apps.plugin` is given the capabilities `cap_dac_read_search,cap_sys_ptrace+ep`. +If this fails (i.e. `setcap` fails), `apps.plugin` is setuid to `root`. + +#### linux capabilities in containers + +There are a few cases, like `docker` and `virtuozzo` containers, where `setcap` succeeds, but the capabilities +are silently ignored (in `lxc` containers `setcap` fails). + +In these cases ()`setcap` succeeds but capabilities do not work), you will have to setuid +to root `apps.plugin` by running these commands: + +```sh +chown root:netdata /usr/libexec/netdata/plugins.d/apps.plugin +chmod 4750 /usr/libexec/netdata/plugins.d/apps.plugin +``` + +You will have to run these, every time you update netdata. + +## Security + +`apps.plugin` performs a hard-coded function of building the process tree in memory, +iterating forever, collecting metrics for each running process and sending them to netdata. +This is a one-way communication, from `apps.plugin` to netdata. + +So, since `apps.plugin` cannot be instructed by netdata for the actions it performs, +we think it is pretty safe to allow it have these increased privileges. + +Keep in mind that `apps.plugin` will still run without escalated permissions, +but it will not be able to collect all the information. + +## Application Badges + +You can create badges that you can embed anywhere you like, with URLs like this: + +``` +https://your.netdata.ip:19999/api/v1/badge.svg?chart=apps.processes&dimensions=myapp&value_color=green%3E0%7Cred +``` + +The color expression unescaped is this: `value_color=green>0|red`. + +Here is an example for the process group `sql` at `https://registry.my-netdata.io`: + +![image](https://registry.my-netdata.io/api/v1/badge.svg?chart=apps.processes&dimensions=sql&value_color=green%3E0%7Cred) + +Netdata is able give you a lot more badges for your app. +Examples below for process group `sql`: + +- CPU usage: ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.cpu&dimensions=sql&value_color=green=0%7Corange%3C50%7Cred) +- Disk Physical Reads ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.preads&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Disk Physical Writes ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.pwrites&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Disk Logical Reads ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.lreads&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Disk Logical Writes ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.lwrites&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Open Files ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.files&dimensions=sql&value_color=green%3E30%7Cred) +- Real Memory ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.mem&dimensions=sql&value_color=green%3C100%7Corange%3C200%7Cred) +- Virtual Memory ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.vmem&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Swap Memory ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.swap&dimensions=sql&value_color=green=0%7Cred) +- Minor Page Faults ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.minor_faults&dimensions=sql&value_color=green%3C100%7Corange%3C1000%7Cred) +- Processes ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.processes&dimensions=sql&value_color=green%3E0%7Cred) +- Threads ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.threads&dimensions=sql&value_color=green%3E=28%7Cred) +- Major Faults (swap activity) ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.major_faults&dimensions=sql&value_color=green=0%7Cred) +- Open Pipes ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.pipes&dimensions=sql&value_color=green=0%7Cred) +- Open Sockets ![image](http://registry.my-netdata.io/api/v1/badge.svg?chart=apps.sockets&dimensions=sql&value_color=green%3E=3%7Cred) + + +For more information about badges check [Generating Badges](../../web/api/badges) + +## Comparison with console tools + +Ssh to a server running netdata and execute this: + +```sh +while true;

_**Figure 2**: The Applications section at netdata, just a few seconds after the command was run_ + +So, the `ssh` session is using 95% CPU time. + +Why `ssh`? + +`apps.plugin` groups all processes based on its configuration file +[`/etc/netdata/apps_groups.conf`](apps_groups.conf) +(to edit it on your system run `/etc/netdata/edit-config apps_groups.conf`). +The default configuration has nothing for `bash`, but it has for `sshd`, so netdata accumulates +all ssh sessions to a dimension on the charts, called `ssh`. This includes all the processes in +the process tree of `sshd`, **including the exited children**. + +> Distributions based on `systemd`, provide another way to get cpu utilization per user session +> or service running: control groups, or cgroups, commonly used as part of containers +> `apps.plugin` does not use these mechanisms. The process grouping made by `apps.plugin` works +> on any Linux, `systemd` based or not. + +#### a more technical description of how netdata works + +netdata reads `/proc//stat` for all processes, once per second and extracts `utime` and +`stime` (user and system cpu utilization), much like all the console tools do. + +But it [also extracts `cutime` and `cstime`](https://github.com/netdata/netdata/blob/62596cc6b906b1564657510ca9135c08f6d4cdda/src/apps_plugin.c#L636-L642) +that account the user and system time of the exit children of each process. By keeping a map in +memory of the whole process tree, it is capable of assigning the right time to every process, +taking into account all its exited children. + +It is tricky, since a process may be running for 1 hour and once it exits, its parent should not +receive the whole 1 hour of cpu time in just 1 second - you have to subtract the cpu time that has +been reported for it prior to this iteration. + +It is even trickier, because walking through the entire process tree takes some time itself. So, +if you sum the CPU utilization of all processes, you might have more CPU time than the reported +total cpu time of the system. netdata solves this, by adapting the per process cpu utilization to +the total of the system.

When cgroups are bundled with namespaces (i.e. isolation), they form what we usually call **containers**. + +cgroups are hierarchical, meaning that cgroups can contain child cgroups, which can contain more cgroups, etc. All accounting is reported (and resource usage limits are applied) also in a hierarchical way. + +To visualize cgroup metrics netdata provides configuration for cherry picking the cgroups of interest. By default (without any configuration) netdata should pick **systemd services**, all kinds of **containers** (lxc, docker, etc) and **virtual machines** spawn by managers that register them with cgroups (qemu, libvirt, etc). + +## configuring netdata for cgroups + +For each cgroup available in the system, netdata provides this configuration: + +``` +[plugin:cgroups] + enable cgroup XXX = yes | no +``` + +But it also provides a few patterns to provide a sane default (`yes` or `no`). + +Below we see, how this works. + +### how netdata finds the available cgroups + +Linux exposes resource usage reporting and provides dynamic configuration for cgroups, using virtual files (usually) under `/sys/fs/cgroup`. netdata reads `/proc/self/mountinfo` to detect the exact mount point of cgroups. netdata also allows manual configuration of this mount point, using these settings: + +``` +[plugin:cgroups] + check for new cgroups every = 10 + path to /sys/fs/cgroup/cpuacct = /sys/fs/cgroup/cpuacct + path to /sys/fs/cgroup/blkio = /sys/fs/cgroup/blkio + path to /sys/fs/cgroup/memory = /sys/fs/cgroup/memory + path to /sys/fs/cgroup/devices = /sys/fs/cgroup/devices +``` + +netdata rescans these directories for added or removed cgroups every `check for new cgroups every` seconds. + +### hierarchical search for cgroups + +Since cgroups are hierarchical, for each of the directories shown above, netdata walks through the subdirectories recursively searching for cgroups (each subdirectory is another cgroup). + +For each of the directories found, netdata provides a configuration variable: + +``` +[plugin:cgroups] + search for cgroups under PATH = yes | no +``` + +To provide a sane default for this setting, netdata uses the following pattern list (patterns starting with `!` give a negative match and their order is important: the first matching a path will be used): + +``` +[plugin:cgroups] + search for cgroups in subpaths matching = !*/init.scope !*-qemu !/init.scope !/system !/systemd !/user !/user.slice * +``` + +So, we disable checking for **child cgroups** in systemd internal cgroups ([systemd services are monitored by netdata](https://github.com/netdata/netdata/wiki/monitoring-systemd-services)), user cgroups (normally used for desktop and remote user sessions), qemu virtual machines (child cgroups of virtual machines) and `init.scope`. All others are enabled. + + +### enabled cgroups + +To check if the cgroup is enabled, netdata uses this setting: + +``` +[plugin:cgroups] + enable cgroup NAME = yes | no +``` + +To provide a sane default, netdata uses the following pattern list (it checks the pattern against the path of the cgroup): + +``` +[plugin:cgroups] + enable by default cgroups matching = !*/init.scope *.scope !*/vcpu* !*/emulator !*.mount !*.partition !*.service !*.slice !*.swap !*.user !/ !/docker !/libvirt !/lxc !/lxc/*/ns !/lxc/*/ns/* !/machine !/qemu !/system !/systemd !/user * +``` + +The above provides the default `yes` or `no` setting for the cgroup. However, there is an additional step. In many cases the cgroups found in the `/sys/fs/cgroup` hierarchy are just random numbers and in many cases these numbers are ephemeral: they change across reboots or sessions. + +So, we need to somehow map the paths of the cgroups to names, to provide consistent netdata configuration (i.e. there is no point to say `enable cgroup 1234 = yes | no`, if `1234` is a random number that changes over time - we need a name for the cgroup first, so that `enable cgroup NAME = yes | no` will be consistent). + +For this mapping netdata provides 2 configuration options: + +``` +[plugin:cgroups] + run script to rename cgroups matching = *.scope *docker* *lxc* *qemu* !/ !*.mount !*.partition !*.service !*.slice !*.swap !*.user * + script to get cgroup names = /usr/libexec/netdata/plugins.d/cgroup-name.sh +``` + +The whole point for the additional pattern list, is to limit the number of times the script will be called. Without this pattern list, the script might be called thousands of times, depending on the number of cgroups available in the system. + +The above pattern list is matched against the path of the cgroup. For matched cgroups, netdata calls the script [cgroup-name.sh](https://github.com/netdata/netdata/blob/master/collectors/cgroups.plugin/cgroup-name.sh.in) to get its name. This script queries `docker`, or applies heuristics to find give a name for the cgroup. + +## Monitoring systemd services + +netdata monitors **systemd services**.

+# charts.d.plugin + +`charts.d.plugin` is a netdata external plugin. It is an **orchestrator** for data collection modules written in `BASH` v4+. + +1. It runs as an independent process `ps fax` shows it +2. It is started and stopped automatically by netdata +3. It communicates with netdata via a unidirectional pipe (sending data to the netdata daemon) +4. Supports any number of data collection **modules** + +`charts.d.plugin` has been designed so that the actual script that will do data collection will be permanently in +memory, collecting data with as little overheads as possible +(i.e. initialize once, repeatedly collect values with minimal overhead). + +`charts.d.plugin` looks for scripts in `/usr/lib/netdata/charts.d`. +The scripts should have the filename suffix: `.chart.sh`. + +## Configuration + +`charts.d.plugin` itself can be configured using the configuration file `/etc/netdata/charts.d.conf` +(to edit it on your system run `/etc/netdata/edit-config charts.d.conf`). This file is also a BASH script. + +In this file, you can place statements like this: + +``` +enable_all_charts="yes" +X="yes" +Y="no" +``` + +where `X` and `Y` are the names of individual charts.d collector scripts. +When set to `yes`, charts.d will evaluate the collector script (see below). +When set to `no`, charts.d will ignore the collector script. + +The variable `enable_all_charts` sets the default enable/disable state for all charts. + +## A charts.d module + +A `charts.d.plugin` module is a BASH script defining a few functions. + +For a module called `X`, the following criteria must be met: + +1. The module script must be called `X.chart.sh` and placed in `/usr/libexec/netdata/charts.d`. + +2. If the module needs a configuration, it should be called `X.conf` and placed in `/etc/netdata/charts.d`. + The configuration file `X.conf` is also a BASH script itself. + To edit the default files supplied by netdata run `/etc/netdata/edit-config charts.d/X.conf`, + where `X` is the name of the module. + +3. All functions and global variables defined in the script and its configuration, must begin with `X_`. + +4. The following functions must be defined: + + - `X_check()` - returns 0 or 1 depending on whether the module is able to run or not + (following the standard Linux command line return codes: 0 = OK, the collector can operate and 1 = FAILED, + the collector cannot be used). + + - `X_create()` - creates the netdata charts, following the standard netdata plugin guides as described in + **[External Plugins](../plugins.d/)** (commands `CHART` and `DIMENSION`). + The return value does matter: 0 = OK, 1 = FAILED. + + - `X_update()` - collects the values for the defined charts, following the standard netdata plugin guides + as described in **[External Plugins](../plugins.d/)** (commands `BEGIN`, `SET`, `END`). + The return value also matters: 0 = OK, 1 = FAILED. + +5. The following global variables are available to be set: + - `X_update_every` - is the data collection frequency for the module script, in seconds. + +The module script may use more functions or variables. But all of them must begin with `X_`. + +The standard netdata plugin variables are also available (check **[External Plugins](../plugins.d/)**). + +### X_check() + +The purpose of the BASH function `X_check()` is to check if the module can collect data (or check its config). + +For example, if the module is about monitoring a local mysql database, the `X_check()` function may attempt to +connect to a local mysql database to find out if it can read the values it needs. + +`X_check()` is run only once for the lifetime of the module. + +### X_create() + +The purpose of the BASH function `X_create()` is to create the charts and dimensions using the standard netdata +plugin guides (**[External Plugins](../plugins.d/)**). + +`X_create()` will be called just once and only after `X_check()` was successful. +You can however call it yourself when there is need for it (for example to add a new dimension to an existing chart). + +A non-zero return value will disable the collector. + +### X_update() + +`X_update()` will be called repeatedly every `X_update_every` seconds, to collect new values and send them to netdata, +following the netdata plugin guides (**[External Plugins](../plugins.d/)**). + +The function will be called with one parameter: microseconds since the last time it was run. This value should be +appended to the `BEGIN` statement of every chart updated by the collector script. + +A non-zero return value will disable the collector. + +### Useful functions charts.d provides + +Module scripts can use the following charts.d functions: + +#### require_cmd command + +`require_cmd()` will check if a command is available in the running system. + +For example, your `X_check()` function may use it like this: + +```sh +mysql_check() { + require_cmd mysql || return 1 + return 0 +} +``` + +Using the above, if the command `mysql` is not available in the system, the `mysql` module will be disabled. + +#### fixid "string" + +`fixid()` will get a string and return a properly formatted id for a chart or dimension. + +This is an expensive function that should not be used in `X_update()`. +You can keep the generated id in a BASH associative array to have the values availables in `X_update()`, like this: + +```sh +declare -A X_ids=() +X_create() { + local name="a very bad name for id" + + X_ids[$name]="$(fixid "$name")" +} + +X_update() { + local microseconds="$1" + + ... + local name="a very bad name for id" + ... + + echo "BEGIN ${X_ids[$name]} $microseconds" + ... +} +``` + +### Debugging your collectors + +You can run `charts.d.plugin` by hand with something like this: + +```sh +# become user netdata +sudo su -s /bin/sh netdata + +# run the plugin in debug mode +/usr/libexec/netdata/plugins.d/charts.d.plugin debug 1 X Y Z +``` + +Charts.d will run in `debug` mode, with an update frequency of `1`, evaluating only the collector scripts +`X`, `Y` and `Z`. You can define zero or more module scripts. If none is defined, charts.d will evaluate all +module scripts available. + +Keep in mind that if your configs are not in `/etc/netdata`, you should do the following before running +`charts.d.plugin`: + +```sh +export NETDATA_USER_CONFIG_DIR="/path/to/etc/netdata" +``` + +Also, remember that netdata runs `chart.d.plugin` as user `netdata` (or any other user netdata is configured to run as). + + +## Running multiple instances of charts.d.plugin + +`charts.d.plugin` will call the `X_update()` function one after another. This means that a delay in collector `X` +will also delay the collection of `Y` and `Z`. + +You can have multiple `charts.d.plugin` running to overcome this problem. + +This is what you need to do: + +1. Decide a new name for the new charts.d instance: example `charts2.d`. + +2. Create/edit the files `/etc/netdata/charts.d.conf` and `/etc/netdata/charts2.d.conf` and enable / disable the + module you want each to run. Remember to set `enable_all_charts="no"` to both of them, and enable the individual + modules for each. + +3. link `/usr/libexec/netdata/plugins.d/charts.d.plugin` to `/usr/libexec/netdata/plugins.d/charts2.d.plugin`. + Netdata will spawn a new charts.d process. + +Execute the above in this order, since netdata will (by default) attempt to start new plugins soon after they are +created in `/usr/libexec/netdata/plugins.d/`. + diff --git a/collectors/charts.d.plugin/ap/Makefile.inc b/collectors/charts.d.plugin/ap/Makefile.inc new file mode 100644 index 000000000..a2dd375ac --- /dev/null +++ b/collectors/charts.d.plugin/ap/Makefile.inc @@ -0,0 +1,13 @@ +# SPDX-License-Identifier: GPL-3.0-or-later + +# THIS IS NOT A COMPLETE Makefile +# IT IS INCLUDED BY ITS PARENT'S Makefile.am +# IT IS REQUIRED TO REFERENCE ALL FILES RELATIVE TO THE PARENT + +# install these files +dist_charts_DATA += ap/ap.chart.sh +dist_chartsconfig_DATA += ap/ap.conf + +# do not install these files, but include them in the distribution +dist_noinst_DATA += ap/README.md ap/Makefile.inc + diff --git a/collectors/charts.d.plugin/ap/README.md b/collectors/charts.d.plugin/ap/README.md new file mode 100644 index 000000000..eb4e80707 --- /dev/null +++ b/collectors/charts.d.plugin/ap/README.md @@ -0,0 +1,84 @@ +# Access Point Plugin (ap) + +The `ap` collector visualizes data related to access points. + +## Example netdata charts + +![image](https://cloud.githubusercontent.com/assets/2662304/12377654/9f566e88-bd2d-11e5-855a-e0ba96b8fd98.png) + +## How it works + +It does the following: + +1.

node.d.plugin + +`node.d.plugin` is a netdata external plugin.

It is very fast and quite common (actually the whole web is based on it). +Since data collection is not a CPU intensive task, node.js is an ideal solution for it. + +`node.d.plugin` is a netdata plugin that provides an abstraction layer to allow easy and quick development of data +collectors in node.js. It also manages all its data collectors (placed in `/usr/libexec/netdata/node.d`) using a single +instance of node, thus lowering the memory footprint of data collection. + +Of course, there can be independent plugins written in node.js (placed in `/usr/libexec/netdata/plugins`). +These will have to be developed using the guidelines of **[External Plugins](../plugins.d/)**. + +To run `node.js` plugins you need to have `node` installed in your system. + +In some older systems, the package named `node` is not node.js. It is a terminal emulation program called `ax25-node`. +In this case the node.js package may be referred as `nodejs`. Once you install `nodejs`, we suggest to link +`/usr/bin/nodejs` to `/usr/bin/node`, so that typing `node` in your terminal, opens node.js. +For more information check the **[[Installation]]** guide. + +## configuring `node.d.plugin` + +`node.d.plugin` can work even without any configuration. Its default configuration file is +[/etc/netdata/node.d.conf](node.d.conf) (to edit it on your system run `/etc/netdata/edit-config node.d.conf`). + +## configuring `node.d.plugin` modules + +`node.d.plugin` modules accept configuration in `JSON` format. + +Unfortunately, `JSON` files do not accept comments. So, the best way to describe them is to have markdown text files +with instructions. + +`JSON` has a very strict formatting. If you get errors from netdata at `/var/log/netdata/error.log` that a certain +configuration file cannot be loaded, we suggest to verify it at [http://jsonlint.com/](http://jsonlint.com/). + +The files in this directory, provide usable examples for configuring each `node.d.plugin` module. + + +## debugging modules written for node.d.plugin + +To test `node.d.plugin` modules, which are placed in `/usr/libexec/netdata/node.d`, you can run `node.d.plugin` by hand, +like this: + +```sh +# become user netdata +sudo su -s /bin/sh netdata + +# run the plugin in debug mode +/usr/libexec/netdata/plugins.d/node.d.plugin debug 1 X Y Z +``` + +`node.d.plugin` will run in `debug` mode (lots of debug info), with an update frequency of `1` second, evaluating only +the collector scripts `X` (i.e. `/usr/libexec/netdata/node.d/X.node.js`), `Y` and `Z`. +You can define zero or more modules. If none is defined, `node.d.plugin` will evaluate all modules available. + +Keep in mind that if your configs are not in `/etc/netdata`, you should do the following before running `node.d.plugin`: + +```sh +export NETDATA_USER_CONFIG_DIR="/path/to/etc/netdata" +``` + +--- + +## developing `node.d.plugin` modules + +Your data collection module should be split in 3 parts: + + - a function to fetch the data from its source. `node.d.plugin` already can fetch data from web sources, + so you don't need to do anything about it for http. + + - a function to process the fetched/manipulate the data fetched. This function will make a number of calls + to create charts and dimensions and pass the collected values to netdata. + This is the only function you need to write for collecting http JSON data. + + - a `configure` and an `update` function, which take care of your module configuration and data refresh + respectively. You can use the supplied ones. + +Your module will automatically be able to process any number of servers, with different settings (even different +data collection frequencies). You will write just the work needed for one and `node.d.plugin` will do the rest. +For each server you are going to fetch data from, you will have to create a `service` (more later). + +### writing the data collection module + +To provide a module called `mymodule`, you have create the file `/usr/libexec/netdata/node.d/mymodule.node.js`, with this structure: + +```js + +// the processor is needed only +// if you need a custom processor +// other than http +netdata.processors.myprocessor = { + name: 'myprocessor', + + process: function(service, callback) { + + /* do data collection here */ + + callback(data); + } +}; + +// this is the mymodule definition +var mymodule = { + processResponse: function(service, data) { + + /* send information to the netdata server here */ + + }, + + configure: function(config) { + var eligible_services = 0; + + if(typeof(config.servers) === 'undefined' || config.servers.length === 0) { + + /* + * create a service using internal defaults; + * this is used for auto-detecting the settings + * if possible + */ + + netdata.service({ + name: 'a name for this service', + update_every: this.update_every, + module: this, + processor: netdata.processors.myprocessor, + // any other information your processor needs + }).execute(this.processResponse); + + eligible_services++; + } + else { + + /* + * create a service for each server in the + * configuration file + */ + + var len = config.servers.length; + while(len--) { + var server = config.servers[len]; + + netdata.service({ + name: server.name, + update_every: server.update_every, + module: this, + processor: netdata.processors.myprocessor, + // any other information your processor needs + }).execute(this.processResponse); + + eligible_services++; + } + } + + return eligible_services; + }, + + update: function(service, callback) { + + /* + * this function is called when each service + * created by the configure function, needs to + * collect updated values. + * + * You normally will not need to change it. + */ + + service.execute(function(service, data) { + mymodule.processResponse(service, data); + callback(); + }); + }, +}; + +module.exports = mymodule; +``` + +#### configure(config) + +`configure(config)` is called just once, when `node.d.plugin` starts. +The config file will contain the contents of `/etc/netdata/node.d/mymodule.conf`. +This file should have the following format: + +```js +{ + "enable_autodetect": false, + "update_every": 5, + "servers": [ { /* server 1 */ }, { /* server 2 */ } ] +} +``` + +If the config file `/etc/netdata/node.d/mymodule.conf` does not give a `enable_autodetect` or `update_every`, these +will be added by `node.d.plugin`.

Clients +- Global Queries by IP Protocol (TCP, UDP) +- Global Queries Analysis +- Global Received Updates +- Global Query Failures +- Global Query Failures Analysis +- Other Global Server Statistics +- Global Incoming Requests by OpCode +- Global Incoming Requests by Query Type +- Global Socket Statistics (will only work if the url is `http://127.0.0.1:8888/json/v1`, i.e. without `/server`, but keep in mind this produces a very long output and probably will account for 0.5% CPU overhead alone, per bind server added) +- Per View Statistics (the following set will be added for each bind view): + - View, Resolver Active Queries + - View, Resolver Statistics + - View, Resolver Round Trip Timings + - View, Requests by Query Type + +## Configuration + +The collector (optionally) reads a configuration file named `/etc/netdata/node.d/named.conf`, with the following contents: + +```js +{ + "enable_autodetect": true, + "update_every": 5, + "servers": [ + { + "name": "bind1", + "url": "http://127.0.0.1:8888/json/v1/server", + "update_every": 1 + }, + { + "name": "bind2", + "url": "http://10.1.2.3:8888/json/v1/server", + "update_every": 2 + } + ] +} +``` + +You can add any number of bind servers. + +If the configuration file is missing, or the key `enable_autodetect` is `true`, the collector will also attempt to fetch `http://localhost:8888/json/v1/server` which, if successful will be added too. + +### XML instead of JSON, from bind + +The collector can also accept bind URLs that return XML output. This might required if you cannot have bind 9.10+ with JSON but you have an version of bind that supports XML statistics v3. Check [this](https://www.isc.org/blogs/bind-9-10-statistics-troubleshooting-and-zone-configuration/) for versions supported. + +In such cases, use a URL like this: + +```sh +curl "http://localhost:8888/xml/v3/server" +``` + +Only `xml` and `v3` has been tested. + +Keep in mind though, that XML parsing is done using javascript code, which requires a triple conversion: + +1. from XML to JSON using a javascript XML parser (**CPU intensive**), +2. which is then transformed to emulate the output of the JSON output of bind (**CPU intensive** - and yes the converted JSON from XML is different to the native JSON - even bind produces different names for various attributes), +3. which is then processed to generate the data for the charts (this will happen even if bind is producing JSON). + +In general, expect XML parsing to be 2 to 3 times more CPU intensive than JSON. + +**So, if you can use the JSON output of bind, prefer it over XML**. Keep also in mind that even bind will use more CPU when generating XML instead of JSON. + +The XML interface of bind is not autodetected. +You will have to provide the config file `/etc/netdata/node.d/named.conf`, like this: + +```js +{ + "enable_autodetect": false, + "update_every": 1, + "servers": [ + { + "name": "local", + "url": "http://localhost:8888/xml/v3/server", + "update_every": 1 + } + ] +} +``` + +Of course, you can monitor more than one bind servers. Each one can be configured with either JSON or XML output. + +## Auto-detection + +Auto-detection is controlled by `enable_autodetect` in the config file. The default is enabled, so that if the collector can connect to `http://localhost:8888/json/v1/server` to receive bind statistics, it will automatically enable it. + +## Bind (named) configuration + +To use this plugin, you have to have bind v9.10+ properly compiled to provide statistics in `JSON` format. + +For more information on how to get your bind installation ready, please refer to the [bind statistics channel developer comments](http://jpmens.net/2013/03/18/json-in-bind-9-s-statistics-server/) and to [bind documentation](https://ftp.isc.org/isc/bind/9.10.3/doc/arm/Bv9ARM.ch06.html#statistics) or [bind Knowledge Base article AA-01123](https://kb.isc.org/article/AA-01123/0). + +Normally, you will need something like this in your `named.conf`: + +``` +statistics-channels { + inet 127.0.0.1 port 8888 allow { 127.0.0.1;

They are modular since they accept custom made modules to be included. Writing modules for these plugins is easier than accessing the native netdata API directly. You will find modules already available for each orchestrator under the directory of the particular modular plugin (e.g. under python.d.plugin for the python orchestrator). +Each of these modular plugins has each own methods for defining modules. Please check the examples and their documentation. + +## Motivation + +This plugin allows netdata to use **external plugins** for data collection: + +1. external data collection plugins may be written in any computer language. + +2. external data collection plugins may use O/S capabilities or `setuid` to + run with escalated privileges (compared to the netdata daemon). + The communication between the external plugin and netdata is unidirectional + (from the plugin to netdata), so that netdata cannot manipulate an external + plugin running with escalated privileges. + +## Operation + +Each of the external plugins is expected to run forever. +Netdata will start it when it starts and stop it when it exits. + +If the external plugin exits or crashes, netdata will log an error. +If the external plugin exits or crashes without pushing metrics to netdata, netdata will not start it again. +- Plugins that exit with any value other than zero, will be disabled. Plugins that exit with zero, will be restarted after some time. +- Plugins may also be disabled by netdata if they output things that netdata does not understand. + +The `stdout` of external plugins is connected to netdata to receive metrics, +with the API defined below. + +The `stderr` of external plugins is connected to netdata `error.log`. + +Plugins can create any number of charts with any number of dimensions each. Each chart can have its own characteristics independently of the others generated by the same plugin. For example, one chart may have an update frequency of 1 second, another may have 5 seconds and a third may have 10 seconds. + +## Configuration + +Netdata will supply the environment variables `NETDATA_USER_CONFIG_DIR` (for user supplied) and `NETDATA_STOCK_CONFIG_DIR` (for netdata supplied) configuration files to identify the directory where configuration files are stored. It is up to the plugin to read the configuration it needs. + +The `netdata.conf` section [plugins] section contains a list of all the plugins found at the system where netdata runs, with a boolean setting to enable them or not. + +Example: + +``` +[plugins] + # enable running new plugins = yes + # check for new plugins every = 60 + + # charts.d = yes + # fping = yes + # node.d = yes + # python.d = yes +``` + +The setting `enable running new plugins` changes the default behavior for all external plugins. +So if set to `no`, only the plugins that are explicitly set to `yes` will be run. + +The setting `check for new plugins every` controls the time the directory `/usr/libexec/netdata/plugins.d` +will be rescanned for new plugins. So, new plugins can give added anytime. + +For each of the external plugins enabled, another `netdata.conf` section +is created, in the form of `[plugin:NAME]`, where `NAME` is the name of the external plugin. +This section allows controlling the update frequency of the plugin and provide +additional command line arguments to it. + +For example, for `apps.plugin` the following section is available: + +``` +[plugin:apps] + # update every = 1 + # command options = +``` + +- `update every` controls the granularity of the external plugin. +- `command options` allows giving additional command line options to the plugin. + + +Netdata will provide to the extrenal plugins the environment variable `NETDATA_UPDATE_EVERY`, in seconds (the default is 1). This is the **minimum update frequency** for all charts. A plugin that is updating values more frequently than this, is just wasting resources. + +Netdata will call the plugin with just one command line parameter: the number of seconds the user requested this plugin to update its data (by default is also 1). + +Other than the above, the plugin configuration is up to the plugin. + +Keep in mind, that the user may use netdata configuration to overwrite chart and dimension parameters. This is transparent to the plugin. + +### Autoconfiguration + +Plugins should attempt to autoconfigure themselves when possible. + +For example, if your plugin wants to monitor `squid`, you can search for it on port `3128` or `8080`. If any succeeds, you can proceed. If it fails you can output an error (on stderr) saying that you cannot find `squid` running and giving instructions about the plugin configuration. Then you can stop (exit with non-zero value), so that netdata will not attempt to start the plugin again. + +## External Plugins API + +Any program that can print a few values to its standard output can become a netdata external plugin. + +There are 7 lines netdata parses. lines starting with: + +- `CHART` - create or update a chart +- `DIMENSION` - add or update a dimension to the chart just created +- `BEGIN` - initialize data collection for a chart +- `SET` - set the value of a dimension for the initialized chart +- `END` - complete data collection for the initialized chart +- `FLUSH` - ignore the last collected values +- `DISABLE` - disable this plugin + +a single program can produce any number of charts with any number of dimensions each. + +Charts can be added any time (not just the beginning). + +### command line parameters + +The plugin **MUST** accept just **one** parameter: **the number of seconds it is +expected to update the values for its charts**. The value passed by netdata +to the plugin is controlled via its configuration file (so there is no need +for the plugin to handle this configuration option). + +The external plugin can overwrite the update frequency. For example, the server may +request per second updates, but the plugin may ignore it and update its charts +every 5 seconds. + +### environment variables + +There are a few environment variables that are set by `netdata` and are +available for the plugin to use. + +variable|description +:------:|:---------- +`NETDATA_USER_CONFIG_DIR`|The directory where all netdata related user configuration should be stored. If the plugin requires custom user configuration, this is the place the user has saved it (normally under `/etc/netdata`). +`NETDATA_STOCK_CONFIG_DIR`|The directory where all netdata related stock configuration should be stored. If the plugin is shipped with configuration files, this is the place they can be found (normally under `/usr/lib/netdata/conf.d`). +`NETDATA_PLUGINS_DIR`|The directory where all netdata plugins are stored. +`NETDATA_WEB_DIR`|The directory where the web files of netdata are saved. +`NETDATA_CACHE_DIR`|The directory where the cache files of netdata are stored. Use this directory if the plugin requires a place to store data. A new directory should be created for the plugin for this purpose, inside this directory. +`NETDATA_LOG_DIR`|The directory where the log files are stored. By default the `stderr` output of the plugin will be saved in the `error.log` file of netdata. +`NETDATA_HOST_PREFIX`|This is used in environments where system directories like `/sys` and `/proc` have to be accessed at a different path. +`NETDATA_DEBUG_FLAGS`|This is a number (probably in hex starting with `0x`), that enables certain netdata debugging features. Check **[[Tracing Options]]** for more information. +`NETDATA_UPDATE_EVERY`|The minimum number of seconds between chart refreshes. This is like the **internal clock** of netdata (it is user configurable, defaulting to `1`). There is no meaning for a plugin to update its values more frequently than this number of seconds. + + +### The output of the plugin + +The plugin should output instructions for netdata to its output (`stdout`). Since this uses pipes, please make sure you flush stdout after every iteration. + +#### DISABLE + +`DISABLE` will disable this plugin. This will prevent netdata from restarting the plugin. You can also exit with the value `1` to have the same effect. + +#### CHART + +`CHART` defines a new chart. + +the template is: + +> CHART type.id name title units [family [context [charttype [priority [update_every [options [plugin [module]]]]]]]] + + where: + - `type.id` + + uniquely identifies the chart, + this is what will be needed to add values to the chart + + the `type` part controls the menu the charts will appear in + + - `name` + + is the name that will be presented to the user instead of `id` in `type.id`. This means that only the `id` part of `type.id` is changed. When a name has been given, the chart is index (and can be referred) as both `type.id` and `type.name`.

This is to used for setting constants (like the max connections a server may accept). + +Variables support 2 scopes: + +- `GLOBAL` or `HOST` to define the variable at the host level. +- `LOCAL` or `CHART` to define the variable at the chart level. Use chart-local variables when the same variable may exist for different charts (i.e. netdata monitors 2 mysql servers, and you need to set the `max_connections` each server accepts). Using chart-local variables is the ideal to build alarm templates. + +The position of the `VARIABLE` line, sets its default scope (in case you do not specify a scope). So, defining a `VARIABLE` before any `CHART`, or between `END` and `BEGIN` (outside any chart), sets `GLOBAL` scope, while defining a `VARIABLE` just after a `CHART` or a `DIMENSION`, or within the `BEGIN` - `END` block of a chart, sets `LOCAL` scope. + +These variables can be set and updated at any point. + +Variable names should use alphanumeric characters, the `.` and the `_`. + +The `value` is floating point (netdata used `long double`). + +Variables are transferred to upstream netdata servers (streaming and database replication). + +## Data collection + +data collection is defined as a series of `BEGIN` -> `SET` -> `END` lines + +> BEGIN type.id [microseconds] + + - `type.id` + + is the unique identification of the chart (as given in `CHART`) + + - `microseconds` + + is the number of microseconds since the last update of the chart. It is optional. + + Under heavy system load, the system may have some latency transferring + data from the plugins to netdata via the pipe. This number improves + accuracy significantly, since the plugin is able to calculate the + duration between its iterations better than netdata. + + The first time the plugin is started, no microseconds should be given + to netdata. + +> SET id = value + + - `id` + + is the unique identification of the dimension (of the chart just began) + + - `value` + + is the collected value, only integer values are collected. If you want to push fractional values, multiply this value by 100 or 1000 and set the `DIMENSION` divider to 1000. + +> END + + END does not take any parameters, it commits the collected values for all dimensions to the chart. If a dimensions was not `SET`, its value will be empty for this commit. + +More `SET` lines may appear to update all the dimensions of the chart. +All of them in one `BEGIN` -> `END` block. + +All `SET` lines within a single `BEGIN` -> `END` block have to refer to the +same chart. + +If more charts need to be updated, each chart should have its own +`BEGIN` -> `SET` -> `END` block. + +If, for any reason, a plugin has issued a `BEGIN` but wants to cancel it, +it can issue a `FLUSH`. The `FLUSH` command will instruct netdata to ignore +all the values collected since the last `BEGIN` command. + +If a plugin does not behave properly (outputs invalid lines, or does not +follow these guidelines), will be disabled by netdata. + +### collected values + +netdata will collect any **signed** value in the 64bit range: +`-9.223.372.036.854.775.808` to `+9.223.372.036.854.775.807` + +If a value is not collected, leave it empty, like this: + +`SET id = ` + +or do not output the line at all. + +## Modular Plugins + +1. **python**, use `python.d.plugin`, there are many examples in the [python.d directory](../python.d.plugin) + + python is ideal for netdata plugins. It is a simple, yet powerful way to collect data, it has a very small memory footprint, although it is not the most CPU efficient way to do it. + +2. **node.js**, use `node.d.plugin`, there are a few examples in the [node.d directory](../node.d.plugin) + + node.js is the fastest scripting language for collecting data. If your plugin needs to do a lot of work, compute values, etc, node.js is probably the best choice before moving to compiled code. Keep in mind though that node.js is not memory efficient; it will probably need more RAM compared to python. + +3. **BASH**, use `charts.d.plugin`, there are many examples in the [charts.d directory](../charts.d.plugin) + + BASH is the simplest scripting language for collecting values. It is the less efficient though in terms of CPU resources. You can use it to collect data quickly, but extensive use of it might use a lot of system resources. + +4. **C** + + Of course, C is the most efficient way of collecting data. This is why netdata itself is written in C. + +--- + +## Writing Plugins Properly + +There are a few rules for writing plugins properly: + +1. Respect system resources + + Pay special attention to efficiency: + + - Initialize everything once, at the beginning. Initialization is not an expensive operation. Your plugin will most probably be started once and run forever. So, do whatever heavy operation is needed at the beginning, just once. + - Do the absolutely minimum while iterating to collect values repeatedly. + - If you need to connect to another server to collect values, avoid re-connects if possible. Connect just once, with keep-alive (for HTTP) enabled and collect values using the same connection. + - Avoid any CPU or memory heavy operation while collecting data. If you control memory allocation, avoid any memory allocation white iterating to collect values. + - Avoid running external commands when possible. If you are writing shell scripts avoid especially pipes (each pipe is another fork, a very expensive operation). + +2. The best way to iterate at a constant pace is this pseudo code: + +```js + var update_every = argv[1] * 1000; /* seconds * 1000 = milliseconds */ + + readConfiguration(); + + if(!verifyWeCanCollectValues()) { + print "DISABLE"; + exit(1); + } + + createCharts(); /* print CHART and DIMENSION statements */ + + var loops = 0; + var last_run = 0; + var next_run = 0; + var dt_since_last_run = 0; + var now = 0; + + FOREVER { + /* find the current time in milliseconds */ + now = currentTimeStampInMilliseconds(); + + /* + * find the time of the next loop + * this makes sure we are always aligned + * with the netdata daemon + */ + next_run = now - (now % update_every) + update_every; + + /* + * wait until it is time + * it is important to do it in a loop + * since many wait functions can be interrupted + */ + while( now < next_run ) { + sleepMilliseconds(next_run - now); + now = currentTimeStampInMilliseconds(); + } + + /* calculate the time passed since the last run */ + if ( loops > 0 ) + dt_since_last_run = (now - last_run) * 1000; /* in microseconds */ + + /* prepare for the next loop */ + last_run = now; + loops++; + + /* do your magic here to collect values */ + collectValues(); + + /* send the collected data to netdata */ + printValues(dt_since_last_run); /* print BEGIN, SET, END statements */ + } +``` + + Using the above procedure, your plugin will be synchronized to start data collection on steps of `update_every`. There will be no need to keep track of latencies in data collection. + + Netdata interpolates values to second boundaries, so even if your plugin is not perfectly aligned it does not matter. Netdata will find out. When your plugin works in increments of `update_every`, there will be no gaps in the charts due to the possible cumulative micro-delays in data collection. Gaps will only appear if the data collection is really delayed. + +3. If you are not sure of memory leaks, exit every one hour. Netdata will re-start your process. + +4. If possible, try to autodetect if your plugin should be enabled, without any configuration. diff --git a/collectors/plugins.d/plugins_d.c b/collectors/plugins.d/plugins_d.c new file mode 100644 index 000000000..465ecd796 --- /dev/null +++ b/collectors/plugins.d/plugins_d.c @@ -0,0 +1,696 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "plugins_d.h" + +char *plugin_directories[PLUGINSD_MAX_DIRECTORIES] = { NULL }; +char *netdata_configured_plugins_dir_base; + +struct plugind *pluginsd_root = NULL; + +static inline int pluginsd_space(char c) { + switch(c) { + case ' ': + case '\t': + case '\r': + case '\n': + case '=': + return 1; + + default: + return 0; + } +} + +inline int config_isspace(char c) { + switch(c) { + case ' ': + case '\t': + case '\r': + case '\n': + case ',': + return 1; + + default: + return 0; + } +} + +// split a text into words, respecting quotes +inline int quoted_strings_splitter(char *str, char **words, int max_words, int (*custom_isspace)(char)) { + char *s = str, quote = 0; + int i = 0, j; + + // skip all white space + while(unlikely(custom_isspace(*s))) s++; + + // check for quote + if(unlikely(*s == '\'' || *s == '"')) { + quote = *s; // remember the quote + s++; // skip the quote + } + + // store the first word + words[i++] = s; + + // while we have something + while(likely(*s)) { + // if it is escape + if(unlikely(*s == '\\' && s[1])) { + s += 2; + continue; + } + + // if it is quote + else if(unlikely(*s == quote)) { + quote = 0; + *s = ' '; + continue; + } + + // if it is a space + else if(unlikely(quote == 0 && custom_isspace(*s))) { + + // terminate the word + *s++ = '\0'; + + // skip all white space + while(likely(custom_isspace(*s))) s++; + + // check for quote + if(unlikely(*s == '\'' || *s == '"')) { + quote = *s; // remember the quote + s++; // skip the quote + } + + // if we reached the end, stop + if(unlikely(!*s)) break; + + // store the next word + if(likely(i < max_words)) words[i++] = s; + else break; + } + + // anything else + else s++; + } + + // terminate the words + j = i; + while(likely(j < max_words)) words[j++] = NULL; + + return i; +} + +inline int pluginsd_split_words(char *str, char **words, int max_words) { + return quoted_strings_splitter(str, words, max_words, pluginsd_space); +} + +inline size_t pluginsd_process(RRDHOST *host, struct plugind *cd, FILE *fp, int trust_durations) { + int enabled = cd->enabled; + + if(!fp || !enabled) { + cd->enabled = 0; + return 0; + } + + size_t count = 0; + + char line[PLUGINSD_LINE_MAX + 1]; + + char *words[PLUGINSD_MAX_WORDS] = { NULL }; + uint32_t BEGIN_HASH = simple_hash(PLUGINSD_KEYWORD_BEGIN); + uint32_t END_HASH = simple_hash(PLUGINSD_KEYWORD_END); + uint32_t FLUSH_HASH = simple_hash(PLUGINSD_KEYWORD_FLUSH); + uint32_t CHART_HASH = simple_hash(PLUGINSD_KEYWORD_CHART); + uint32_t DIMENSION_HASH = simple_hash(PLUGINSD_KEYWORD_DIMENSION); + uint32_t DISABLE_HASH = simple_hash(PLUGINSD_KEYWORD_DISABLE); + uint32_t VARIABLE_HASH = simple_hash(PLUGINSD_KEYWORD_VARIABLE); + + RRDSET *st = NULL; + uint32_t hash; + + errno = 0; + clearerr(fp); + + if(unlikely(fileno(fp) == -1)) { + error("file descriptor given is not a valid stream"); + goto cleanup; + } + + while(!ferror(fp)) { + if(unlikely(netdata_exit)) break; + + char *r = fgets(line, PLUGINSD_LINE_MAX, fp); + if(unlikely(!r)) { + error("read failed"); + break; + } + + if(unlikely(netdata_exit)) break; + + line[PLUGINSD_LINE_MAX] = '\0'; + + int w = pluginsd_split_words(line, words, PLUGINSD_MAX_WORDS); + char *s = words[0]; + if(unlikely(!s || !*s || !w)) { + continue; + } + + // debug(D_PLUGINSD, "PLUGINSD: words 0='%s' 1='%s' 2='%s' 3='%s' 4='%s' 5='%s' 6='%s' 7='%s' 8='%s' 9='%s'", words[0], words[1], words[2], words[3], words[4], words[5], words[6], words[7], words[8], words[9]); + + if(likely(!simple_hash_strcmp(s, "SET", &hash))) { + char *dimension = words[1]; + char *value = words[2]; + + if(unlikely(!dimension || !*dimension)) { + error("requested a SET on chart '%s' of host '%s', without a dimension.

The main reason is the plethora of disk technologies available. There are many different hardware disk technologies, but there are even more **virtual disk** technologies that can provide additional storage features. + +Hopefully, the Linux kernel provides many metrics that can provide deep insights of what our disks our doing. The kernel measures all these metrics on all layers of storage: **virtual disks**, **physical disks** and **partitions of disks**. + +Let's see the list of metrics provided by netdata for each of the above: + +### I/O bandwidth/s (kb/s) + +The amount of data transferred from and to the disk. + +### I/O operations/s + +The number of I/O operations completed. + +### Queued I/O operations + +The number of currently queued I/O operations. For traditional disks that execute commands one after another, one of them is being run by the disk and the rest are just waiting in a queue. + +### Backlog size (time in ms) + +The expected duration of the currently queued I/O operations. + +### Utilization (time percentage) + +The percentage of time the disk was busy with something. This is a very interesting metric, since for most disks, that execute commands sequentially, **this is the key indication of congestion**. A sequential disk that is 100% of the available time busy, has no time to do anything more, so even if the bandwidth or the number of operations executed by the disk is low, its capacity has been reached. + +Of course, for newer disk technologies (like fusion cards) that are capable to execute multiple commands in parallel, this metric is just meaningless. + +### Average I/O operation time (ms) + +The average time for I/O requests issued to the device to be served. This includes the time spent by the requests in queue and the time spent servicing them. + +### Average I/O operation size (kb) + +The average amount of data of the completed I/O operations. + +### Average Service Time (ms) + +The average service time for completed I/O operations. This metric is calculated using the total busy time of the disk and the number of completed operations. If the disk is able to execute multiple parallel operations the reporting average service time will be misleading. + +### Merged I/O operations/s + +The Linux kernel is capable of merging I/O operations. So, if two requests to read data from the disk are adjacent, the Linux kernel may merge them to one before giving them to disk. This metric measures the number of operations that have been merged by the Linux kernel. + +### Total I/O time + +The sum of the duration of all completed I/O operations. This number can exceed the interval if the disk is able to execute multiple I/O operations in parallel. + +### Space usage + +For mounted disks, netdata will provide a chart for their space, with 3 dimensions: + +1. free +2. used +3. reserved for root + +### inode usage + +For mounted disks, netdata will provide a chart for their inodes (number of file and directories), with 3 dimensions: + +1. free +2. used +3. reserved for root + +--- + +## disk names + +netdata will automatically set the name of disks on the dashboard, from the mount point they are mounted, of course only when they are mounted. Changes in mount points are not currently detected (you will have to restart netdata to change the name of the disk). + +--- + +## performance metrics + +By default netdata will enable monitoring metrics only when they are not zero. If they are constantly zero they are ignored. Metrics that will start having values, after netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though). + +netdata categorizes all block devices in 3 categories: + +1. physical disks (i.e. block devices that does not have slaves and are not partitions) +2. virtual disks (i.e. block devices that have slaves - like RAID devices) +3. disk partitions (i.e. block devices that are part of a physical disk) + +Performance metrics are enabled by default for all disk devices, except partitions and not-mounted virtual disks. Of course, you can enable/disable monitoring any block device by editing the netdata configuration file. + +### netdata configuration + +You can get the running netdata configuration using this: + +```sh +cd /etc/netdata +curl "http://localhost:19999/netdata.conf" >netdata.conf.new +mv netdata.conf.new netdata.conf +``` + +Then edit `netdata.conf` and find the following section. This is the basic plugin configuration. + +``` +[plugin:proc:/proc/diskstats] + # enable new disks detected at runtime = yes + # performance metrics for physical disks = auto + # performance metrics for virtual disks = no + # performance metrics for partitions = no + # performance metrics for mounted filesystems = no + # performance metrics for mounted virtual disks = auto + # space metrics for mounted filesystems = auto + # bandwidth for all disks = auto + # operations for all disks = auto + # merged operations for all disks = auto + # i/o time for all disks = auto + # queued operations for all disks = auto + # utilization percentage for all disks = auto + # backlog for all disks = auto + # space usage for all disks = auto + # inodes usage for all disks = auto + # filename to monitor = /proc/diskstats + # path to get block device infos = /sys/dev/block/%lu:%lu/%s + # path to get h/w sector size = /sys/block/%s/queue/hw_sector_size + # path to get h/w sector size for partitions = /sys/dev/block/%lu:%lu/subsystem/%s/../queue +/hw_sector_size + +``` + +For each virtual disk, physical disk and partition you will have a section like this: + +``` +[plugin:proc:/proc/diskstats:sda] + # enable = yes + # enable performance metrics = auto + # bandwidth = auto + # operations = auto + # merged operations = auto + # i/o time = auto + # queued operations = auto + # utilization percentage = auto + # backlog = auto +``` + +For all configuration options: +- `auto` = enable monitoring if the collected values are not zero +- `yes` = enable monitoring +- `no` = disable monitoring + +Of course, to set options, you will have to uncomment them. The comments show the internal defaults. + +After saving `/etc/netdata/netdata.conf`, restart your netdata to apply them. + +#### Disabling performance metrics for individual device and to multiple devices by device type +You can pretty easy disable performance metrics for individual device, for ex.: +``` +[plugin:proc:/proc/diskstats:sda] + enable performance metrics = no +``` +But sometimes you need disable performance metrics for all devices with the same type, to do it you need to figure out device type from `/proc/diskstats` for ex.: +``` + 7 0 loop0 1651 0 3452 168 0 0 0 0 0 8 168 + 7 1 loop1 4955 0 11924 880 0 0 0 0 0 64 880 + 7 2 loop2 36 0 216 4 0 0 0 0 0 4 4 + 7 6 loop6 0 0 0 0 0 0 0 0 0 0 0 + 7 7 loop7 0 0 0 0 0 0 0 0 0 0 0 + 251 2 zram2 27487 0 219896 188 79953 0 639624 1640 0 1828 1828 + 251 3 zram3 27348 0 218784 152 79952 0 639616 1960 0 2060 2104 +``` +All zram devices starts with `251` number and all loop devices starts with `7`. +So, to disable performance metrics for all loop devices you could add `performance metrics for disks with major 7 = no` to `[plugin:proc:/proc/diskstats]` section. +``` +[plugin:proc:/proc/diskstats] + performance metrics for disks with major 7 = no +``` + diff --git a/collectors/proc.plugin/ipc.c b/collectors/proc.plugin/ipc.c new file mode 100644 index 000000000..6c6bee519 --- /dev/null +++ b/collectors/proc.plugin/ipc.c @@ -0,0 +1,263 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "plugin_proc.h" + +#include +#include +#include + + +#ifndef SEMVMX +#define SEMVMX 32767 /* <= 32767 semaphore maximum value */ +#endif + +/* Some versions of libc only define IPC_INFO when __USE_GNU is defined. */ +#ifndef IPC_INFO +#define IPC_INFO 3 +#endif + +struct ipc_limits { + uint64_t shmmni; /* max number of segments */ + uint64_t shmmax; /* max segment size */ + uint64_t shmall; /* max total shared memory */ + uint64_t shmmin; /* min segment size */ + + int semmni; /* max number of arrays */ + int semmsl; /* max semaphores per array */ + int semmns; /* max semaphores system wide */ + int semopm; /* max ops per semop call */ + unsigned int semvmx; /* semaphore max value (constant) */ + + int msgmni; /* max queues system wide */ + size_t msgmax; /* max size of message */ + int msgmnb; /* default max size of queue */ +}; + +struct ipc_status { + int semusz; /* current number of arrays */ + int semaem; /* current semaphores system wide */ +}; + +/* + * The last arg of semctl is a union semun, but where is it defined?

You just need to remember to include 5 major things: +- **ORDER** global list +- **CHART** global dictionary +- **Service** class +- **_get_data** method +- all code needs to be compatible with Python 2 (**≥ 2.7**) *and* 3 (**≥ 3.1**) + +If you plan to submit the module in a PR, make sure and go through the [PR checklist for new modules](https://github.com/netdata/netdata/wiki/New-Module-PR-Checklist) beforehand to make sure you have updated all the files you need to. + +### Global variables `ORDER` and `CHART` + +`ORDER` list should contain the order of chart ids. Example: +```py +ORDER = ['first_chart', 'second_chart', 'third_chart'] +``` + +`CHART` dictionary is a little bit trickier. It should contain the chart definition in following format: +```py +CHART = { + id: { + 'options': [name, title, units, family, context, charttype], + 'lines': [ + [unique_dimension_name, name, algorithm, multiplier, divisor] + ]} +``` + +All names are better explained in the [External Plugins](../) section. +Parameters like `priority` and `update_every` are handled by `python.d.plugin`. + +### `Service` class + +Every module needs to implement its own `Service` class. This class should inherit from one of the framework classes: + +- `SimpleService` +- `UrlService` +- `SocketService` +- `LogService` +- `ExecutableService` + +Also it needs to invoke the parent class constructor in a specific way as well as assign global variables to class variables. + +Simple example: +```py +from base import UrlService +class Service(UrlService): + def __init__(self, configuration=None, name=None): + UrlService.__init__(self, configuration=configuration, name=name) + self.order = ORDER + self.definitions = CHARTS +``` + +### `_get_data` collector/parser + +This method should grab raw data from `_get_raw_data`, parse it, and return a dictionary where keys are unique dimension names or `None` if no data is collected. + +Example: +```py +def _get_data(self): + try: + raw = self._get_raw_data().split(" ") + return {'active': int(raw[2])} + except (ValueError, AttributeError): + return None +``` + +More about framework classes +============================ + +Every framework class has some user-configurable variables which are specific to this particular class. Those variables should have default values initialized in the child class constructor. + +If module needs some additional user-configurable variable, it can be accessed from the `self.configuration` list and assigned in constructor or custom `check` method. Example: +```py +def __init__(self, configuration=None, name=None): + UrlService.__init__(self, configuration=configuration, name=name) + try: + self.baseurl = str(self.configuration['baseurl']) + except (KeyError, TypeError): + self.baseurl = "http://localhost:5001" +``` + +Classes implement `_get_raw_data` which should be used to grab raw data. This method usually returns a list of strings. + +### `SimpleService` + +_This is last resort class, if a new module cannot be written by using other framework class this one can be used._ + +_Example: `mysql`, `sensors`_ + +It is the lowest-level class which implements most of module logic, like: +- threading +- handling run times +- chart formatting +- logging +- chart creation and updating + +### `LogService` + +_Examples: `apache_cache`, `nginx_log`_ + +_Variable from config file_: `log_path`. + +Object created from this class reads new lines from file specified in `log_path` variable. It will check if file exists and is readable. Also `_get_raw_data` returns list of strings where each string is one line from file specified in `log_path`. + +### `ExecutableService` + +_Examples: `exim`, `postfix`_ + +_Variable from config file_: `command`. + +This allows to execute a shell command in a secure way. It will check for invalid characters in `command` variable and won't proceed if there is one of: +- '&' +- '|' +- ';' +- '>' +- '<' + +For additional security it uses python `subprocess.Popen` (without `shell=True` option) to execute command. Command can be specified with absolute or relative name. When using relative name, it will try to find `command` in `PATH` environment variable as well as in `/sbin` and `/usr/sbin`. + +`_get_raw_data` returns list of decoded lines returned by `command`. + +### UrlService + +_Examples: `apache`, `nginx`, `tomcat`_ + +_Variables from config file_: `url`, `user`, `pass`. + +If data is grabbed by accessing service via HTTP protocol, this class can be used. It can handle HTTP Basic Auth when specified with `user` and `pass` credentials. + +`_get_raw_data` returns list of utf-8 decoded strings (lines). + +### SocketService + +_Examples: `dovecot`, `redis`_ + +_Variables from config file_: `unix_socket`, `host`, `port`, `request`. + +Object will try execute `request` using either `unix_socket` or TCP/IP socket with combination of `host` and `port`. This can access unix sockets with SOCK_STREAM or SOCK_DGRAM protocols and TCP/IP sockets in version 4 and 6 with SOCK_STREAM setting. + +Sockets are accessed in non-blocking mode with 15 second timeout. + +After every execution of `_get_raw_data` socket is closed, to prevent this module needs to set `_keep_alive` variable to `True` and implement custom `_check_raw_data` method. + +`_check_raw_data` should take raw data and return `True` if all data is received otherwise it should return `False`. Also it should do it in fast and efficient way. \ No newline at end of file diff --git a/collectors/python.d.plugin/adaptec_raid/Makefile.inc b/collectors/python.d.plugin/adaptec_raid/Makefile.inc new file mode 100644 index 000000000..716cdb235 --- /dev/null +++ b/collectors/python.d.plugin/adaptec_raid/Makefile.inc @@ -0,0 +1,13 @@ +# SPDX-License-Identifier: GPL-3.0-or-later + +# THIS IS NOT A COMPLETE Makefile +# IT IS INCLUDED BY ITS PARENT'S Makefile.am +# IT IS REQUIRED TO REFERENCE ALL FILES RELATIVE TO THE PARENT + +# install these files +dist_python_DATA += adaptec_raid/adaptec_raid.chart.py +dist_pythonconfig_DATA += adaptec_raid/adaptec_raid.conf + +# do not install these files, but include them in the distribution +dist_noinst_DATA += adaptec_raid/README.md adaptec_raid/Makefile.inc + diff --git a/collectors/python.d.plugin/adaptec_raid/README.md b/collectors/python.d.plugin/adaptec_raid/README.md new file mode 100644 index 000000000..499dc9190 --- /dev/null +++ b/collectors/python.d.plugin/adaptec_raid/README.md @@ -0,0 +1,46 @@ +# adaptec raid + +Module collects logical and physical devices health metrics. + +**Requirements:** +* `arcconf` program +* `sudo` program +* `netdata` user needs to be able to sudo the `arcconf` program without password + +To grab stats it executes: + * `sudo -n arcconf GETCONFIG 1 LD` + * `sudo -n arcconf GETCONFIG 1 PD` + + +It produces: + +1. **Logical Device Status** + +2. **Physical Device State** + +3. **Physical Device S.M.A.R.T warnings** + +4. **Physical Device Temperature** + +### prerequisite +This module uses `arcconf` which can only be executed by root.

Applications are sending metrics to it, usually via non-blocking UDP communication, and statsd servers collect these metrics, perform a few simple calculations on them and push them to backend time-series databases. + +There is a [plethora of client libraries](https://github.com/etsy/statsd/wiki#client-implementations) for embedding statsd metrics to any application framework. This makes statsd quite popular for custom application metrics. + +## netdata statsd + +netdata is a fully featured statsd server. It can collect statsd formatted metrics, visualize them on its dashboards, stream them to other netdata servers or archive them to backend time-series databases. + +netdata statsd is inside netdata (an internal plugin, running inside the netdata daemon), it is configured via `netdata.conf` and by-default listens on standard statsd ports (tcp and udp 8125 - yes, netdata statsd server supports both tcp and udp at the same time). + +Since statsd is embedded in netdata, it means you now have a statsd server embedded on all your servers. So, the application can send its metrics to `localhost:8125`. This provides a distributed statsd implementation. + +netdata statsd is fast. It can collect more than **1.200.000 metrics per second** on modern hardware, more than **200Mbps of sustained statsd traffic**, using 1 CPU core (yes, it is single threaded - actually double-threaded, one thread collects metrics, another one updates the charts from the collected data). + +## metrics supported by netdata + +netdata fully supports the statsd protocol. All statsd client libraries can be used with netdata too. + +- **Gauges** + + The application sends `name:value|g`, where `value` is any **decimal/fractional** number, statsd reports the latest value collected and the number of times it was updated (events). + + The application may increment or decrement a previous value, by setting the first character of the value to ` + ` or ` - ` (so, the only way to set a gauge to an absolute negative value, is to first set it to zero). + + Sampling rate is supported (check below). + + When a gauge is not collected and the setting is not to show gaps on the charts (the default), the last value will be shown, until a data collection event changes it. + +- **Counters** and **Meters** + + The application sends `name:value|c`, `name:value|C` or `name:value|m`, where `value` is a positive or negative **integer** number of events occurred, statsd reports the **rate** and the number of times it was updated (events). + + `:value` can be omitted and statsd will assume it is `1`. `|c`, `|C` and `|m` can be omitted an statsd will assume it is `|m`. So, the application may send just `name` and statsd will parse it as `name:1|m`. + + For counters use `|c` (esty/statsd compatible) or `|C` (brubeck compatible), for meters use `|m`. + + Sampling rate is supported (check below). + + When a counter or meter is not collected and the setting is not to show gaps on the charts (the default), zero will be shown, until a data collection event changes it. + +- **Timers** and **Histograms** + + The application sends `name:value|ms` or `name:value|h`, where ` value` is any **decimal/fractional** number, statsd reports **min**, **max**, **average**, **sum**, **95th percentile**, **median** and **standard deviation** and the total number of times it was updated (events). + + For timers use `|ms`, or histograms use `|h`. The only difference between the two, is the `units` of the charts (timers report milliseconds). + + Sampling rate is supported (check below). + + When a timer or histogram is not collected and the setting is not to show gaps on the charts (the default), zero will be shown, until a data collection event changes it. + +- **Sets** + + The application sends `name:value|s`, where `value` is anything (**number or text**, leading and trailing spaces are removed), statsd reports the number of unique values sent and the number of times it was updated (events). + + Sampling rate is **not** supported for Sets. `value` is always considered text. + + When a set is not collected and the setting is not to show gaps on the charts (the default), zero will be shown, until a data collection event changes it. + +#### Sampling Rates + +The application may append `|@sampling_rate`, where `sampling_rate` is a number from `0.0` to `1.0`, to have statsd extrapolate the value, to predict to total for the whole period. So, if the application reports to statsd a value for 1/10th of the time, it can append `|@0.1` to the metrics it sends to statsd. + +#### Overlapping metrics + +netdata statsd maintains different indexes for each of the types supported. This means the same metric `name` may exist under different types concurrently. + +#### Multiple metrics per packet + +netdata accepts multiple metrics per packet if each is terminated with `\n`. + +#### TCP packets + +netdata listens for both TCP and UDP packets. For TCP though, is it important to always append `\n` on each metric. netdata uses this to detect if a metric is split into multiple TCP packets. On disconnect, even the remaining (non terminated with `\n`) buffer, is processed. + +#### UDP packets + +When sending multiple packets over UDP, it is important not to exceed the network MTU (usually 1500 bytes minus a few bytes for the headers). netdata will accept UDP packets up to 9000 bytes, but the underlying network will not exceed MTU. + +## configuration + +This is the statsd configuration at `/etc/netdata/netdata.conf`: + +``` +[statsd] + # enabled = yes + # decimal detail = 1000 + # update every (flushInterval) = 1 + # udp messages to process at once = 10 + # create private charts for metrics matching = * + # max private charts allowed = 200 + # max private charts hard limit = 1000 + # private charts memory mode = save + # private charts history = 3996 + # histograms and timers percentile (percentThreshold) = 95.00000 + # add dimension for number of events received = yes + # gaps on gauges (deleteGauges) = no + # gaps on counters (deleteCounters) = no + # gaps on meters (deleteMeters) = no + # gaps on sets (deleteSets) = no + # gaps on histograms (deleteHistograms) = no + # gaps on timers (deleteTimers) = no + # listen backlog = 4096 + # default port = 8125 + # bind to = udp:localhost:8125 tcp:localhost:8125 +``` + +### statsd main config options +- `enabled = yes|no` + + controls if statsd will be enabled for this netdata. The default is enabled. + +- `default port = 8125` + + controls the port statsd will use. This is the default, since the next line, allows defining ports too. + +- `bind to = udp:localhost tcp:localhost` + + is a space separated list of IPs and ports to listen to. The format is `PROTOCOL:IP:PORT` - if `PORT` is omitted, the `default port` will be used. If `IP` is IPv6, it needs to be enclosed in `[]`. `IP` can also be ` * ` (to listen on all IPs) or even a hostname. + +- `update every (flushInterval) = 1` seconds, controls the frequency statsd will push the collected metrics to netdata charts. + +- `decimal detail = 1000` controls the number of fractional digits in gauges and histograms. netdata collects metrics using signed 64 bit integers and their fractional detail is controlled using multipliers and divisors. This setting is used to multiply all collected values to convert them to integers and is also set as the divisors, so that the final data will be a floating point number with this fractional detail (1000 = X.0 - X.999, 10000 = X.0 - X.9999, etc). + +The rest of the settings are discussed below. + +## statsd charts + +netdata can visualize statsd collected metrics in 2 ways: + +1. Each metric gets its own **private chart**. This is the default and does not require any configuration (although there are a few options to tweak). + +2. **Synthetic charts** can be created, combining multiple metrics, independently of their metric types. For this type of charts, special configuration is required, to define the chart title, type, units, its dimensions, etc. + +### private metric charts + +Private charts are controlled with `create private charts for metrics matching = *`. This setting accepts a space separated list of simple patterns (use `*` as wildcard, prepend a pattern with `!` for a negative match, the order of patterns is important). + +So to render charts for all `myapp.*` metrics, except `myapp.*.badmetric`, use: + +``` +create private charts for metrics matching = !myapp.*.badmetric myapp.* +``` + +The default is to render private charts for all metrics. + +The `memory mode` of the round robin database and the `history` of private metric charts are controlled with `private charts memory mode` and `private charts history`. The defaults for both settings is to use the global netdata settings. So, you need to edit them only when you want statsd to use different settings compared to the global ones. + +If you have thousands of metrics, each with its own private chart, you may notice that your web browser becomes slow when you view the netdata dashboard (this is a web browser issue we need to address at the netdata UI). So, netdata has a protection to stop creating charts when `max private charts allowed = 200` (soft limit) is reached. + +The metrics above this soft limit are still processed by netdata and will be available to be sent to backend time-series databases, up to `max private charts hard limit = 1000`. So, between 200 and 1000 charts, netdata will still generate charts, but they will automatically be created with `memory mode = none` (netdata will not maintain a database for them). These metrics will be sent to backend time series databases, if the backend configuration is set to `as collected`. + +Metrics above the hard limit are still collected, but they can only be used in synthetic charts (once a metric is added to chart, it will be sent to backend servers too). + +Example private charts (automatically generated without any configuration): + +#### counters + +- Scope: **count the events of something** (e.g. number of file downloads) +- Format: `name:INTEGER|c` or `name:INTEGER|C` or `name|c` +- statsd increments the counter by the `INTEGER` number supplied (positive, or negative). + +![image](https://cloud.githubusercontent.com/assets/2662304/26131553/4a26d19c-3aa3-11e7-94e8-c53b5ed6ebc3.png) + +#### gauges + +- Scope: **report the value of something** (e.g. cache memory used by the application server) +- Format: `name:FLOAT|g` +- statsd remembers the last value supplied, and can increment or decrement the latest value if `FLOAT` begins with ` + ` or ` - `. + +![image](https://cloud.githubusercontent.com/assets/2662304/26131575/5d54e6f0-3aa3-11e7-9099-bc4440cd4592.png) + +#### histograms + +- Scope: **statistics on a size of events** (e.g. statistics on the sizes of files downloaded) +- Format: `name:FLOAT|h` +- statsd maintains a list of all the values supplied and provides statistics on them. + +![image](https://cloud.githubusercontent.com/assets/2662304/26131587/704de72a-3aa3-11e7-9ea9-0d2bb778c150.png) + +The same chart with `sum` unselected, to show the detail of the dimensions supported: +![image](https://cloud.githubusercontent.com/assets/2662304/26131598/8076443a-3aa3-11e7-9ffa-ea535aee9c9f.png) + +#### meters + +This is identical to `counter`. + +- Scope: **count the events of something** (e.g. number of file downloads) +- Format: `name:INTEGER|m` or `name|m` or just `name` +- statsd increments the counter by the `INTEGER` number supplied (positive, or negative). + +![image](https://cloud.githubusercontent.com/assets/2662304/26131605/8fdf5a06-3aa3-11e7-963f-7ecf207d1dbc.png) + +#### sets + +- Scope: **count the unique occurrences of something** (e.g. unique filenames downloaded, or unique users that downloaded files) +- Format: `name:TEXT|s` +- statsd maintains a unique index of all values supplied, and reports the unique entries in it. + +![image](https://cloud.githubusercontent.com/assets/2662304/26131612/9eaa7b1a-3aa3-11e7-903b-d881e9a35be2.png) + +#### timers + +- Scope: **statistics on the duration of events** (e.g. statistics for the duration of file downloads) +- Format: `name:FLOAT|ms` +- statsd maintains a list of all the values supplied and provides statistics on them. + +![image](https://cloud.githubusercontent.com/assets/2662304/26131620/acbea6a4-3aa3-11e7-8bdd-4a8996847767.png) + +The same chart with the `sum` unselected: +![image](https://cloud.githubusercontent.com/assets/2662304/26131629/bc34f2d2-3aa3-11e7-8a07-f2fc94ba4352.png) + + + +### synthetic statsd charts + +Using synthetic charts, you can create dedicated sections on the dashboard to render the charts. You can control everything: the main menu, the submenus, the charts, the dimensions on each chart, etc. + +Synthetic charts are organized in + +- **applications** (i.e. entries at the main menu of the netdata dashboard) +- **charts for each application** (grouped in families - i.e. submenus at the dashboard menu) +- **statsd metrics for each chart** (i.e. dimensions of the charts) + +For each application you need to create a `.conf` file in `/etc/netdata/statsd.d`. + +So, to create the statsd application `myapp`, you can create the file `/etc/netdata/statsd.d/myapp.conf`, with this content: + +``` +[app] + name = myapp + metrics = myapp.* + private charts = no + gaps when not collected = no + memory mode = ram + history = 60 + +[dictionary] + m1 = metric1 + m2 = metric2 + +# replace 'mychart' with the chart id +# the chart will be named: myapp.mychart +[mychart] + name = mychart + title = my chart title + family = my family + context = chart.context + units = tests/s + priority = 91000 + type = area + dimension = myapp.metric1 m1 + dimension = myapp.metric2 m2 +``` + +Using the above configuration `myapp` should get its own section on the dashboard, having one chart with 2 dimensions. + +`[app]` starts a new application definition. The supported settings in this section are: + +- `name` defines the name of the app. +- `metrics` is a netdata simple pattern (space separated patterns, using `*` for wildcard, possibly starting with `!` for negative match). This pattern should match all the possible statsd metrics that will be participating in the application `myapp`. +- `private charts = yes|no`, enables or disables private charts for the metrics matched. +- `gaps when not collected = yes|no`, enables or disables gaps on the charts of the application, when metrics are not collected. +- `memory mode` sets the memory mode for all charts of the application. The default is the global default for netdata (not the global default for statsd private charts). +- `history` sets the size of the round robin database for this application. The default is the global default for netdata (not the global default for statsd private charts). + +`[dictionary]` defines name-value associations. These are used to renaming metrics, when added to synthetic charts. Metric names are also defined at each `dimension` line. However, using the dictionary dimension names can be declared globally, for each app and is the only way to rename dimensions when using patterns. Of course the dictionary can be empty or missing. + +Then, you can add any number of charts. Each chart should start with `[id]`. The chart will be called `app_name.id`. `family` controls the submenu on the dashboard. `context` controls the alarm templates. `priority` controls the ordering of the charts on the dashboard. The rest of the settings are informational. + +You can add any number of metrics to a chart, using `dimension` lines. These lines accept 5 space separated parameters: + +1. the metric name, as it is collected (it has to be matched by the `metrics = ` pattern of the app) +2. the dimension name, as it should be shown on the chart +3. an optional selector (type) of the value to shown (see below) +4. an optional multiplier +5. an optional divider +6. optional flags, space separated and enclosed in quotes. All the external plugins `DIMENSION` flags can be used. Currently the only usable flag is `hidden`, to add the dimension, but not show it on the dashboard. This is usually needed to have the values available for percentage calculation, or use them in alarms. + +So, the format is this: +``` +dimension = [pattern] METRIC NAME TYPE MULTIPLIER DIVIDER OPTIONS +``` + +`pattern` is a keyword. When set, `METRIC` is expected to be a netdata simple pattern that will be used to match all the statsd metrics to be added to the chart. So, `pattern` automatically matches any number of statsd metrics, all of which will be added as separate chart dimensions. + +`TYPE`, `MUTLIPLIER`, `DIVIDER` and `OPTIONS` are optional. + +`TYPE` can be: + +- `events` to show the number of events received by statsd for this metric +- `last` to show the last value, as calculated at the flush interval of the metric (the default) + +Then for histograms and timers the following types are also supported: + +- `min`, show the minimum value +- `max`, show the maximum value +- `sum`, show the sum of all values +- `average` (same as `last`) +- `percentile`, show the 95th percentile (or any other percentile, as configured at statsd global config) +- `median`, show the median of all values (i.e. sort all values and get the middle value) +- `stddev`, show the standard deviation of the values + +#### example synthetic charts + +statsd metrics: `foo` and `bar`. + +Contents of file `/etc/netdata/stats.d/foobar.conf`: + +``` +[app] + name = foobarapp + metrics = foo bar + private charts = yes + +[foobar_chart1] + title = Hey, foo and bar together + family = foobar_family + context = foobarapp.foobars + units = foobars + type = area + dimension = foo 'foo me' last 1 1 + dimension = bar 'bar me' last 1 1 +``` + +I sent to statsd: `foo:10|g` and `bar:20|g`. + +I got these private charts: + +![screenshot from 2017-08-03 23-28-19](https://user-images.githubusercontent.com/2662304/28942295-7c3a73a8-78a3-11e7-88e5-a9a006bb7465.png) + +and this synthetic chart: + +![screenshot from 2017-08-03 23-29-14](https://user-images.githubusercontent.com/2662304/28942317-958a2c68-78a3-11e7-853f-32850141dd36.png) + +#### dictionary to name dimensions + +The `[dictionary]` section accepts any number of `name = value` pairs. + +netdata uses this dictionary as follows: + +1. When a `dimension` has a non-empty `NAME`, that name is looked up at the dictionary. + +2. If the above lookup gives nothing, or the `dimension` has an empty `NAME`, the original statsd metric name is looked up at the dictionary. + +3. If any of the above succeeds, netdata uses the `value` of the dictionary, to set the name of the dimension. The dimensions will have as ID the original statsd metric name, and as name, the dictionary value. + +So, you can use the dictionary in 2 ways: + +1. set `dimension = myapp.metric1 ''` and have at the dictionary `myapp.metric1 = metric1 name` +2. set `dimension = myapp.metric1 'm1'` and have at the dictionary `m1 = metric1 name` + +In both cases, the dimension will be added with ID `myapp.metric1` and will be named `metric1 name`. So, in alarms you can use either of the 2 as `${myapp.metric1}` or `${metric1 name}`. + +> keep in mind that if you add multiple times the same statsd metric to a chart, netdata will append `TYPE` to the dimension ID, so `myapp.metric1` will be added as `myapp.metric1_last` or `myapp.metric1_events`, etc. If you add multiple times the same metric with the same `TYPE` to a chart, netdata will also append an incremental counter to the dimension ID, i.e. `myapp.metric1_last1`, `myapp.metric1_last2`, etc. + +#### dimension patterns + +netdata allows adding multiple dimensions to a chart, by matching the statsd metrics with a netdata simple pattern. + +Assume we have an API that provides statsd metrics for each response code per method it supports, like these: + +``` +myapp.api.get.200 +myapp.api.get.400 +myapp.api.get.500 +myapp.api.del.200 +myapp.api.del.400 +myapp.api.del.500 +myapp.api.post.200 +myapp.api.post.400 +myapp.api.post.500 +myapp.api.all.200 +myapp.api.all.400 +myapp.api.all.500 +``` + +To add all response codes of `myapp.api.get` to a chart use this: + +``` +[api_get_responses] + ... + dimension = pattern 'myapp.api.get.* '' last 1 1 +``` + +The above will add dimension named `200`, `400` and `500` (yes, netdata extracts the wildcarded part of the metric name - so the dimensions will be named with whatever the `*` matched). You can rename the dimensions with this: + +``` +[dictionary] + get.200 = 200 ok + get.400 = 400 bad request + get.500 = 500 cannot connect to db + +[api_get_responses] + ... + dimension = pattern 'myapp.api.get.* 'get.' last 1 1 +``` + +Note that we added a `NAME` to the dimension line with `get.`. This is prefixed to the wildcarded part of the metric name, to compose the key for looking up the dictionary. So `500` became `get.500` which was looked up to the dictionary to find value `500 cannot connect to db`. This way we can have different dimension names, for each of the API methods (i.e. `get.500 = 500 cannot connect to db` while `post.500 = 500 cannot write to disk`). + +To add all API methods to a chart, do this: + +``` +[ok_by_method] + ... + dimension = pattern 'myapp.api.*.200 '' last 1 1 +``` + +The above will add `get`, `post`, `del` and `all` to the chart. + +If `all` is not wanted (a `stacked` chart does not need the `all` dimension, since the sum of the dimensions provides the total), the line should be: + +``` +[ok_by_method] + ... + dimension = pattern '!myapp.api.all.* myapp.api.*.200 '' last 1 1 +``` + +With the above, all methods except `all` will be added to the chart. + +To automatically rename the methods, use this: + +``` +[dictionary] + method.get = GET + method.post = ADD + method.del = DELETE + +[ok_by_method] + ... + dimension = pattern '!myapp.api.all.* myapp.api.*.200 'method.' last 1 1 +``` + +Using the above, the dimensions will be added as `GET`, `ADD` and `DELETE`. + + +## interpolation + +~~If you send just one value to statsd, you will notice that the chart is created but no value is shown. The reason is that netdata interpolates all values at second boundaries. For incremental values (`counters` and `meters` in statsd terminology), if you send 10 at 00:00:00.500, 20 at 00:00:01.500 and 30 at 00:00:02.500, netdata will show 15 at 00:00:01 and 25 at 00:00:02.~~ + +~~This interpolation is automatic and global in netdata for all charts, for incremental values. This means that for the chart to start showing values you need to send 2 values across 2 flush intervals.~~ + +~~(although this is required for incremental values, netdata allows mixing incremental and absolute values on the same charts, so this little limitation [i.e. 2 values to start visualization], is applied on all netdata dimensions).~~ + +(statsd metrics do not loose their first data collection due to interpolation anymore - fixed with [PR #2411](https://github.com/netdata/netdata/pull/2411)) + +## sending statsd metrics from shell scripts + +You can send/update statsd metrics from shell scripts. You can use this feature, to visualize in netdata automated jobs you run on your servers. + +The command you need to run is: + +```sh +echo "NAME:VALUE|TYPE" | nc -u --send-only localhost 8125 +``` + +Where: + +- `NAME` is the metric name +- `VALUE` is the value for that metric (**gauges** `|g`, **timers** `|ms` and **histograms** `|h` accept decimal/fractional numbers, **counters** `|c` and **meters** `|m` accept integers, **sets** `|s` accept anything) +- `TYPE` is one of `g`, `ms`, `h`, `c`, `m`, `s` to select the metric type. + +So, to set `metric1` as gauge to value `10`, use: + +```sh +echo "metric1:10|g" | nc -u --send-only localhost 8125 +``` + +To increment `metric2` by `10`, as a counter, use: + +```sh +echo "metric2:10|c" | nc -u --send-only localhost 8125 +``` + +You can send multiple metrics like this: + +```sh +# send multiple metrics via UDP +printf "metric1:10|g\nmetric2:10|c\n" | nc -u --send-only localhost 8125 +``` + +Remember, for UDP communication each packet should not exceed the MTU. So, if you plan to push too many metrics at once, prefer TCP communication: + +```sh +# send multiple metrics via TCP +printf "metric1:10|g\nmetric2:10|c\n" | nc --send-only localhost 8125 +``` + +You can also use this little function to take care of all the details: + +```sh +#!/usr/bin/env bash + +STATSD_HOST="localhost" +STATSD_PORT="8125" +statsd() { + local udp="-u" all="${*}" + + # if the string length of all parameters given is above 1000, use TCP + [ "${#all}" -gt 1000 ] && udp= + + while [ ! -z "${1}" ] + do + printf "${1}\n" + shift + done | nc ${udp} --send-only ${STATSD_HOST} ${STATSD_PORT} || return 1 + + return 0 +} +``` + +You can use it like this: + +```sh +# first, source it in your script +source statsd.sh + +# then, at any point: +statsd "metric1:10|g" "metric2:10|c" ... +``` + +The function is smart enough to call `nc` just once and pass all the metrics to it. It will also automatically switch to TCP if the metrics to send are above 1000 bytes. diff --git a/collectors/statsd.plugin/example.conf b/collectors/statsd.plugin/example.conf new file mode 100644 index 000000000..2c7de6c7b --- /dev/null +++ b/collectors/statsd.plugin/example.conf @@ -0,0 +1,64 @@ +# statsd synthetic charts configuration + +# You can add many .conf files in /etc/netdata/statsd.d/, +# one for each of your apps. + +# start a new app - you can add many apps in the same file +[app] + # give a name for this app + # this controls the main menu on the dashboard + # and will be the prefix for all charts of the app + name = myexampleapp + + # match all the metrics of the app + metrics = myexampleapp.* + + # shall private charts of these metrics be created? + private charts = no + + # shall gaps be shown when metrics are not collected? + gaps when not collected = no + + # the memory mode for the charts of this app: none|map|save + # the default is to use the global memory mode + #memory mode = ram + + # the history size for the charts of this app, in seconds + # the default is to use the global history + #history = 3600 + +# create a chart +# this is its id - the chart will be named myexampleapp.myexamplechart +[myexamplechart] + # a name for the chart, similar to the id (2 names for each chart) + name = myexamplechart + + # the chart title + title = my chart title + + # the submenu of the dashboard + family = my family + + # the context for alarm templates + context = chart.context + + # the units of the chart + units = tests/s + + # the sorting priority of the chart on the dashboard + priority = 91000 + + # the type of chart to create: line | area | stacked + type = area + + # one or more dimensions for the chart + # type = events | last | min | max | sum | average | percentile | median | stddev + # events = the number of events for this metric + # last = the last value collected + # all the others are only valid for histograms and timers + dimension = myexampleapp.metric1 avg average 1 1 + dimension = myexampleapp.metric1 lower min 1 1 + dimension = myexampleapp.metric1 upper max 1 1 + dimension = myexampleapp.metric2 other last 1 1 + +# You can add as many charts as needed diff --git a/collectors/statsd.plugin/statsd.c b/collectors/statsd.plugin/statsd.c new file mode 100644 index 000000000..c92bfd1c2 --- /dev/null +++ b/collectors/statsd.plugin/statsd.c @@ -0,0 +1,2556 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "statsd.h" + +#define STATSD_CHART_PREFIX "statsd" + +#define PLUGIN_STATSD_NAME "statsd.plugin" + +// -------------------------------------------------------------------------------------- + +// #define STATSD_MULTITHREADED 1 + +#ifdef STATSD_MULTITHREADED +// DO NOT ENABLE MULTITHREADING - IT IS NOT WELL TESTED +#define STATSD_AVL_TREE avl_tree_lock +#define STATSD_AVL_INSERT avl_insert_lock +#define STATSD_AVL_SEARCH avl_search_lock +#define STATSD_AVL_INDEX_INIT { .avl_tree = { NULL, statsd_metric_compare }, .rwlock = AVL_LOCK_INITIALIZER } +#define STATSD_FIRST_PTR_MUTEX netdata_mutex_t first_mutex +#define STATSD_FIRST_PTR_MUTEX_INIT .first_mutex = NETDATA_MUTEX_INITIALIZER +#define STATSD_FIRST_PTR_MUTEX_LOCK(index) netdata_mutex_lock(&((index)->first_mutex)) +#define STATSD_FIRST_PTR_MUTEX_UNLOCK(index) netdata_mutex_unlock(&((index)->first_mutex)) +#define STATSD_DICTIONARY_OPTIONS DICTIONARY_FLAG_DEFAULT +#else +#define STATSD_AVL_TREE avl_tree +#define STATSD_AVL_INSERT avl_insert +#define STATSD_AVL_SEARCH avl_search +#define STATSD_AVL_INDEX_INIT { .root = NULL, .compar = statsd_metric_compare } +#define STATSD_FIRST_PTR_MUTEX +#define STATSD_FIRST_PTR_MUTEX_INIT +#define STATSD_FIRST_PTR_MUTEX_LOCK(index) +#define STATSD_FIRST_PTR_MUTEX_UNLOCK(index) +#define STATSD_DICTIONARY_OPTIONS DICTIONARY_FLAG_SINGLE_THREADED +#endif + +#define STATSD_DECIMAL_DETAIL 1000 // floating point values get multiplied by this, with the same divisor + +// -------------------------------------------------------------------------------------------------------------------- +// data specific to each metric type + +typedef struct statsd_metric_gauge { + LONG_DOUBLE value;

It is somewhat complex, because a state +machine was needed to keep track of all the `tc` classes, including the pseudo classes tc +dynamically creates. + +## Motivation + +One category of metrics missing in Linux monitoring, is bandwidth consumption for each open +socket (inbound and outbound traffic). So, you cannot tell how much bandwidth your web server, +your database server, your backup, your ssh sessions, etc are using. + +To solve this problem, the most *adventurous* Linux monitoring tools install kernel modules to +capture all traffic, analyze it and provide reports per application. A lot of work, CPU intensive +and with a great degree of risk (due to the kernel modules involved which might affect the +stability of the whole system). Not to mention that such solutions are probably better suited +for a core linux router in your network. + +Others use NFACCT, the netfilter accounting module which is already part of the Linux firewall. +However, this would require configuring a firewall on every system you want to measure bandwidth. + +QoS monitoring attempts to solve this in a much cleaner way. + +## Introduction to QoS + +One of the features the Linux kernel has, but it is rarely used, is its ability to +**apply QoS on traffic**. Even most interesting is that it can apply QoS to **both inbound and +outbound traffic**. + +QoS is about 2 features: + +1. **Classify traffic** + + Classification is the process of organizing traffic in groups, called **classes**. + Classification can evaluate every aspect of network packets, like source and destination ports, + source and destination IPs, netfilter marks, etc. + + When you classify traffic, you just assign a label to it. For example **I call `web server` + traffic, the traffic from my server's tcp/80, tcp/443 and to my server's tcp/80, tcp/443, + while I call `web surfing` all other tcp/80 and tcp/443 traffic**. You can use any combinations + you like. There is no limit. + +2. **Apply traffic shaping rules to these classes** + + Traffic shaping is used to control how network interface bandwidth should be shared among the + classes. Of course we are not interested for this feature to just monitor the traffic. + Classification will be enough for monitoring everything. + +The key reasons of applying QoS on all servers (even cloud ones) are: + + - **ensure administrative tasks (like ssh, dns, etc) will always have a small but guaranteed + bandwidth.** QoS can guarantee that services like ssh, dns, ntp, etc will always have a small + supply of bandwidth. So, no matter what happens, you will be able to ssh to your server and + DNS will always work. + + - **ensure other administrative tasks will not monopolize all the available bandwidth.** + Services like backups, file copies, database dumps, etc can easily monopolize all the + available bandwidth. It is common for example a nightly backup, or a huge file transfer + to negatively influence the end-user experience. QoS can fix that. + + - **ensure each end-user connection will get a fair cut of the available bandwidth.** + Several QoS queuing disciplines in Linux do this automatically, without any configuration from you. + The result is that new sockets are favored over older ones, so that users will get a snappier + experience, while others are transferring large amounts of traffic. + + - **protect the servers from DDoS attacks.** + When your system is under a DDoS attack, it will get a lot more bandwidth compared to the one it + can handle and probably your applications will crash. Setting a limit on the inbound traffic using + QoS, will protect your servers (throttle the requests) and depending on the size of the attack may + allow your legitimate users to access the server, while the attack is taking place. + + +Once **traffic classification** is applied, netdata can visualize the bandwidth consumption per +class in real-time (no configuration is needed for netdata - it will figure it out). + +QoS, is extremely light. You will configure it once, and this is it. It will not bother you again +and it will not use any noticeable CPU resources, especially on application and database servers. + +## QoS in Linux? Have you lost your mind? + +Yes I know... but no, I have not! + +Of course, `tc` is probably **the most undocumented, complicated and unfriendly** command in Linux. + +For example, for matching a simple port range in `tc`, e.g. all the high ports, from 1025 to 65535 +inclusive, you have to match these: + +``` +1025/0xffff 1026/0xfffe 1028/0xfffc 1032/0xfff8 1040/0xfff0 +1056/0xffe0 1088/0xffc0 1152/0xff80 1280/0xff00 1536/0xfe00 +2048/0xf800 4096/0xf000 8192/0xe000 16384/0xc000 32768/0x8000 +``` + +I know what you are thinking right now! **And I agree!** + +This is why I wrote **[FireQOS](https://firehol.org/tutorial/fireqos-new-user/)**, a tool to +simplify QoS management in Linux. + +The **[FireHOL](https://firehol.org/)** package already distributes **[FireQOS](https://firehol.org/tutorial/fireqos-new-user/)**. +Check the **[FireQOS tutorial](https://firehol.org/tutorial/fireqos-new-user/)** +to learn how to write your own QoS configuration. + +With **[FireQOS](https://firehol.org/tutorial/fireqos-new-user/)**, it is **really simple for everyone +to use QoS in Linux**. Just install the package `firehol`. It should already be available for your +distribution. If not, check the **[FireHOL Installation Guide](https://firehol.org/installing/)**. +After that, you will have the `fireqos` command. + +This is the file `/etc/firehol/fireqos.conf` we use at the netdata demo site: + +```sh + # configure the netdata ports + server_netdata_ports="tcp/19999" + + interface eth0 world bidirectional ethernet balanced rate 50Mbit + class arp + match arp + + class icmp + match icmp + + class dns commit 1Mbit + server dns + client dns + + class ntp + server ntp + client ntp + + class ssh commit 2Mbit + server ssh + client ssh + + class rsync commit 2Mbit max 10Mbit + server rsync + client rsync + + class web_server commit 40Mbit + server http + server netdata + + class client + client surfing + + class nms commit 1Mbit + match input src 10.2.3.5 +``` + +Nothing more is needed. You just run `fireqos start` to apply this configuration, restart netdata +and you have real-time visualization of the bandwidth consumption of your applications. FireQOS is +not a daemon. It will just convert the configuration to `tc` commands. It will run them and it will +exit. + +**IMPORTANT**: If you copy this configuration to apply it to your system, please adapt the +speeds - experiment in non-production environments to learn the tool, before applying it on +your servers. + +And this is what you are going to get: + +![image](https://cloud.githubusercontent.com/assets/2662304/14436322/c91d90a4-0024-11e6-9fb1-57cdef1580df.png) + +--- + +## More examples: + +This is QoS from a linux router.

-### XML instead of JSON, from bind - -The collector can also accept bind URLs that return XML output. This might required if you cannot have bind 9.10+ with JSON but you have an version of bind that supports XML statistics v3. Check [this](https://www.isc.org/blogs/bind-9-10-statistics-troubleshooting-and-zone-configuration/) for versions supported. - -In such cases, use a URL like this: - -```sh -curl "http://localhost:8888/xml/v3/server" -``` - -Only `xml` and `v3` has been tested. - -Keep in mind though, that XML parsing is done using javascript code, which requires a triple conversion: - -1. from XML to JSON using a javascript XML parser (**CPU intensive**), -2. which is then transformed to emulate the output of the JSON output of bind (**CPU intensive** - and yes the converted JSON from XML is different to the native JSON - even bind produces different names for various attributes), -3. which is then processed to generate the data for the charts (this will happen even if bind is producing JSON). - -In general, expect XML parsing to be 2 to 3 times more CPU intensive than JSON. - -**So, if you can use the JSON output of bind, prefer it over XML**. Keep also in mind that even bind will use more CPU when generating XML instead of JSON. - -The XML interface of bind is not autodetected. -You will have to provide the config file `/etc/netdata/node.d/named.conf`, like this: - -```js -{ - "enable_autodetect": false, - "update_every": 1, - "servers": [ - { - "name": "local", - "url": "http://localhost:8888/xml/v3/server", - "update_every": 1 - } - ] -} -``` - -Of course, you can monitor more than one bind servers.

On very busy servers (or weak servers), this can lead to gaps on the charts. + +You can set netdata scheduling policy in `netdata.conf`, like this: + +``` +[global] + process scheduling policy = idle +``` + +You can use the following: + +policy|description +:-----:|:-------- +`idle`|use CPU only when there is spare - this is lower than nice 19 - it is the default for netdata and it is so low that netdata will run in "slow motion" under extreme system load, resulting in short (1-2 seconds) gaps at the charts. +`other`<br/>or<br/>`nice`|this is the default policy for all processes under Linux. It provides dynamic priorities based on the `nice` level of each process. Check below for setting this `nice` level for netdata. +`batch`|This policy is similar to `other` in that it schedules the thread according to its dynamic priority (based on the `nice` value). The difference is that this policy will cause the scheduler to always assume that the thread is CPU-intensive. Consequently, the scheduler will apply a small scheduling penalty with respect to wake-up behavior, so that this thread is mildly disfavored in scheduling decisions. +`fifo`|`fifo` can be used only with static priorities higher than 0, which means that when a `fifo` threads becomes runnable, it will always immediately preempt any currently running `other`, `batch`, or `idle` thread. `fifo` is a simple scheduling algorithm without time slicing. +`rr`|a simple enhancement of `fifo`. Everything described above for `fifo` also applies to `rr`, except that each thread is allowed to run only for a maximum time quantum. +`keep`<br/>or<br/>`none`|do not set scheduling policy, priority or nice level - i.e. keep running with whatever it is set already (e.g. by systemd). + +For more information see `man sched`. + +### scheduling priority for `rr` and `fifo` + +Once the policy is set to one of `rr` or `fifo`, the following will appear: + +``` +[global] + process scheduling priority = 0 +``` + +These priorities are usually from 0 to 99. Higher numbers make the process more important. + +### nice level for policies `other` or `batch` + +When the policy is set to `other`, `nice`, or `batch`, the following will appear: + +``` +[global] + process nice level = 19 +``` + +## scheduling settings and systemd + +netdata will not be able to set its scheduling policy and priority to more important values when it is started as the `netdata` user (systemd case). + +You can set these settings at `/etc/systemd/system/netdata.service`: + +``` +[Service] +# By default netdata switches to scheduling policy idle, which makes it use CPU, only +# when there is spare available. +# Valid policies: other (the system default) | batch | idle | fifo | rr +#CPUSchedulingPolicy=other + +# This sets the maximum scheduling priority netdata can set (for policies: rr and fifo). +# netdata (via [global].process scheduling priority in netdata.conf) can only lower this value. +# Priority gets values 1 (lowest) to 99 (highest). +#CPUSchedulingPriority=1 + +# For scheduling policy 'other' and 'batch', this sets the lowest niceness of netdata. +# netdata (via [global].process nice level in netdata.conf) can only increase the value set here. +#Nice=0 +``` + +Run `systemctl daemon-reload` to reload these changes. + +Now, tell netdata to keep these settings, as set by systemd, by editing `netdata.conf` and setting: + +``` +[global] + process scheduling policy = keep +``` + +Using the above, whatever scheduling settings you have set at `netdata.service` will be maintained by netdata. + + +#### Example 1: netdata with nice -1 on non-systemd systems + +On a system that is not based on systemd, to make netdata run with nice level -1 (a little bit higher to the default for all programs), edit netdata.conf and set: + +``` +[global] + process scheduling policy = other + process nice level = -1 +``` + +then execute this to restart netdata: + +```sh +sudo service netdata restart +``` + + +#### Example 2: netdata with nice -1 on systemd systems + +On a system that is based on systemd, to make netdata run with nice level -1 (a little bit higher to the default for all programs), edit netdata.conf and set: + +``` +[global] + process scheduling policy = keep +``` + +edit /etc/systemd/system/netdata.service and set: + +``` +[Service] +CPUSchedulingPolicy=other +Nice=-1 +``` + +then execute: + +```sh +sudo systemctl daemon-reload +sudo systemctl restart netdata +``` + +## virtual memory + +You may notice that netdata's virtual memory size, as reported by `ps` or `/proc/pid/status` +(or even netdata's applications virtual memory chart) is unrealistically high. + +For example, it may be reported to be 150+MB, even if the resident memory size is just 25MB. +Similar values may be reported for netdata plugins too. + +Check this for example: A netdata installation with default settings on Ubuntu 16.04LTS. +The top chart is **real memory used**, while the bottom one is **virtual memory**: + +![image](https://cloud.githubusercontent.com/assets/2662304/19013772/5eb7173e-87e3-11e6-8f2b-a2ccfeb06faf.png) + +#### why this happens? + +The system memory allocator allocates virtual memory arenas, per thread running. +On Linux systems this defaults to 16MB per thread on 64 bit machines. So, if you get the +difference between real and virtual memory and divide it by 16MB you will roughly get the +number of threads running. + +The system does this for speed. Having a separate memory arena for each thread, allows the +threads to run in parallel in multi-core systems, without any locks between them. + +This behaviour is system specific. For example, the chart above when running netdata on alpine +linux (that uses **musl** instead of **glibc**) is this: + +![image](https://cloud.githubusercontent.com/assets/2662304/19013807/7cf5878e-87e4-11e6-9651-082e68701eab.png) + +#### can we do anything to lower it? + +Since netdata already uses minimal memory allocations while it runs (i.e. it adapts its memory +on start, so that while repeatedly collects data it does not do memory allocations), it already +instructs the system memory allocator to minimize the memory arenas for each thread. We have also +added [2 configuration options](https://github.com/netdata/netdata/blob/5645b1ee35248d94e6931b64a8688f7f0d865ec6/src/main.c#L410-L418) +to allow you tweak these settings. + +However, even if we instructed the memory allocator to use just one arena, it seems it allocates +an arena per thread. + +netdata also supports `jemalloc` and `tcmalloc`, however both behave exactly the same to the +glibc memory allocator in this aspect. + +#### Is this a problem? + +No, it is not. + +Linux reserves real memory (physical RAM) in pages (on x86 machines pages are 4KB each). +So even if the system memory allocator is allocating huge amounts of virtual memory, +only the 4KB pages that are actually used are reserving physical RAM. The **real memory** chart +on netdata application section, shows the amount of physical memory these pages occupy(it +accounts the whole pages, even if parts of them are actually used). + + +## Debugging + +When you compile netdata with debugging: + +1. compiler optimizations for your CPU are disabled (netdata will run somewhat slower) + +2. a lot of code is added all over netdata, to log debug messages to `/var/log/netdata/debug.log`. However, nothing is printed by default. netdata allows you to select which sections of netdata you want to trace. Tracing is activated via the config option `debug flags`. It accepts a hex number, to enable or disable specific sections. You can find the options supported at [log.h](https://github.com/netdata/netdata/blob/master/libnetdata/log/log.h). They are the `D_*` defines. The value `0xffffffffffffffff` will enable all possible debug flags. + +Once netdata is compiled with debugging and tracing is enabled for a few sections, the file `/var/log/netdata/debug.log` will contain the messages. + +> Do not forget to disable tracing (`debug flags = 0`) when you are done tracing. The file `debug.log` can grow too fast. + +#### compiling netdata with debugging + +To compile netdata with debugging, use this: + +```sh +# step into the netdata source directory +cd /usr/src/netdata.git + +# run the installer with debugging enabled +CFLAGS="-O1 -ggdb -DNETDATA_INTERNAL_CHECKS=1" ./netdata-installer.sh +``` + +The above will compile and install netdata with debugging info embedded. You can now use `debug flags` to set the section(s) you need to trace. + +#### debugging crashes + +We have made the most to make netdata crash free. If however, netdata crashes on your system, it would be very helpful to provide stack traces of the crash. Without them, is will be almost impossible to find the issue (the code base is quite large to find such an issue by just objerving it). + +To provide stack traces, **you need to have netdata compiled with debugging**. There is no need to enable any tracing (`debug flags`). + +Then you need to be in one of the following 2 cases: + +1. netdata crashes and you have a core dump + +2. you can reproduce the crash + +If you are not on these cases, you need to find a way to be (i.e. if your system does not produce core dumps, check your distro documentation to enable them). + +#### netdata crashes and you have a core dump + +> you need to have netdata compiled with debugging info for this to work (check above) + +Run the following command and post the output on a github issue. + +```sh +gdb $(which netdata) /path/to/core/dump +``` + +#### you can reproduce a netdata crash on your system + +> you need to have netdata compiled with debugging info for this to work (check above) + +Install the package `valgrind` and run: + +```sh +valgrind $(which netdata) -D +``` + +netdata will start and it will be a lot slower. Now reproduce the crash and `valgrind` will dump on your console the stack trace. Open a new github issue and post the output. + diff --git a/daemon/common.c b/daemon/common.c new file mode 100644 index 000000000..e278cdf7c --- /dev/null +++ b/daemon/common.c @@ -0,0 +1,16 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "common.h" + +char *netdata_configured_hostname = NULL;

It will not store any other data for each value in the time series database. +Since all its values are stored in a time series with fixed step, the time each value +corresponds can be calculated at run time, using the position of a value in the round robin database. + +The default history is 3.600 entries, thus it will need 14.4KB for each chart dimension. +If you need 1.000 dimensions, they will occupy just 14.4MB. + +Of course, 3.600 entries is a very short history, especially if data collection frequency is set +to 1 second. You will have just one hour of data. + +For a day of data and 1.000 dimensions, you will need: 86.400 seconds * 4 bytes * 1.000 +dimensions = 345MB of RAM. + +Currently the only option you have to lower this number is to use +**[Memory Deduplication - Kernel Same Page Merging - KSM](#ksm)**. + +## Memory modes + +Currently netdata supports 5 memory modes: + +1. `ram`, data are purely in memory. Data are never saved on disk. This mode uses `mmap()` and + supports [KSM](#ksm). + +2. `save`, (the default) data are only in RAM while netdata runs and are saved to / loaded from + disk on netdata restart. It also uses `mmap()` and supports [KSM](#ksm). + +3. `map`, data are in memory mapped files. This works like the swap. Keep in mind though, this + will have a constant write on your disk. When netdata writes data on its memory, the Linux kernel + marks the related memory pages as dirty and automatically starts updating them on disk. + Unfortunately we cannot control how frequently this works. The Linux kernel uses exactly the + same algorithm it uses for its swap memory. Check below for additional information on running a + dedicated central netdata server. This mode uses `mmap()` but does not support [KSM](#ksm). + +4. `none`, without a database (collected metrics can only be streamed to another netdata). + +5. `alloc`, like `ram` but it uses `calloc()` and does not support [KSM](#ksm). This mode is the + fallback for all others except `none`. + +You can select the memory mode by editing netdata.conf and setting: + +``` +[global] + # ram, save (the default, save on exit, load on start), map (swap like) + memory mode = save + + # the directory where data are saved + cache directory = /var/cache/netdata +``` + +## Running netdata in embedded devices + +Embedded devices usually have very limited RAM resources available. + +There are 2 settings for you to tweak: + +1. `update every`, which controls the data collection frequency +2. `history`, which controls the size of the database in RAM + +By default `update every = 1` and `history = 3600`. This gives you an hour of data with per +second updates. + +If you set `update every = 2` and `history = 1800`, you will still have an hour of data, but +collected once every 2 seconds. This will **cut in half** both CPU and RAM resources consumed +by netdata. Of course experiment a bit. On very weak devices you might have to use +`update every = 5` and `history = 720` (still 1 hour of data, but 1/5 of the CPU and RAM resources). + +You can also disable [data collection plugins](../collectors) you don't need. +Disabling such plugins will also free both CPU and RAM resources. + +## running a dedicated central netdata server + +netdata allows streaming data between netdata nodes. This allows us to have a central netdata +server that will maintain the entire database for all nodes, and will also run health checks/alarms +for all nodes. + +For this central netdata, memory size can be a problem. Fortunately, netdata supports several +memory modes. What is interesting for this setup is `memory mode = map`. + +In this mode, the database of netdata is stored in memory mapped files. netdata continues to read +and write the database in memory, but the kernel automatically loads and saves memory pages from/to +disk. + +**We suggest _not_ to use this mode on nodes that run other applications.** There will always be +dirty memory to be synced and this syncing process may influence the way other applications work. +This mode however is ideal when we need a central netdata server that would normally need huge +amounts of memory. Using memory mode `map` we can overcome all memory restrictions. + +There are a few kernel options that provide finer control on the way this syncing works. But before +explaining them, a brief introduction of how netdata database works is needed. + +For each chart, netdata maps the following files: + +1. `chart/main.db`, this is the file that maintains chart information. Every time data are collected + for a chart, this is updated. + +2. `chart/dimension_name.db`, this is the file for each dimension. At its beginning there is a + header, followed by the round robin database where metrics are stored. + +So, every time netdata collects data, the following pages will become dirty: + +1. the chart file +2. the header part of all dimension files +3. if the collected metrics are stored far enough in the dimension file, another page will + become dirty, for each dimension + +Each page in Linux is 4KB. So, with 200 charts and 1000 dimensions, there will be 1200 to 2200 4KB +pages dirty pages every second. Of course 1200 of them will always be dirty (the chart header and +the dimensions headers) and 1000 will be dirty for about 1000 seconds (4 bytes per metric, 4KB per +page, so 1000 seconds, or 16 minutes per page). + +Hopefully, the Linux kernel does not sync all these data every second. The frequency they are +synced is controlled by `/proc/sys/vm/dirty_expire_centisecs` or the +`sysctl` `vm.dirty_expire_centisecs`. The default on most systems is 3000 (30 seconds). + +On a busy server centralizing metrics from 20+ servers you will experience this: + +![image](https://cloud.githubusercontent.com/assets/2662304/23834750/429ab0dc-0764-11e7-821a-d7908bc881ac.png) + +As you can see, there is quite some stress (this is `iowait`) every 30 seconds. + +A simple solution is to increase this time to 10 minutes (60000). This is the same system +with this setting in 10 minutes: + +![image](https://cloud.githubusercontent.com/assets/2662304/23834784/d2304f72-0764-11e7-8389-fb830ffd973a.png) + +Of course, setting this to 10 minutes means that data on disk might be up to 10 minutes old if you +get an abnormal shutdown. + +There are 2 more options to tweak: + +1. `dirty_background_ratio`, by default `10`. +2. `dirty_ratio`, by default `20`. + +These control the amount of memory that should be dirty for disk syncing to be triggered. +On dedicated netdata servers, you can use: `80` and `90` respectively, so that all RAM is given +to netdata. + +With these settings, you can expect a little `iowait` spike once every 10 minutes and in case +of system crash, data on disk will be up to 10 minutes old. + +![image](https://cloud.githubusercontent.com/assets/2662304/23835030/ba4bf506-0768-11e7-9bc6-3b23e080c69f.png) + +To have these settings automatically applied on boot, create the file `/etc/sysctl.d/netdata-memory.conf` with these contents: + +``` +vm.dirty_expire_centisecs = 60000 +vm.dirty_background_ratio = 80 +vm.dirty_ratio = 90 +vm.dirty_writeback_centisecs = 0 +``` + +## KSM + +Netdata offers all its round robin database to kernel for deduplication. + +In the past KSM has been criticized for consuming a lot of CPU resources. +Although this is true when KSM is used for deduplicating certain applications, it is not true with +netdata, since the netdata memory is written very infrequently (if you have 24 hours of metrics in +netdata, each byte at the in-memory database will be updated just once per day). + +KSM is a solution that will provide 60+% memory savings to netdata. + +#### Enable KSM in kernel + +You need to run a kernel compiled with: + +```sh +CONFIG_KSM=y +``` + +When KSM is enabled at the kernel is just available for the user to enable it. + +So, if you build a kernel with `CONFIG_KSM=y` you will just get a few files in `/sys/kernel/mm/ksm`. Nothing else happens. There is no performance penalty (apart I guess from the memory this code occupies into the kernel). + +The files that `CONFIG_KSM=y` offers include: + +- `/sys/kernel/mm/ksm/run` by default `0`. You have to set this to `1` for the kernel to spawn `ksmd`. +- `/sys/kernel/mm/ksm/sleep_millisecs`, by default `20`. The frequency ksmd should evaluate memory for deduplication. +- `/sys/kernel/mm/ksm/pages_to_scan`, by default `100`. The amount of pages ksmd will evaluate on each run. + +So, by default `ksmd` is just disabled. It will not harm performance and the user/admin can control the CPU resources he/she is willing `ksmd` to use. + +#### Run `ksmd` kernel daemon + +To activate / run `ksmd` you need to run: + +```sh +echo 1 >/sys/kernel/mm/ksm/run +echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs +``` + +With these settings ksmd does not even appear in the running process list (it will run once per second and evaluate 100 pages for de-duplication). + +Put the above lines in your boot sequence (`/etc/rc.local` or equivalent) to have `ksmd` run at boot. + +## Monitoring Kernel Memory de-duplication performance + +Netdata will create charts for kernel memory de-duplication performance, like this: + +![image](https://cloud.githubusercontent.com/assets/2662304/11998786/eb23ae54-aab6-11e5-94d4-e848e8a5c56a.png) diff --git a/database/rrd.c b/database/rrd.c new file mode 100644 index 000000000..119efa62e --- /dev/null +++ b/database/rrd.c @@ -0,0 +1,150 @@ +// SPDX-License-Identifier: GPL-3.0-or-later +#define NETDATA_RRD_INTERNALS 1 + +#include "rrd.h" + +// ---------------------------------------------------------------------------- +// globals + +/* +// if not zero it gives the time (in seconds) to remove un-updated dimensions +// DO NOT ENABLE +// if dimensions are removed, the chart generation will have to run again +int rrd_delete_unupdated_dimensions = 0;

+Each netdata node runs an independent thread evaluating health monitoring checks. +This thread has lock free access to the database, so that it can operate as a watchdog. + +Health checks (alarms) are attached to netdata charts, allowing netdata to automatically +activate an alarm as soon as a chart is created. This is very important for +netdata, since many charts are dynamically created during runtime (for example, the +chart tracking network interface packet drops, is automatically created on the first +packet dropped). + +Netdata also supports alarm **templates**, so that an alarm can be attached to all +the charts of the same context (i.e. all network interfaces, or all disks, or all mysql servers, etc.) + +Each alarm can execute a single query to the database using statistical algorithms against past data, +but alarms can be combined. So, if you need 2 queries in the database, you can combine +2 alarms together (both will run a query to the database, and the results can be combined). + +Each alarm has unlimited access to all the metrics collected. So, a single alarm can +use expressions combining the latest value of any number of metrics. + +## Health configuration reference + +Stock netdata health configuration is in `/usr/lib/netdata/conf.d/health.d`. +These files can be overwritten by copying them and editing them in `/etc/netdata/health.d` +(run `/etc/netdata/edit-config` to edit them). + +In `/etc/netdata/health.d` you can also put any number of files (in any number of sub-directories) +with a suffix `.conf` to have them processed by netdata. + +Health configuration can be reloaded at any time, without restarting netdata. +Just send netdata the SIGUSR2 signal, like this: + +```sh +killall -USR2 netdata +``` + +### Entities in the health files + +There are 2 entities: + +1. **alarms**, which are attached to specific charts, and + +2. **templates**, which define rules that should be applied to all charts having a + specific `context`. You can use this feature to apply **alarms** to all disks, + all network interfaces, all mysql databases, all nginx web servers, etc. + +Both of these entities have exactly the same format and feature set. +The only difference is the label `alarm` or `template`. + +netdata supports overriding **templates** with **alarms**. +For example, when a template is defined for a set of charts, an alarm with exactly the +same name attached to the same chart the template matches, will have higher precedence +(i.e. netdata will use the alarm on this chart and prevent the template from being applied +to it). + +### The format + +The following lines are parsed. + +#### alarm line `alarm` or `template` + +This line starts an alarm or alarm template. + +``` +alarm: NAME +``` + +or + +``` +template: NAME +``` + +This line has to be first on each alarm or template. +`NAME` is anything you would like to name it (the only symbols allowed are `.` and `_`). + +--- + +#### alarm line `on` + +This line defines the data the alarm should be attached to. + +For alarms: + +``` +on: CHART +``` + +For `CHART` you can use a chart `id` or `name` of the chart, as shown on the dashboard. + +For alarm templates: + +``` +on: CONTEXT +``` + +`CONTEXT` is the template of a chart. For example the charts `mysql_local.net` and +`mysql_server2.net` have the same context: `mysql.net`. So, you can use this to apply +alarms to all `mysql.net` charts. + +To find the `CONTEXT` of a chart hover over its date, above the legend. A tooltip will +appear with this format `plugin:nodule, context`. For example, the bandwidth chart of +a network interface says: + +``` +proc:/proc/dev/dev, net.net +``` + +So, `plugin = proc`, `module = /proc/net/dev` and `context = net.net`. + +--- + +#### alarm line `os` + +This alarm or template will be used only if the O/S of the host loading it, matches this +pattern list. The value is a space separated list of simple patterns (use `*` as wildcard, +prefix with `!` for a negative match, order is important). + +``` +os: linux freebsd macos +``` + +--- + +#### alarm line `hosts` + +This alarm or template will be used only if the hostname of the host loading it, matches +this pattern list. The value is a space separated list of simple patterns (use `*` as wildcard, +prefix with `!` for a negative match, order is important). + +``` +hosts: server1 server2 database* !redis3 redis* +``` + +The above says: use this alarm on all hosts named `server1`, `server2`, `database*`, and +all `redis*` except `redis3`. + +This is useful when you centralize metrics from multiple hosts, to one netdata. + +--- + +#### alarm line `families` + +This line is only used in alarm templates. It filters the charts. So, if you need to create +an alarm template for a few of a kind of chart (a few of your disks, or a few of your network +interfaces, or a few your mysql servers, etc), you can create an alarm template that would +normally be applied to all of them, and filter them by family. + +The format is: + +``` +families: SIMPLE PATTERN LIST +``` + +Simple patterns list is a lists of space separated patterns. Use ` * ` as wildcard and ` ! ` +for a negative match. Processing is left to right, and on the first hit (positive or negative), +processing stops. + +So. `families: *` means, match anything, while `families: !bad*pattern* *` means anything +except `bad*pattern*` (where `*` is a wildcard to match any sequence of characters). + +The family of a chart is usually the submenu of the netdata dashboard it appears. + +--- + +#### alarm line `lookup` + +This lines makes a database lookup to find a value. This result of this lookup is available as `$this`. + +The format is: + +``` +lookup: METHOD AFTER [at BEFORE] [every DURATION] [OPTIONS] [of DIMENSIONS] +``` + +Everything is the same with [badges](../web/api/badges/). In short: + +- `METHOD` is one of `average`, `min`, `max`, `sum`, `incremental-sum`. + This is required. + +- `AFTER` is a relative number of seconds, but it also accepts a single letter for changing + the units, like `-1s` = 1 second in the past, `-1m` = 1 minute in the past, `-1h` = 1 hour + in the past, `-1d` = 1 day in the past. You need a negative number (i.e. how far in the past + to look for the value). **This is required**. + +- `at BEFORE` is by default 0 and is not required. Using this you can define the end of the + lookup. So data will be evaluated between `AFTER` and `BEFORE`. + +- `every DURATION` sets the updated frequency of the lookup (supports single letter units as + above too). + +- `OPTIONS` is a space separated list of `percentage`, `absolute`, `min2max`, `unaligned`, + `match-ids`, `match-names`. Check the badges documentation for more info. + +- `of DIMENSIONS` is optional and has to be the last parameter. Dimensions have to be separated + by `,` or `|`. The space characters found in dimensions will be kept as-is (a few dimensions + have spaces in their names). This accepts netdata simple patterns and the `match-ids` and + `match-names` options affect the searches for dimensions. + +The result of the lookup will be available as `$this` and `$NAME` in expressions. +The timestamps of the timeframe evaluated by the database lookup is available as variables +`$after` and `$before` (both are unix timestamps). + +--- + +#### alarm line `calc` + +This expression is evaluated just after the `lookup` (if any). Its purpose is to apply some +calculation before using the value looked up from the db. + +You can also have an expression without a lookup, using other variables that are available. + +The result of the calculation will be available as `$this` in warning and critical expressions +(overwriting the `lookup` one). + +Format: + +``` +calc: EXPRESSION +``` + +Check [Expressions](#expressions) for more information. + +--- + +#### alarm line `every` + +Sets the update frequency of this alarm. This is the same to the `every DURATION` given +in the `lookup` lines. + +Format: + +``` +every: DURATION +``` + +`DURATION` accepts `s` for seconds, `m` is minutes, `h` for hours, `d` for days. + +--- + +#### alarm lines `green` and `red` + +Set the green and red thresholds of a chart. Both are available as `$green` and `$red` in +expressions. If multiple alarms define different thresholds, the ones defined by the first +alarm will be used. These will eventually visualized on the dashboard, so only one set of +them is allowed. If you need multiple sets of them in different alarms, use absolute numbers +instead of `$red` and `$green`. + +Format: + +``` +green: NUMBER +red: NUMBER +``` + +--- + +#### alarm lines `warn` and `crit` + +These expressions should evaluate to true or false (alternatively non-zero or zero). +They trigger the alarm. Both are optional. + +Format: + +``` +warn: EXPRESSION +crit: EXPRESSION +``` +Check [Expressions](#expressions) for more information. + +--- + +#### alarm line `to` + +This will be the first parameter of the script to be executed when the alarm switches status. +Its meaning is left up to the `exec` script. + +The default `exec` script, `alarm-notify.sh`, uses this field as a space separated list of roles, +which are then consulted to find the exact recipients per notification method. + +Format: + +``` +to: ROLE1 ROLE2 ROLE3 ... +``` + +--- + +#### alarm line `exec` + +The script that will be executed when the alarm changes status. + +Format: + +``` +exec: SCRIPT +``` + +The default `SCRIPT` is netdata's `alarm-notify.sh`, which supports all the notifications +methods netdata supports, including custom hooks. + +--- + +#### alarm line `delay` + +This is used to provide optional hysteresis settings for the notifications, to defend +against notification floods. These settings do not affect the actual alarm - only the time +the `exec` script is executed. + +Format: + +``` +delay: [[[up U] [down D] multiplier M] max X] +``` + +- `up U` defines the delay to be applied to a notification for an alarm that raised its status + (i.e. CLEAR to WARNING, CLEAR to CRITICAL, WARNING to CRITICAL). For example, `up 10s`, the + notification for this event will be sent 10 seconds after the actual event. This is used in + hope the alarm will get back to its previous state within the duration given. The default `U` + is zero. + +- `down D` defines the delay to be applied to a notification for an alarm that moves to lower + state (i.e. CRITICAL to WARNING, CRITICAL to CLEAR, WARNING to CLEAR). For example, `down 1m` + will delay the notification by 1 minute. This is used to prevent notifications for flapping + alarms. The default `D` is zero. + +- `mutliplier M` multiplies `U` and `D` when an alarm changes state, while a notification is + delayed. The default multiplier is `1.0`. + +- `max X` defines the maximum absolute notification delay an alarm may get. The default `X` + is `max(U * M, D * M)` (i.e. the max duration of `U` or `D` multiplied once with `M`). + + Example: + + `delay: up 10s down 15m multiplier 2 max 1h` + + The time is `00:00:00` and the status of the alarm is CLEAR. + + time of event|new status|delay|notification will be sent|why + -------------|----------|:---:|-------------------------|--- + 00:00:01 | WARNING | `up 10s` | 00:00:11 |first state switch + 00:00:05 | CLEAR | `down 15m x2`| 00:30:05 |the alarm changes state while a notification is delayed, so it was multiplied + 00:00:06 | WARNING | `up 10s x2 x2` | 00:00:26 |multiplied twice + 00:00:07|CLEAR|`down 15m x2 x2 x2`|00:45:07|multiplied 3 times. + + So: + - `U` and `D` are multiplied by `M` every time the alarm changes state (any state, not just + their matching one) and a delay is in place. + - All are reset to their defaults when the alarm switches state without a delay in place. + +--- + +### Expressions + +netdata has an internal [infix expression parser](../libnetdata/eval). +This parses expressions and creates an internal structure that allows fast execution of them. + +These operators are supported `+`, `-`, `*`, `/`, `<`, `<=`, `<>`, `!=`, `>`, `>=`, `&&`, `||`, +`!`, `AND`, `OR`, `NOT`. Boolean operators result in either `1` (true) or `0` (false). + +The conditional evaluation operator `?` is supported too. Using this operator IF-THEN-ELSE +conditional statements can be specified. The format is: `(condition) ? (true expression) : +(false expression)`. So, netdata will first evaluate the `condition` and based on the result +will either evaluate `true expression` or `false expression`. +Example: `($this > 0) ? ($avail * 2) : ($used / 2)`. +Nested such expressions are also supported (i.e. `true expression` and `false expression` can +contain conditional evaluations). + +Expressions also support the `abs()` function. + +Expressions can have variables. Variables start with `$`. Check below for more information. + +There are two special values you can use: + + - `nan`, for example `$this != nan` will check if the variable `this` is available. + A variable can be `nan` if the database lookup failed. All calculations (i.e. addition, + multiplication, etc) with a `nan` result in a `nan`. + + - `inf`, for example `$this != inf` will check if `this` is not infinite. A value or + variable can be infinite if divided by zero. All calculations (i.e. addition, + multiplication, etc) with a `inf` result in a `inf`. + +--- + +### Special use of the conditional operator + +A common (but not necessarily obvious) use of the conditional evaluation operator is +to provide [hysteresis](https://en.wikipedia.org/wiki/Hysteresis) around the critical +or warning thresholds. This usage helps to avoid bogus messages resulting from small +variations in the value when it is varying regularly but staying close to the threshold +value, without needing to delay sending messages at all. + +An example of such usage from the default CPU usage alarms bundled with netdata is: + +``` +warn: $this > (($status >= $WARNING) ? (75) : (85)) +crit: $this > (($status == $CRITICAL) ? (85) : (95)) +``` + +The above say: +* If the alarm is currently a warning, then the threshold for being considered a warning + is 75, otherwise it's 85. + +* If the alarm is currently critical, then the threshold for being considered critical + is 85, otherwise it's 95. + +Which in turn, results in the following behavior: +* While the value is rising, it will trigger a warning when it exceeds 85, and a critical + alert when it exceeds 95. + +* While the value is falling, it will return to a warning state when it goes below 85, + and a normal state when it goes below 75. + +* If the value is constantly varying between 80 and 90, then it will trigger a warning the + first time it goes above 85, but will remain a warning until it goes below 75 (or goes above 85). + +* If the value is constantly varying between 90 and 100, then it will trigger a critical alert + the first time it goes above 95, but will remain a critical alert goes below 85 (at which + point it will return to being a warning). + +--- + +### Variables + +netdata supports 3 new internal indexes for variables that will be used in health monitoring: + + - **chart local variables**. All the dimensions of the chart are exposed as local variables. + All chart alarms names are exposed as variables too. + + Charts also define a few special variables: + + - `$last_collected_t` is the unix timestamp of the last data collection + - `$collected_total_raw` is the sum of all the dimensions (their last collected values) + - `$update_every` is the update frequency of the chart + - `$green` and `$red` the threshold defined in alarms (these are per chart - the charts + inherits them from the the first alarm that defined them) + + Chart dimensions define their last calculated (i.e. interpolated) value, exactly as + shown on the charts, but also a variable with their name and suffix `_raw` that resolves + to the last collected value - as collected and another with suffix `_last_collected_t` + that resolves to unix timestamp the dimension was last collected (there may be dimensions + that fail to be collected while others continue normally). + + - **family variables**. Families are used to group charts together. For example all `eth0` + charts, have `family = eth0`. This index includes all local variables, but if there are + overlapping variables, only the first are exposed. + + - **host variables**. All the dimensions of all charts, including all alarms, in fullname. + Fullname is `CHART.VARIABLE`, where `CHART` is either the chart id or the chart name (both + are supported). + + - **special variables*** are: + + - `this`, which is resolved to the value of the current alarm. + + - `status`, which is resolved to the current status of the alarm (the current = the last + status, i.e. before the current database lookup and the evaluation of the `calc` line). + This values can be compared with `$REMOVED`, `$UNINITIALIZED`, `$UNDEFINED`, `$CLEAR`, + `$WARNING`, `$CRITICAL`. These values are incremental, ie. `$status > $CLEAL` works as + expected. + + - `now`, which is resolved to current unix timestamp. + +You can find all the variables that can be used for a given chart, using +`http://your.netdata.ip:19999/api/v1/alarm_variables?chart=NAME`. +This will dump all the indexes from the chart's perspective. +Example: [variables for the `system.cpu` chart of the registry](https://registry.my-netdata.io/api/v1/alarm_variables?chart=system.cpu). + +## Alarm Statuses + +Alarms can have the following statuses: + + - `REMOVED` - the alarm has been deleted (this happens when a SIGUSR2 is sent to netdata + to reload health configuration) + + - `UNINITIALIZED` - the alarm is not initialized yet + + - `UNDEFINED` - the alarm failed to be calculated (i.e. the database lookup failed, + a division by zero occurred, etc) + + - `CLEAR` - the alarm is not armed / raised (i.e. is OK) + + - `WARNING` - the warning expression resulted in true or non-zero + + - `CRITICAL` - the critical expression resulted in true or non-zero + +The external script will be called for all status changes. + +## Examples + + +Check the **[health.d directory](health.d)** for all alarms shipped with netdata. + +Here are a few examples: + +### Example 1 + +A simple check if an apache server is alive: + +``` +template: apache_last_collected_secs + on: apache.requests + calc: $now - $last_collected_t + every: 10s + warn: $this > ( 5 * $update_every) + crit: $this > (10 * $update_every) +``` + +The above checks that netdata is able to collect data from apache. In detail: + +``` +template: apache_last_collected_secs +``` + +The above defines a **template** named `apache_last_collected_secs`. +The name is important since `$apache_last_collected_secs` resolves to the `calc` line. +So, try to give something descriptive. + +``` + on: apache.requests +``` + +The above applies the **template** to all charts that have `context = apache.requests` +(i.e. all your apache servers). + +``` + calc: $now - $last_collected_t +``` + +- `$now` is a standard variable that resolves to the current timestamp. + +- `$last_collected_t` is the last data collection timestamp of the chart. + So this calculation gives the number of seconds passed since the last data collection. + +``` + every: 10s +``` + +The alarm will be evaluated every 10 seconds. + +``` + warn: $this > ( 5 * $update_every) + crit: $this > (10 * $update_every) +``` + +If these result in non-zero or true, they trigger the alarm. + +- `$this` refers to the value of this alarm (i.e. the result of the `calc` line. + We could also use `$apache_last_collected_secs`. + +`$update_every` is the update frequency of the chart, in seconds. + +So, the warning condition checks if we have not collected data from apache for 5 +iterations and the critical condition checks for 10 iterations. + +### Example 2 + +Check if any of the disks is critically low on disk space: + +``` +template: disk_full_percent + on: disk.space + calc: $used * 100 / ($avail + $used) + every: 1m + warn: $this > 80 + crit: $this > 95 +``` + +`$used` and `$avail` are the `used` and `avail` chart dimensions as shown on the dashboard. + +So, the `calc` line finds the percentage of used space. `$this` resolves to this percentage. + +### Example 3 + +Predict if any disk will run out of space in the near future. + +We do this in 2 steps: + +Calculate the disk fill rate: + +``` + template: disk_fill_rate + on: disk.space + lookup: max -1s at -30m unaligned of avail + calc: ($this - $avail) / (30 * 60) + every: 15s +``` + +In the `calc` line: `$this` is the result of the `lookup` line (i.e. the free space 30 minutes +ago) and `$avail` is the current disk free space. So the `calc` line will either have a positive +number of GB/second if the disk if filling up, or a negative number of GB/second if the disk is +freeing up space. + +There is no `warn` or `crit` lines here. So, this template will just do the calculation and +nothing more. + +Predict the hours after which the disk will run out of space: + +``` + template: disk_full_after_hours + on: disk.space + calc: $avail / $disk_fill_rate / 3600 + every: 10s + warn: $this > 0 and $this < 48 + crit: $this > 0 and $this < 24 +``` + +The `calc` line estimates the time in hours, we will run out of disk space. Of course, only +positive values are interesting for this check, so the warning and critical conditions check +for positive values and that we have enough free space for 48 and 24 hours respectively. + +Once this alarm triggers we will receive an email like this: + +![image](https://cloud.githubusercontent.com/assets/2662304/17839993/87872b32-6802-11e6-8e08-b2e4afef93bb.png) + +### Example 4 + +Check if any network interface is dropping packets: + +``` +template: 30min_packet_drops + on: net.drops + lookup: sum -30m unaligned absolute + every: 10s + crit: $this > 0 +``` + +The `lookup` line will calculate the sum of the all dropped packets in the last 30 minutes. + +The `crit` line will issue a critical alarm if even a single packet has been dropped. + +Note that the drops chart does not exist if a network interface has never dropped a single packet. +When netdata detects a dropped packet, it will add the chart and it will automatically attach this +alarm to it. + +## Troubleshooting + +You can compile netdata with [debugging](../daemon#debugging) and then set in `netdata.conf`: + +``` +[global] + debug flags = 0x0000000000800000 +``` + +Then check your `/var/log/netdata/debug.log`. It will show you how it works. +Important: this will generate a lot of output in debug.log. + +You can find the context of charts by looking up the chart in either +`http://your.netdata:19999/netdata.conf` or `http://your.netdata:19999/api/v1/charts`. + +You can find how netdata interpreted the expressions by examining the alarm at +`http://your.netdata:19999/api/v1/alarms?all`. For each expression, netdata will return the +expression as given in its config file, and the same expression with additional parentheses +added to indicate the evaluation flow of the expression. + diff --git a/health/health.c b/health/health.c new file mode 100644 index 000000000..ae0c464b1 --- /dev/null +++ b/health/health.c @@ -0,0 +1,750 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "health.h" + +unsigned int default_health_enabled = 1;

Amazon SNS works kind of similarly to Netdata's own notification system, allowing dispatch of a single notification to multiple subscribers of different types. Among other things, SNS supports sending notifications to: + +* Email addresses. +* Mobile Phones via SMS. +* HTTP or HTTPS web hooks. +* AWS Lambda functions. +* AWS SQS queues. +* Mobile applications via push notifications. + +To get this working, you will need: + +* The Amazon Web Services CLI tools. Most distributions provide these with the package name `awscli`. +* An actual home directory for the user you run Netdata as, instead of just using `/` as a home directory. Setup of this is distribution specific. `/var/lib/netdata` is the recommended directory (because the permissions will already be correct) if you are using a dedicated user (which is how most distributions work). +* An Amazon SNS topic to send notifications to with one or more subscribers. The [Getting Started](https://docs.aws.amazon.com/sns/latest/dg/GettingStarted.html) section of the Amazon SNS documentation covers the basics of how to set this up. Make note of the Topic ARN when you create the topic. +* While not mandatory, it is highly recommended to create a dedicated IAM user on your account for netdata to send notifications. This user needs to have programmatic access, and should only allow access to SNS. If you're really paranoid, you can create one for each system or group of systems. + +Once you have all the above, run the follwing command as the user netdata runs under: + + aws configure + +THis will prompt you for the access key and secret key for accessing Amazon SNS (as well as the default region and output format, but you can leave those blank because we don't use them). + +Once that's done, you're ready to go and can specify the desired topic ARN as a recipient. + +Notes: + + * Netdata's native email notification support is far better in almost all respects than it's support through Amazon SNS. If you want email notifications, use the native support, not SNS. + * If you need to change the notification format for SNS notifications, you can do so by specifying the format in `AWSSNS_MESSAGE_FORMAT` in the configuration. This variable supports all the same vairiables you can use in custom notifications. + * While Amazon SNS supports sending differently formatted messages for different delivery methods, netdata does not currently support this functionality. \ No newline at end of file diff --git a/health/notifications/discord/Makefile.inc b/health/notifications/discord/Makefile.inc new file mode 100644 index 000000000..03d0339ab --- /dev/null +++ b/health/notifications/discord/Makefile.inc @@ -0,0 +1,12 @@ +# SPDX-License-Identifier: GPL-3.0-or-later + +# THIS IS NOT A COMPLETE Makefile +# IT IS INCLUDED BY ITS PARENT'S Makefile.am +# IT IS REQUIRED TO REFERENCE ALL FILES RELATIVE TO THE PARENT + +# install these files +dist_noinst_DATA += \ + discord/README.md \ + discord/Makefile.inc \ + $(NULL) + diff --git a/health/notifications/discord/README.md b/health/notifications/discord/README.md new file mode 100644 index 000000000..5889ea099 --- /dev/null +++ b/health/notifications/discord/README.md @@ -0,0 +1,44 @@ +# Discordapp.com notifications + +This is what you will get: + +![image](https://cloud.githubusercontent.com/assets/7321975/22215935/b49ede7e-e162-11e6-98d0-ae8541e6b92e.png) + +You need: + +1.

All major syslog daemons have the ability to filter +# messages based on both log level and facility, and can often also make +# routing decisions for messages based on both factors. +# +# On Linux, the eight log levels in decreasing order of severity are: +# emerg, alert, crit, err, warning, notice, info, debug +# +# By default, warnings will be logged at the warning level, critical +# alerts at the crit level, and clear notifications at the invo level. +# +# And the 19 facilities you can log to are: +# auth, authpriv, cron, daemon, ftp, lpr, mail, news, syslog, user, +# uucp, local0, local1, local2, local3, local4, local5, local6, and local7 +# +# By default, netdata alerts will be logged to the local6 facility. +# +# Depending on your distribution, this means that either all your +# netdata alerts will by default end up in the main system log (usually +# /var/log/messages), or they won't be logged to a file at all. +# Neither of these are likely to be what you actually want, but any +# configuration to change that needs to happen in the syslog daemon +# configuration, not here. + +# This controls which facility is used by defalt for logging.

Our intention was to give +configuration options for everything imaginable. But then, documenting all +these options would require a tremendous amount of time, users would have +to search through endless pages for the option they need, etc. + +We concluded then that **configuring software like that is a waste of time +and effort**. Of course there must be plenty of configuration options, but +the implementation itself should require a lot less effort for both the +developers and the users. + +So, we did this: + +1. No configuration is required to run netdata +2. There are plenty of options to tweak +3. There is minimal documentation (or no at all) + +## Why this works? + +The configuration file is a `name = value` dictionary with `[sections]`. +Write whatever you like there as long as it follows this simple format. + +Netdata loads this dictionary and then when the code needs a value from +it, it just looks up the `name` in the dictionary at the proper `section`. +In all places, in the code, there are both the `names` and their +`default values`, so if something is not found in the configuration +file, the default is used. The lookup is made using B-Trees and hashes +(no string comparisons), so they are super fast. Also the `names` of the +settings can be `my super duper setting that once set to yes, will turn the world upside down = no` +- so goodbye to most of the documentation involved. + +Next, netdata can generate a valid configuration for the user to edit. +No need to remember anything or copy and paste settings. Just get the +configuration from the server (`/netdata.conf` on your netdata server), +edit it and save it. + +Last, what about options you believe you have set, but you misspelled? +When you get the configuration file from the server, there will be a +comment above all `name = value` pairs the server does not use. +So you know that whatever you wrote there, is not used. diff --git a/libnetdata/config/appconfig.c b/libnetdata/config/appconfig.c new file mode 100644 index 000000000..411538446 --- /dev/null +++ b/libnetdata/config/appconfig.c @@ -0,0 +1,587 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "../libnetdata.h" + +#define CONFIG_FILE_LINE_MAX ((CONFIG_MAX_NAME + CONFIG_MAX_VALUE + 1024) * 2) + +// ---------------------------------------------------------------------------- +// definitions + +#define CONFIG_VALUE_LOADED 0x01 // has been loaded from the config +#define CONFIG_VALUE_USED 0x02 // has been accessed from the program +#define CONFIG_VALUE_CHANGED 0x04 // has been changed from the loaded value or the internal default value +#define CONFIG_VALUE_CHECKED 0x08 // has been checked if the value is different from the default + +struct config_option { + avl avl;

Before netdata, this was the standard practice. However it has a few issues: + +1. due to the resources required, the number of metrics collected is limited. +2. for the same reason, the data collection frequency is not that high, at best it will be once every 10 or 15 seconds, at worst every 5 or 10 mins. +2. the central monitoring solution needs dedicated resources, thus becoming "another bottleneck" in the whole ecosystem. It also requires maintenance, administration, etc. +3. most centralized monitoring solutions are usually only good for presenting *statistics of past performance* (i.e. cannot be used for real-time performance troubleshooting). + +Netdata has a different approach: + +1. data collection happens per second +2. thousands of metrics per server are collected +3. data do not leave the server where they are collected +4. netdata servers do not talk to each other +5. your browser connects all the netdata servers + +Using netdata, your monitoring infrastructure is embedded on each server, limiting significantly the need of additional resources. netdata is blazingly fast, very resource efficient and utilizes server resources that already exist and are spare (on each server). This allows **scaling out** the monitoring infrastructure. + +However, the netdata approach introduces a few new issues that need to be addressed, one being **the list of netdata we have installed**, i.e. the URLs our netdata servers are listening. + +To solve this, netdata utilizes a **central registry**. This registry, together with certain browser features, allow netdata to provide unified cross server dashboards. For example, when you jump from server to server using the `my-netdata` menu, several session settings (like the currently viewed charts, the current zoom and pan operations on the charts, etc) are propagated to the new server, so that the new dashboard will come with exactly the same view. + +## What is the registry? + +The registry keeps track of 3 entities: + +1. **machines**: i.e. the netdata installations (a random GUID generated by each netdata the first time it starts; we call this **machine_guid**) + + For each netdata installation (each `machine_guid`) the registry keeps track of the different URLs it is accessed. + +2. **persons**: i.e. the web browsers accessing the netdata installations (a random GUID generated by the registry the first time it sees a new web browser; we call this **person_guid**) + + For each person, the registry keeps track of the netdata installations it has accessed and their URLs. + +3. **URLs** of netdata installations (as seen by the web browsers) + + For each URL, the registry keeps the URL and nothing more. Each URL is linked to *persons* and *machines*. The only way to find a URL is to know its **machine_guid** or have a **person_guid** it is linked to it. + +## Who talks to the registry? + +Your web browser **only**! Check here if this is against your policies: [how to not send any information to a thirdparty server](https://github.com/netdata/netdata/wiki/netdata-security#registry-or-how-to-not-send-any-information-to-a-thirdparty-server) + +Your netdata servers do not talk to the registry. This is a UML diagram of its operation: + +![registry](https://cloud.githubusercontent.com/assets/2662304/19448565/11a70632-94ab-11e6-9d80-f410b4acb797.png) + +## What data the registry maintains? + +Its database contains: + +- **random person GUIDs** (generated by the registry as a browser cookie) +- **random machine GUIDs** (generated by each netdata server on its first run), including the hostname of the server netdata is running (without the domain) +- **URLs** (the base URL for accessing a netdata server, as seen by the web browser) + +For *persons* and *machines*, the registry keeps links to *URLs*, each link with 2 timestamps (first time seen, last time seen) and a counter (number of times it has been seen). + +## Which is the default registry? + +`https://registry.my-netdata.io`, which is currently served by `https://london.my-netdata.io`. This registry listens to both HTTP and HTTPS requests but the default is HTTPS. + +#### Can this registry handle the global load of netdata installations? + +Yeap! The registry can handle 50.000 - 100.000 requests **per second per core** (depending on the type of CPU, the computer's memory bandwidth, etc). 50.000 is on J1900 (celeron 2Ghz). + +We believe, it can do it... + +## Every netdata can be a registry + +Yes, you read correct, **every netdata can be a registry**. Just pick one and configure it. + +**To turn any netdata into a registry**, edit `/etc/netdata/netdata.conf` and set: + +``` +[registry] + enabled = yes + registry to announce = http://your.registry:19999 +``` + +Restart your netdata to activate it. + +Then, you need to tell **all your other netdata servers to advertise your registry**, instead of the default. To do this, on each of your netdata servers, edit `/etc/netdata/netdata.conf` and set: + +``` +[registry] + enabled = no + registry to announce = http://your.registry:19999 +``` + +Note that we have not enabled the registry on the other servers. Only one netdata (the registry) needs `[registry].enabled = yes`. + +This is it. You have your registry now. + +You may also want to give your server different names under the **my-netdata** menu (i.e. to have them sorted / grouped). You can change its registry name, by setting on each netdata server: + +``` +[registry] + registry hostname = Group1 - Master DB +``` + +So this server will appear in **my-netdata** as `Group1 - Master DB`. The max name length is 50 characters. + +#### limiting access to the registry + +netdata v1.9+ support limiting access to the registry from given IPs, like this: +``` +[registry] + allow from = * +``` + +`allow from` settings are [netdata simple patterns](https://github.com/netdata/netdata/wiki/Configuration#netdata-simple-patterns): string matches that use `*` as wildcard (any number of times) and a `!` prefix for a negative match. So: `allow from = !10.1.2.3 10.*` will allow all IPs in `10.*` except `10.1.2.3`. The order is important: left to right, the first positive or negative match is used. + +Keep in mind that connections to netdata API ports are filtered by `[web].allow connections from`.

This server has to have `[registry].enabled = yes`. So, accessing the registry URL directly with your web browser, should present the dashboard of the netdata operating the registry. + +To use the registry, your web browser needs to support **third party cookies**, since the cookies are set by the registry while you are browsing the dashboard of another netdata server. The registry, the first time it sees a new web browser it tries to figure if the web browser has cookies enabled or not. It does this by setting a cookie and redirecting the browser back to itself hoping that it will receive the cookie. If it does not receive the cookie, the registry will keep redirecting your web browser back to itself, which after a few redirects will fail with an error like this: + +``` +ERROR 409: Cannot ACCESS netdata registry: https://registry.my-netdata.io responded with: {"status":"redirect","registry":"https://registry.my-netdata.io"} +``` + +This error is printed on your web browser console (press F12 on your browser to show it). diff --git a/registry/registry.c b/registry/registry.c new file mode 100644 index 000000000..4f97eb58f --- /dev/null +++ b/registry/registry.c @@ -0,0 +1,415 @@ +// SPDX-License-Identifier: GPL-3.0-or-later + +#include "../daemon/common.h" +#include "registry_internals.h" + +#define REGISTRY_STATUS_OK "ok" +#define REGISTRY_STATUS_FAILED "failed" +#define REGISTRY_STATUS_DISABLED "disabled" + +// ---------------------------------------------------------------------------- +// REGISTRY concurrency locking + +static inline void registry_lock(void) { + netdata_mutex_lock(®istry.lock);

This file holds streaming configuration for both the +sending and the receiving netdata. + +API keys are used to authorize the communication of a pair of sending-receiving netdata. +Once the communication is authorized, the sending netdata can push metrics for any number of hosts. + +You can generate an API key with the command `uuidgen`. API keys are just random GUIDs. +You can use the same API key on all your netdata, or use a different API key for any pair of +sending-receiving netdata. + +##### options for the sending node + +This is the section for the sending netdata. On the receiving node, `[stream].enabled` can be `no`. +If it is `yes`, the receiving node will also stream the metrics to another node (i.e. it will be +a `proxy`). + +``` +[stream] + enabled = yes | no + destination = IP:PORT ... + api key = XXXXXXXXXXX +``` + +This is an overview of how these options can be combined: + +target | memory<br/>mode | web<br/>mode | stream<br/>enabled | backend | alarms | dashboard +-------|:-----------:|:---:|:------:|:-------:|:---------:|:----: +headless collector|`none`|`none`|`yes`|only for `data source = as collected`|not possible|no +headless proxy|`none`|not `none`|`yes`|only for `data source = as collected`|not possible|no +proxy with db|not `none`|not `none`|`yes`|possible|possible|yes +central netdata|not `none`|not `none`|`no`|possible|possible|yes + +##### options for the receiving node + +`stream.conf` looks like this: + +```sh +# replace API_KEY with your uuidgen generated GUID +[API_KEY] + enabled = yes + default history = 3600 + default memory mode = save + health enabled by default = auto + allow from = * +``` + +You can add many such sections, one for each API key. The above are used as default values for +all hosts pushed with this API key. + +You can also add sections like this: + +```sh +# replace MACHINE_GUID with the slave /var/lib/netdata/registry/netdata.public.unique.id +[MACHINE_GUID] + enabled = yes + history = 3600 + memory mode = save + health enabled = yes + allow from = * +``` + +The above is the receiver configuration of a single host, at the receiver end. `MACHINE_GUID` is +the unique id the netdata generating the metrics (i.e. the netdata that originally collects +them `/var/lib/netdata/registry/netdata.unique.id`). So, metrics for netdata `A` that pass through +any number of other netdata, will have the same `MACHINE_GUID`. + +####### allow from + +`allow from` settings are [netdata simple patterns](../libnetdata/simple_pattern): string matches +that use `*` as wildcard (any number of times) and a `!` prefix for a negative match. +So: `allow from = !10.1.2.3 10.*` will allow all IPs in `10.*` except `10.1.2.3`. The order is +important: left to right, the first positive or negative match is used. + +`allow from` is available in netdata v1.9+ + +#### tracing + +When a `slave` is trying to push metrics to a `master` or `proxy`, it logs entries like these: + +``` +2017-02-25 01:57:44: netdata: ERROR: Failed to connect to '10.11.12.1', port '19999' (errno 111, Connection refused) +2017-02-25 01:57:44: netdata: ERROR: STREAM costa-pc [send to 10.11.12.1:19999]: failed to connect +2017-02-25 01:58:04: netdata: INFO : STREAM costa-pc [send to 10.11.12.1:19999]: initializing communication... +2017-02-25 01:58:04: netdata: INFO : STREAM costa-pc [send to 10.11.12.1:19999]: waiting response from remote netdata... +2017-02-25 01:58:14: netdata: INFO : STREAM costa-pc [send to 10.11.12.1:19999]: established communication - sending metrics... +2017-02-25 01:58:14: netdata: ERROR: STREAM costa-pc [send]: discarding 1900 bytes of metrics already in the buffer. +2017-02-25 01:58:14: netdata: INFO : STREAM costa-pc [send]: ready - sending metrics... +``` + +The receiving end (`proxy` or `master`) logs entries like these: + +``` +2017-02-25 01:58:04: netdata: INFO : STREAM [receive from [10.11.12.11]:33554]: new client connection. +2017-02-25 01:58:04: netdata: INFO : STREAM costa-pc [10.11.12.11]:33554: receive thread created (task id 7698) +2017-02-25 01:58:14: netdata: INFO : Host 'costa-pc' with guid '12345678-b5a6-11e6-8a50-00508db7e9c9' initialized, os: linux, update every: 1, memory mode: ram, history entries: 3600, streaming: disabled, health: enabled, cache_dir: '/var/cache/netdata/12345678-b5a6-11e6-8a50-00508db7e9c9', varlib_dir: '/var/lib/netdata/12345678-b5a6-11e6-8a50-00508db7e9c9', health_log: '/var/lib/netdata/12345678-b5a6-11e6-8a50-00508db7e9c9/health/health-log.db', alarms default handler: '/usr/libexec/netdata/plugins.d/alarm-notify.sh', alarms default recipient: 'root' +2017-02-25 01:58:14: netdata: INFO : STREAM costa-pc [receive from [10.11.12.11]:33554]: initializing communication... +2017-02-25 01:58:14: netdata: INFO : STREAM costa-pc [receive from [10.11.12.11]:33554]: receiving metrics... +``` + +For netdata v1.9+, streaming can also be monitored via `access.log`. + + +#### Viewing remote host dashboards, using mirrored databases + +On any receiving netdata, that maintains remote databases and has its web server enabled, +`my-netdata` menu will include a list of the mirrored databases. + +![image](https://cloud.githubusercontent.com/assets/2662304/24080824/24cd2d3c-0caf-11e7-909d-a8dd1dbb95d7.png) + +Selecting any of these, the server will offer a dashboard using the mirrored metrics. + + +## Monitoring ephemeral nodes + +Auto-scaling is probably the most trendy service deployment strategy these days. + +Auto-scaling detects the need for additional resources and boots VMs on demand, based on a template.

Pay only for what you need for the time you need it! + +In auto-scaling, all servers are ephemeral, they live for just a few hours. Every VM is a brand new instance of the application, that was automatically created based on a template. + +So, how can we monitor them? How can we be sure that everything is working as expected on all of them? + +### The netdata way + +We recently made a significant improvement at the core of netdata to support monitoring such setups. + +Following the netdata way of monitoring, we wanted: + +1. **real-time performance monitoring**, collecting **_thousands of metrics per server per second_**, visualized in interactive, automatically created dashboards. +2. **real-time alarms**, for all nodes. +3. **zero configuration**, all ephemeral servers should have exactly the same configuration, and nothing should be configured at any system for each of the ephemeral nodes. We shouldn't care if 10 or 100 servers are spawned to handle the load. +4. **self-cleanup**, so that nothing needs to be done for cleaning up the monitoring infrastructure from the hundreds of nodes that may have been monitored through time. + +#### How it works + +All monitoring solutions, including netdata, work like this: + +1. `collect metrics`, from the system and the running applications +2. `store metrics`, in a time-series database +3. `examine metrics` periodically, for triggering alarms and sending alarm notifications +4. `visualize metrics`, so that users can see what exactly is happening + +netdata used to be self-contained, so that all these functions were handled entirely by each server. The changes we made, allow each netdata to be configured independently for each function. So, each netdata can now act as: + +- a `self contained system`, much like it used to be. +- a `data collector`, that collects metrics from a host and pushes them to another netdata (with or without a local database and alarms). +- a `proxy`, that receives metrics from other hosts and pushes them immediately to other netdata servers. netdata proxies can also be `store and forward proxies` meaning that they are able to maintain a local database for all metrics passing through them (with or without alarms). +- a `time-series database` node, where data are kept, alarms are run and queries are served to visualise the metrics. + +### Configuring an auto-scaling setup + +<p align="center"> +<img src="https://cloud.githubusercontent.com/assets/2662304/23627468/96daf7ba-02b9-11e7-95ac-1f767dd8dab8.png"/> +</p> + +You need a netdata `master`. This node should not be ephemeral. It will be the node where all ephemeral nodes (let's call them `slaves`) will be sending their metrics. + +The master will need to authorize the slaves for accepting their metrics. This is done with an API key. + +#### API keys + +API keys are just random GUIDs. Use the Linux command `uuidgen` to generate one. You can use the same API key for all your `slaves`, or you can configure one API for each of them. This is entirely your decision. + +We suggest to use the same API key for each ephemeral node template you have, so that all replicas of the same ephemeral node will have exactly the same configuration. + +I will use this API_KEY: `11111111-2222-3333-4444-555555555555`. Replace it with your own. + +#### Configuring the `master` + +On the master, edit `/etc/netdata/stream.conf` (to edit it on your system run `/etc/netdata/edit-config stream.conf`) and set these: + +```bash +[11111111-2222-3333-4444-555555555555] + # enable/disable this API key + enabled = yes + + # one hour of data for each of the slaves + default history = 3600 + + # do not save slave metrics on disk + default memory = ram + + # alarms checks, only while the slave is connected + health enabled by default = auto +``` +*`stream.conf` on master, to enable receiving metrics from slaves using the API key.* + +If you used many API keys, you can add one such section for each API key. + +When done, restart netdata on the `master` node. It is now ready to receive metrics. + +#### Configuring the `slaves` + +On each of the slaves, edit `/etc/netdata/stream.conf` (to edit it on your system run `/etc/netdata/edit-config stream.conf`) and set these: + +```bash +[stream] + # stream metrics to another netdata + enabled = yes + + # the IP and PORT of the master + destination = 10.11.12.13:19999 + + # the API key to use + api key = 11111111-2222-3333-4444-555555555555 +``` +*`stream.conf` on slaves, to enable pushing metrics to master at `10.11.12.13:19999`.* + +Using just the above configuration, the `slaves` will be pushing their metrics to the `master` netdata, but they will still maintain a local database of the metrics and run health checks. To disable them, edit `/etc/netdata/netdata.conf` and set: + +```bash +[global] + # disable the local database + memory mode = none + +[health] + # disable health checks + enabled = no +``` +*`netdata.conf` configuration on slaves, to disable the local database and health checks.* + +Keep in mind that setting `memory mode = none` will also force `[health].enabled = no` (health checks require access to a local database). But you can keep the database and disable health checks if you need to. You are however sending all the metrics to the master server, which can handle the health checking (`[health].enabled = yes`) + +#### netdata unique id + +The file `/var/lib/netdata/registry/netdata.public.unique.id` contains a random GUID that **uniquely identifies each netdata**. This file is automatically generated, by netdata, the first time it is started and remains unaltaired forever. + +> If you are building an image to be used for automated provisioning of autoscaled VMs, it important to delete that file from the image, so that each instance of your image will generate its own. + +#### Troubleshooting metrics streaming + +Both the sender and the receiver of metrics log information at `/var/log/netdata/error.log`. + + +On both master and slave do this: + +``` +tail -f /var/log/netdata/error.log | grep STREAM +``` + +If the slave manages to connect to the master you will see something like (on the master): + +``` +2017-03-09 09:38:52: netdata: INFO : STREAM [receive from [10.11.12.86]:38564]: new client connection. +2017-03-09 09:38:52: netdata: INFO : STREAM xxx [10.11.12.86]:38564: receive thread created (task id 27721) +2017-03-09 09:38:52: netdata: INFO : STREAM xxx [receive from [10.11.12.86]:38564]: client willing to stream metrics for host 'xxx' with machine_guid '1234567-1976-11e6-ae19-7cdd9077342a': update every = 1, history = 3600, memory mode = ram, health auto +2017-03-09 09:38:52: netdata: INFO : STREAM xxx [receive from [10.11.12.86]:38564]: initializing communication... +2017-03-09 09:38:52: netdata: INFO : STREAM xxx [receive from [10.11.12.86]:38564]: receiving metrics... +``` + +and something like this on the slave: + +``` +2017-03-09 09:38:28: netdata: INFO : STREAM xxx [send to box:19999]: connecting... +2017-03-09 09:38:28: netdata: INFO : STREAM xxx [send to box:19999]: initializing communication... +2017-03-09 09:38:28: netdata: INFO : STREAM xxx [send to box:19999]: waiting response from remote netdata... +2017-03-09 09:38:28: netdata: INFO : STREAM xxx [send to box:19999]: established communication - sending metrics... +``` + +### Archiving to a time-series database + +The `master` netdata node can also archive metrics, for all `slaves`, to a time-series database.

This will be `green <10%`, `yellow <20%`, `orange <50%`, `blue <100%` (1 core), `red` otherwise (you define thresholds and colors on the URL). + + <a href="https://registry.my-netdata.io/#apps_cpu"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=users.cpu&dimensions=root&value_color=grey:null%7Cgreen%3C10%7Cyellow%3C20%7Corange%3C50%7Cblue%3C100%7Cred&label=root%20user%20cpu%20now&units=%25"></img></a> <a href="https://registry.my-netdata.io/#apps_cpu"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=users.cpu&dimensions=root&after=-3600&value_color=grey:null%7Cgreen%3C10%7Cyellow%3C20%7Corange%3C50%7Cblue%3C100%7Cred&label=root%20user%20average%20cpu%20last%20hour&units=%25"></img></a> + +- **mysql queries per second** + + <a href="https://registry.my-netdata.io/#mysql_local"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=mysql_local.queries&dimensions=questions&label=mysql%20queries%20now&value_color=red&units=%5Cs"></img></a> <a href="https://registry.my-netdata.io/#mysql_local"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=mysql_local.queries&dimensions=questions&after=-3600&options=unaligned&group=sum&label=mysql%20queries%20this%20hour&value_color=green&units=null"></img></a> <a href="https://registry.my-netdata.io/#mysql_local"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=mysql_local.queries&dimensions=questions&after=-86400&options=unaligned&group=sum&label=mysql%20queries%20today&value_color=blue&units=null"></img></a> + + niche ones: **mysql SELECT statements with JOIN, which did full table scans**: + + <a href="https://registry.my-netdata.io/#mysql_local_issues"><img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=mysql_local.join_issues&dimensions=scan&after=-3600&label=full%20table%20scans%20the%20last%20hour&value_color=orange&group=sum&units=null"></img></a> + +--- + +> So, every single line on the charts of a [netdata dashboard](http://london.my-netdata.io/), can become a badge and this badge can calculate **average**, **min**, **max**, or **volume** for any time-frame! And you can also vary the badge color using conditions on the calculated value. + +--- + +## How to create badges + +The basic URL is `http://your.netdata:19999/api/v1/badge.svg?option1&option2&option3&...`. + +Here is what you can put for `options` (these are standard netdata API options): + +- `chart=CHART.NAME` + + The chart to get the values from. + + **This is the only parameter required** and with just this parameter, netdata will return the sum of the latest values of all chart dimensions. + + Example: + +```html + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu"></img> + </a> +``` + + Which produces this: + + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu"></img> + </a> + +- `alarm=NAME` + + Render the current value and status of an alarm linked to the chart. This option can be ignored if the badge to be generated is not related to an alarm. + + The current value of the alarm will be rendered. The color of the badge will indicate the status of the alarm. + + For alarm badges, **both `chart` and `alarm` parameters are required**. + +- `dimensions=DIMENSION1|DIMENSION2|...` + + The dimensions of the chart to use. If you don't set any dimension, all will be used. When multiple dimensions are used, netdata will sum their values. You can append `options=absolute` if you want this sum to convert all values to positive before adding them. + + Pipes in HTML have to escaped with `%7C`. + + Example: + +```html + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&dimensions=system%7Cnice"></img> + </a> +``` + + Which produces this: + + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&dimensions=system%7Cnice"></img> + </a> + +- `before=SECONDS` and `after=SECONDS` + + The timeframe. These can be absolute unix timestamps, or relative to now, number of seconds. By default `before=0` and `after=-1` (1 second in the past). + + To get the last minute set `after=-60`. This will give the average of the last complete minute (XX:XX:00 - XX:XX:59). + + To get the max of the last hour set `after=-3600&group=max`. This will give the maximum value of the last complete hour (XX:00:00 - XX:59:59) + + Example: + +```html + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60"></img> + </a> +``` + + Which produces the average of last complete minute (XX:XX:00 - XX:XX:59): + + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60"></img> + </a> + + While this is the previous minute (one minute before the last one, again aligned XX:XX:00 - XX:XX:59): + +```html + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&before=-60&after=-60"></img> + </a> +``` + + It produces this: + + <a href="#"> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&before=-60&after=-60"></img> + </a> + +- `group=min` or `group=max` or `group=average` (the default) or `group=sum` or `group=incremental-sum` + + If netdata will have to reduce (aggregate) the data to calculate the value, which aggregation method to use. + + - `max` will find the max value for the timeframe. This works on both positive and negative dimensions. It will find the most extreme value. + + - `min` will find the min value for the timeframe. This works on both positive and negative dimensions. It will find the number closest to zero. + + - `average` will calculate the average value for the timeframe. + + - `sum` will sum all the values for the timeframe. This is nice for finding the volume of dimensions for a timeframe. So if you have a dimension that reports `X per second`, you can find the volume of the dimension in a timeframe, by adding its values in that timeframe. + + - `incremental-sum` will sum the difference of each value to its next. Let's assume you have a dimension that does not measure the rate of something, but the absolute value of it. So it has values like this "1, 5, 3, 7, 4". `incremental-sum` will calculate the difference of adjacent values. In this example, they will be `(5 - 1) + (3 - 5) + (7 - 3) + (4 - 7) = 3` (which is equal to the last value minus the first = 4 - 1). + +- `options=opt1|opt2|opt3|...` + + These fine tune various options of the API. Here is what you can use for badges (the API has more option, but only these are useful for badges): + + - `percentage`, instead of returning the value, calculate the percentage of the sum of the selected dimensions, versus the sum of all the dimensions of the chart. This also sets the units to `%`. + + - `absolute` or `abs`, turn all values positive and then sum them. + + - `display_absolute` or `display-absolute`, to use the signed value during color calculation, but display the absolute value on the badge. + + - `min2max`, when multiple dimensions are given, do not sum them, but take their `max - min`. + + - `unaligned`, when data are reduced / aggregated (e.g. the request is about the average of the last minute, or hour), netdata by default aligns them so that the charts will have a constant shape (so average per minute returns always XX:XX:00 - XX:XX:59). Setting the `unaligned` option, netdata will aggregate data without any alignment, so if the request is for 60 seconds, it will aggregate the latest 60 seconds of collected data. + +These are options dedicated to badges: + +- `label=TEXT` + + The label of the badge. + +- `units=TEXT` + + The units of the badge. If you want to put a `/`, please put a `\`. This is because netdata allows badges parameters to be given as path in URL, instead of query string. You can also use `null` or `empty` to show it without any units. + + The units `seconds`, `minutes` and `hours` trigger special formatting. The value has to be in this unit, and netdata will automatically change it to show a more pretty duration. + +- `multiply=NUMBER` + + Multiply the value with this number. The default is `1`. + +- `divide=NUMBER` + + Divide the value with this number. The default is `1`. + +- `label_color=COLOR` + + The color of the label (the left part). You can use any HTML color, include `#NNN` and `#NNNNNN`. The following colors are defined in netdata (and you can use them by name): `green`, `brightgreen`, `yellow`, `yellowgreen`, `orange`, `red`, `blue`, `grey`, `gray`, `lightgrey`, `lightgray`. These are taken from https://github.com/badges/shields so they are compatible with standard badges. + +- `value_color=COLOR:null|COLOR<VALUE|COLOR>VALUE|COLOR>=VALUE|COLOR<=VALUE|...` + + You can add a pipe delimited list of conditions to pick the color. The first matching (left to right) will be used. + + Example: `value_color=grey:null|green<10|yellow<100|orange<1000|blue<10000|red` + + The above will set `grey` if no value exists (not collected within the `gap when lost iterations above` in netdata.conf for the chart), `green` if the value is less than 10, `yellow` if the value is less than 100, etc up to `red` which will be used if no other conditions match. + + The supported operators are `<`, `>`, `<=`, `>=`, `=` (or `:`) and `!=` (or `<>`). + +- `precision=NUMBER` + + The number of decimal digits of the value. By default netdata will add: + + - no decimal digits for values > 1000 + - 1 decimal digit for values > 100 + - 2 decimal digits for values > 1 + - 3 decimal digits for values > 0.1 + - 4 decimal digits for values <= 0.1 + + Using the `precision=NUMBER` you can set your preference per badge. + +- `scale=XXX` + + This option scales the svg image. It accepts values above or equal to 100 (100% is the default scale). For example, lets get a few different sizes: + + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60&scale=100"></img> original<br/> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60&scale=125"></img> `scale=125`<br/> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60&scale=150"></img> `scale=150`<br/> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60&scale=175"></img> `scale=175`<br/> + <img src="http://registry.my-netdata.io/api/v1/badge.svg?chart=system.cpu&after=-60&scale=200"></img> `scale=200` + + +- `refresh=auto` or `refresh=SECONDS` + + This option enables auto-refreshing of images. netdata will send the HTTP header `Refresh: SECONDS` to the web browser, thus requesting automatic refresh of the images at regular intervals. + + `auto` will calculate the proper `SECONDS` to avoid unnecessary refreshes. If `SECONDS` is zero, this feature is disabled (it is also disabled by default). + + Auto-refreshing like this, works only if you access the badge directly. So, you may have to put it an `embed` or `iframe` for it to be auto-refreshed. Use something like this: + +```html +<embed src="BADGE_URL" type="image/svg+xml" height="20" /> +``` + + Another way is to use javascript to auto-refresh them. You can auto-refresh all the netdata badges on a page using javascript. You have to add a class to all the netdata badges, like this `<img class="netdata-badge" src="..."/>`. Then add this javascript code to your page (it requires jquery): + +```html +<script> + var NETDATA_BADGES_AUTOREFRESH_SECONDS = 5; + function refreshNetdataBadges() { + var now = new Date().getTime().toString(); + $('.netdata-badge').each(function() { + this.src = this.src.replace(/\&_=\d*/, '') + '&_=' + now; + }); + setTimeout(refreshNetdataBadges, NETDATA_BADGES_AUTOREFRESH_SECONDS * 1000); + } + setTimeout(refreshNetdataBadges, NETDATA_BADGES_AUTOREFRESH_SECONDS * 1000); +</script> +``` + +A more advanced badges refresh method is to include `http://your.netdata.ip:19999/refresh-badges.js` in your page. For more information and use example, [check this](https://github.com/netdata/netdata/blob/master/web/gui/refresh-badges.js). + +--- + +## Escaping URLs + +Keep in mind that if you add badge URLs to your HTML pages you have to escape the special characters: + +character|name|escape sequence +:-------:|:--:|:-------------: +` `|space (in labels and units)|`%20` +` # `|hash (for colors)|`%23` +` % `|percent (in units)|`%25` +` < `|less than|`%3C` +` > `|greater than|`%3E` +` \ `|backslash (when you need a `/`)|`%5C` +` \| `|pipe (delimiting parameters)|`%7C` + +--- + +## Using the path instead of the query string + +The badges can also be generated using the URL path for passing parameters. The format is exactly the same. + +So instead of: + + `http://your.netdata:19999/api/v1/badge.svg?option1&option2&option3&...` + +you can write: + + `http://your.netdata:19999/api/v1/badge.svg/option1/option2/option3/...` + +You can also append anything else you like, like this: + + `http://your.netdata:19999/api/v1/badge.svg/option1/option2/option3/my-super-badge.svg` + +## FAQ + +#### Is it fast? +On modern hardware, netdata can generate about **2.000 badges per second per core**, before noticing any delays. It generates a badge in about half a millisecond! + +Of course these timing are for badges that use recent data. If you need badges that do calculations over long durations (a day, or more), timing will differ. netdata logs its timings at its `access.log`, so take a look there before adding a heavy badge on a busy web site. Of course, you can cache such badges or have a cron job get them from netdata and save them at your web server at regular intervals. + + +#### Embedding badges in github + +You have 2 options a) SVG images with markdown and b) SVG images with HTML (directly in .md files). + +For example, this is the cpu badge shown above: + +- Markdown example: + +```md +[![A nice name](https://registry.my-netdata.io/api/v1/badge.svg?chart=users.cpu&dimensions=root&value_color=grey:null%7Cgreen%3C10%7Cyellow%3C20%7Corange%3C50%7Cblue%3C100%7Cred&label=root%20user%20cpu%20now&units=%25)](https://registry.my-netdata.io/#apps_cpu) +``` + +- HTML example: + +```html +<a href="https://registry.my-netdata.io/#apps_cpu"> + <img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=users.cpu&dimensions=root&value_color=grey:null%7Cgreen%3C10%7Cyellow%3C20%7Corange%3C50%7Cblue%3C100%7Cred&label=root%20user%20cpu%20now&units=%25"></img> +</a> +``` + +Both produce this: + +<a href="https://registry.my-netdata.io/#apps_cpu"> + <img src="https://registry.my-netdata.io/api/v1/badge.svg?chart=users.cpu&dimensions=root&value_color=grey:null%7Cgreen%3C10%7Cyellow%3C20%7Corange%3C50%7Cblue%3C100%7Cred&label=root%20user%20cpu%20now&units=%25"></img> +</a> + +#### auto-refreshing badges in github + +Unfortunately it cannot be done. Github fetches all the images using a proxy and rewrites all the URLs to be served by the proxy. + +You can refresh them from your browser console though. Press F12 to open the web browser console (switch to the console too), paste the following and press enter.

If not given, it defaults to `average`. +`gtime`|no|A resampling period to change the units of the metrics (i.e. setting this to `60` will convert `per second` metrics to `per minute`. If not given it defaults to granularity of the database. +`options`|no|A bitmap of options that can affect the operation of the query. Only 2 options are used by the query engine: `unaligned` and `percentage`. All the other options are used by the output formatters. The default is to return aligned data. +`dimensions`|no|A simple pattern to filter the dimensions to be queried. The default is to return all the dimensions of the chart. + +## Operation + +The query engine works as follows (in this order): + +#### Time-frame + +`after` and `before` define a time-frame, accepting: + +- **absolute timestamps** (unix timestamps, i.e. seconds since epoch). + +- **relative timestamps**: + + `before` is relative to now and `after` is relative to `before`. + + Example: `before=-60&after=-60` evaluates to the time-frame from -120 up to -60 seconds in + the past, relative to the latest entry of the database of the chart. + +The engine verifies that the time-frame requested is available at the database: + +- If the requested time-frame overlaps with the database, the excess requested + will be truncated. + +- If the requested time-frame does not overlap with the database, the engine will + return an empty data set. + +At the end of this operation, `after` and `before` are absolute timestamps. + +#### Data grouping + +Database points grouping is applied when the caller requests a time-frame to be +expressed with fewer points, compared to what is available at the database. + +There are 2 uses that enable this feature: + +- The caller requests a specific number of `points` to be returned. + + For example, for a time-frame of 10 minutes, the database has 600 points (1/sec), + while the caller requested these 10 minutes to be expressed in 200 points. + + This feature is used by netdata dashboards when you zoom-out the charts. + The dashboard is requesting the number of points the user's screen has. + This saves bandwidth and speeds up the browser (fewer points to evaluate for drawing the charts). + +- The caller requests a **re-sampling** of the database, by setting `gtime` to any value + above the granularity of the chart. + + For example, the chart's units is `requests/sec` and caller wants `requests/min`. + +Using `points` and `gtime` the query engine tries to find a best fit for **database-points** +vs **result-points** (we call this ratio `group points`). It always tries to keep `group points` +an integer. Keep in mind the query engine may shift `after` if required. + +#### Time-frame Alignment + +Alignment is a very important aspect of netdata queries. Without it, the animated +charts on the dashboards would constantly change shape during incremental updates. + +To provide consistent grouping through time, the query engine (by default) aligns +`after` and `before` to be a multiple of `group points`. + +For example, if `group points` is 60 and alignment is enabled, the engine will return +each point with durations XX:XX:00 - XX:XX:59, matching whole minutes. + +To disable alignment, pass `&options=unaligned` to the query. + +#### Query Execution + +To execute the query, the engine evaluates all dimensions of the chart, one after another. + +The engine does not evaluate dimensions that do not match the [simple pattern](../../../libnetdata/simple_pattern) +given at the `dimensions` parameter, except when `options=percentage` is given (this option +requires all the dimensions to be evaluated to find the percentage of each dimension vs to chart +total). + +For each dimension, it starts evaluating values starting at `after` (not inclusive) towards +`before` (inclusive). + +For each value it calls the **grouping method** given with the `&group=` query parameter +(the default is `average`). + +## Grouping methods + +The following grouping methods are supported.

  • You can host your dashboard anywhere.
    • -
  • You can add as many charts as you like.
    • -
  • You can have charts from many different netdata servers (add 
    data-host="http://another.netdata.server:19999/"
    to each chart).
    • -
  • You can use different chart libraries on the same page: peity, sparkline, dygraph, google, morris
    • -
  • You can customize each chart to your preferences. For each chart library most of their attributes can be given in data- attributes.
    • -
  • Each chart can have each own duration - it is controlled with the data-after attribute to give that many seconds of data.
    • -
  • Depending on the width of the chart and data-after attribute, netdata will automatically refresh the chart when it needs to be updated. For example giving 600 pixels for width for -600 seconds of data, using a chart library that needs 3 pixels per point, will yeld in a chart updated once every 3 seconds.

Sparkline Charts

-Sparkline charts support 'NULL' values, so the charts can indicate that values are missing. -Sparkline charts stretch the values to show the variations between values in more detail. -They also have mouse-hover support. -
-Sparklines are fantastic. You can inline charts in text. For example this -
is my current cpu usage (last 30 seconds), - while this -
is the bandwidth my netdata server is currently transmitting (last minute) - and this -
is the requests/sec it serves (last 3 minutes). - -

Peity Charts

-Peity charts do not support 'NULL' values, so the charts cannot indicate that values are missing. -Peity charts cannot have multiple dimensions on the charts - so netdata will use 'min2max' to show -the total of all dimensions. -

Dygraph Charts

-The fastest charting engine that can chart complete charts (not just sparklines). -The charts are zoomable (drag their contents to pan, shift with mouse wheel to zoom-in or zoom-out, double click to reset it). -Netdata magic! Realtime charts on your web page! -
-Sparklines using dygraphs -
- are also possible! This -
- is an area chart, while this -
is a stacked area chart! - - -

Morris Charts

-Unfortunatelly, Morris Charts are very slow. Here we force them to lower their detail to get acceptable results. -

C3 Charts

-C3 charts are not usable in large scale. They suffer from the following issues: -
    -
  • extreme use of transitions (implemented with D3 instead of CSS, meaning they are javascript rendered) that cannot be disabled - even opacity is hardcoded in the javascript library
    • -
  • rendering is done with SVG instead of canvas, so they use DOM elements for every point, becomimg useless if more than 500 points are drawn
    • -
  • lack of a raw data format, so every time a chart is updated, data convertion in javascript is required
    • -
  • lack of stacked charts support
    • -
-So, to avoid flashing the charts, we destroy and re-create the charts on each update. Also, since they manipulate the data with javascript we were forced to lower the detail they render to get acceptable speeds. -

NetData Custom Dashboard

+ +This is a template for building custom dashboards. To build a dashboard you just do this: + +
+<!DOCTYPE html>
+<html lang="en">
+<head>
+    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
+    <meta charset="utf-8">
+    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
+    <meta name="viewport" content="width=device-width, initial-scale=1">
+    <meta name="apple-mobile-web-app-capable" content="yes">
+    <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">
+</head>
+<body>
+    <div data-netdata="system.processes"
+        data-chart-library="dygraph"
+        data-width="600"
+        data-height="200"
+        data-after="-600"
+        ></div>
+</body>
+<script type="text/javascript" src="http://netdata.server:19999/dashboard.js"></script>
+</html>
+
+ +
    +
  • You can host your dashboard anywhere.
    • +
  • You can add as many charts as you like.
    • +
  • You can have charts from many different netdata servers (add 
    data-host="http://another.netdata.server:19999/"
    to each chart).
    • +
  • You can use different chart libraries on the same page: peity, sparkline, dygraph, google, morris
    • +
  • You can customize each chart to your preferences. For each chart library most of their attributes can be given in data- attributes.
    • +
  • Each chart can have each own duration - it is controlled with the data-after attribute to give that many seconds of data.
    • +
  • Depending on the width of the chart and data-after attribute, netdata will automatically refresh the chart when it needs to be updated. For example giving 600 pixels for width for -600 seconds of data, using a chart library that needs 3 pixels per point, will yeld in a chart updated once every 3 seconds.

+

Sparkline Charts

+Sparkline charts support 'NULL' values, so the charts can indicate that values are missing. +Sparkline charts stretch the values to show the variations between values in more detail. +They also have mouse-hover support. +
+Sparklines are fantastic. You can inline charts in text. For example this +
is my current cpu usage (last 30 seconds), + while this +
is the bandwidth my netdata server is currently transmitting (last minute) + and this +
is the requests/sec it serves (last 3 minutes). + +

Peity Charts

+Peity charts do not support 'NULL' values, so the charts cannot indicate that values are missing. +Peity charts cannot have multiple dimensions on the charts - so netdata will use 'min2max' to show +the total of all dimensions. +

Dygraph Charts

+The fastest charting engine that can chart complete charts (not just sparklines). +The charts are zoomable (drag their contents to pan, shift with mouse wheel to zoom-in or zoom-out, double click to reset it). +Netdata magic! Realtime charts on your web page! +
+Sparklines using dygraphs +
+ are also possible! This +
+ is an area chart, while this +
is a stacked area chart! + + +

Morris Charts

+Unfortunatelly, Morris Charts are very slow. Here we force them to lower their detail to get acceptable results. +

C3 Charts

+C3 charts are not usable in large scale. They suffer from the following issues: +
    +
  • extreme use of transitions (implemented with D3 instead of CSS, meaning they are javascript rendered) that cannot be disabled - even opacity is hardcoded in the javascript library
    • +
  • rendering is done with SVG instead of canvas, so they use DOM elements for every point, becomimg useless if more than 500 points are drawn
    • +
  • lack of a raw data format, so every time a chart is updated, data convertion in javascript is required
    • +
  • lack of stacked charts support
    • +
+So, to avoid flashing the charts, we destroy and re-create the charts on each update. Also, since they manipulate the data with javascript we were forced to lower the detail they render to get acceptable speeds. +
