The value can be raw data or calculated values, such as the +average (the default), minimum, or maximum. These values can then be given any type of unit. For example, CPU +utilization is represented as a percentage, disk I/O as `MiB/s`, and available RAM as an absolute value in `MiB` or +`GiB`. + +Beneath every chart (or on the right-side if you configure the dashboard) is a legend of dimensions. When there are +multiple dimensions, you'll see a different entry in the legend for each dimension. + +The **Apps CPU Time** chart (with the [context](#contexts) `apps.cpu`), which visualizes CPU utilization of +different types of processes/services/applications on your node, always provides a vibrant example of a chart with +multiple dimensions. + + + +The chart shows 13 unique dimensions, such as `httpd` for the CPU utilization for web servers, `kernel` for anything +related to the Linux kernel, and so on.

While we believe Netdata's +[distributed architecture](/docs/store/distributed-data-architecture.md) is ideal for speed and scale, streaming +provides centralization options for those who want to maintain only a single TSDB instance. + +## Streaming basics + +There are three types of nodes in Netdata's streaming ecosystem. + +- **Parent**: A node, running Netdata, that receives streamed metric data. +- **Child**: A node, running Netdata, that streams metric data to one or more parent. +- **Proxy**: A node, running Netdata, that receives metric data from a child and "forwards" them on to a + separate parent node. + +Netdata uses API keys, which are just random GUIDs, to authorize the communication between child and parent nodes. We +recommend using `uuidgen` for generating API keys, which can then be used across any number of streaming connections. +Or, you can generate unique API keys for each parent-child relationship. + +Once the parent node authorizes the child's API key, the child can start streaming metrics. + +It's important to note that the streaming connection uses TCP, UDP, or Unix sockets, _not HTTP_. To proxy streaming +metrics, you need to use a proxy that tunnels [OSI layer 4-7 +traffic](https://en.wikipedia.org/wiki/OSI_model#Layer_4:_Transport_Layer) without interfering with it, such as +[SOCKS](https://en.wikipedia.org/wiki/SOCKS) or Nginx's [TCP/UDP load +balancing](https://docs.nginx.com/nginx/admin-guide/load-balancer/tcp-udp-load-balancer/). + +## Supported streaming configurations + +Netdata supports any combination of parent, child, and proxy nodes that you can imagine. Any node can act as both a +parent, child, or proxy at the same time, sending or receiving streaming metrics from any number of other nodes. + +Here are a few example streaming configurations: + +- **Headless collector**: + - Child `A`, _without_ a database or web dashboard, streams metrics to parent `B`. + - `A` metrics are only available via the local Agent dashboard for `B`. + - `B` generates alarms for `A`. +- **Replication**: + - Child `A`, _with_ a database and web dashboard, streams metrics to parent `B`. + - `A` metrics are available on both local Agent dashboards, and can be stored with the same or different metrics + retention policies. + - Both `A` and `B` generate alarms. +- **Proxy**: + - Child `A`, _with or without_ a database, sends metrics to proxy `C`, also _with or without_ a database. `C` sends + metrics to parent `B`. + - Any node with a database can generate alarms. + +## Viewing streamed metrics + +Parent nodes feature a **Replicated Nodes** section in the left-hand panel, which opens with the hamburger icon + +in the top navigation.

To encrypt streaming connections, you first need to [enable TLS +support](/web/server/README.md#enabling-tls-support) on the parent. With encryption enabled on the receiving side, you +need to instruct the child to use TLS/SSL as well. On the child's `stream.conf`, configure the destination as follows: + +``` +[stream] + destination = host:port:SSL +``` + +The word `SSL` appended to the end of the destination tells the child that connections must be encrypted. + +> While Netdata uses Transport Layer Security (TLS) 1.2 to encrypt communications rather than the obsolete SSL protocol, +> it's still common practice to refer to encrypted web connections as `SSL`. Many vendors, like Nginx and even Netdata +> itself, use `SSL` in configuration files, whereas documentation will always refer to encrypted communications as `TLS` +> or `TLS/SSL`. + +#### Certificate verification + +When TLS/SSL is enabled on the child, the default behavior will be to not connect with the parent unless the server's +certificate can be verified via the default chain. In case you want to avoid this check, add the following to the +child's `stream.conf` file: + +``` +[stream] + ssl skip certificate verification = yes +``` + +#### Trusted certificate + +If you've enabled [certificate verification](#certificate-verification), you might see errors from the OpenSSL library +when there's a problem with checking the certificate chain (`X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY`). More +importantly, OpenSSL will reject self-signed certificates. + +Given these known issues, you have two options. If you trust your certificate, you can set the options `CApath` and +`CAfile` to inform Netdata where your certificates, and the certificate trusted file, are stored. + +For more details about these options, you can read about [verify +locations](https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_load_verify_locations.html). + +Before you changed your streaming configuration, you need to copy your trusted certificate to your child system and add +the certificate to OpenSSL's list. + +On most Linux distributions, the `update-ca-certificates` command searches inside the `/usr/share/ca-certificates` +directory for certificates. You should double-check by reading the `update-ca-certificate` manual (`man +update-ca-certificate`), and then change the directory in the below commands if needed. + +If you have `sudo` configured on your child system, you can use that to run the following commands. If not, you'll have +to log in as `root` to complete them. + +``` +# mkdir /usr/share/ca-certificates/netdata +# cp parent_cert.pem /usr/share/ca-certificates/netdata/parent_cert.crt +# chown -R netdata.netdata /usr/share/ca-certificates/netdata/ +``` + +First, you create a new directory to store your certificates for Netdata. Next, you need to change the extension on your +certificate from `.pem` to `.crt` so it's compatible with `update-ca-certificate`. Finally, you need to change +permissions so the user that runs Netdata can access the directory where you copied in your certificate. + +Next, edit the file `/etc/ca-certificates.conf` and add the following line: + +``` +netdata/parent_cert.crt +``` + +Now you update the list of certificates running the following, again either as `sudo` or `root`: + +``` +# update-ca-certificates +``` + +> Some Linux distributions have different methods of updating the certificate list. For more details, please read this +> guide on [adding trusted root certificates](https://github.com/Busindre/How-to-Add-trusted-root-certificates). + +Once you update your certificate list, you can set the stream parameters for Netdata to trust the parent certificate. +Open `stream.conf` for editing and change the following lines: + +``` +[stream] + CApath = /etc/ssl/certs/ + CAfile = /etc/ssl/certs/parent_cert.pem +``` + +With this configuration, the `CApath` option tells Netdata to search for trusted certificates inside `/etc/ssl/certs`. +The `CAfile` option specifies the Netdata parent certificate is located at `/etc/ssl/certs/parent_cert.pem`. With this +configuration, you can skip using the system's entire list of certificates and use Netdata's parent certificate instead. + +#### Expected behaviors + +With the introduction of TLS/SSL, the parent-child communication behaves as shown in the table below, depending on the +following configurations: + +- **Parent TLS (Yes/No)**: Whether the `[web]` section in `netdata.conf` has `ssl key` and `ssl certificate`. +- **Parent port TLS (-/force/optional)**: Depends on whether the `[web]` section `bind to` contains a `^SSL=force` or + `^SSL=optional` directive on the port(s) used for streaming. +- **Child TLS (Yes/No)**: Whether the destination in the child's `stream.conf` has `:SSL` at the end. +- **Child TLS Verification (yes/no)**: Value of the child's `stream.conf` `ssl skip certificate verification` + parameter (default is no). + +| Parent TLS enabled | Parent port SSL | Child TLS | Child SSL Ver. | Behavior | +| :----------------- | :--------------- | :-------- | :------------- | :--------------------------------------------------------------------------------------------------------------------------------------- | +| No | - | No | no | Legacy behavior. The parent-child stream is unencrypted. | +| Yes | force | No | no | The parent rejects the child connection. | +| Yes | -/optional | No | no | The parent-child stream is unencrypted (expected situation for legacy child nodes and newer parent nodes) | +| Yes | -/force/optional | Yes | no | The parent-child stream is encrypted, provided that the parent has a valid TLS/SSL certificate. Otherwise, the child refuses to connect. | +| Yes | -/force/optional | Yes | yes | The parent-child stream is encrypted. | + +### Proxy + +A proxy is a node that receives metrics from a child, then streams them onward to a parent. To configure a proxy, +configure it as a receiving and a sending Netdata at the same time. + +Netdata proxies may or may not maintain a database for the metrics passing through them. When they maintain a database, +they can also run health checks (alarms and notifications) for the remote host that is streaming the metrics. + +In the following example, the proxy receives metrics from a child node using the `API_KEY` of +`66666666-7777-8888-9999-000000000000`, then stores metrics using `dbengine`. It then uses the `API_KEY` of +`11111111-2222-3333-4444-555555555555` to proxy those same metrics on to a parent node at `203.0.113.0`. + +```conf +[stream] + enabled = yes + destination = 203.0.113.0 + api key = 11111111-2222-3333-4444-555555555555 + +[66666666-7777-8888-9999-000000000000] + enabled = yes + default memory mode = dbengine +``` + +### Ephemeral nodes + +Netdata can help you monitor ephemeral nodes, such as containers in an auto-scaling infrastructure, by always streaming +metrics to any number of permanently-running parent nodes. + +On the parent, set the following in `stream.conf`: + +```conf +[11111111-2222-3333-4444-555555555555] + # enable/disable this API key + enabled = yes + + # one hour of data for each of the child nodes + default history = 3600 + + # do not save child metrics on disk + default memory = ram + + # alarms checks, only while the child is connected + health enabled by default = auto +``` + +On the child nodes, set the following in `stream.conf`: + +```bash +[stream] + # stream metrics to another Netdata + enabled = yes + + # the IP and PORT of the parent + destination = 10.11.12.13:19999 + + # the API key to use + api key = 11111111-2222-3333-4444-555555555555 +``` + +In addition, edit `netdata.conf` on each child node to disable the database and alarms. + +```bash +[global] + # disable the local database + memory mode = none + +[health] + # disable health checks + enabled = no +``` + +## Troubleshooting + +Both parent and child nodes log information at `/var/log/netdata/error.log`. + +If the child manages to connect to the parent you will see something like (on the parent): + +``` +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 child: + +``` +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... +``` + +The following sections describe the most common issues you might encounter when connecting parent and child nodes. + +### Slow connections between parent and child + +When you have a slow connection between parent and child, Netdata raises a few different errors. Most of the +errors will appear in the child's `error.log`. + +```bash +netdata ERROR : STREAM_SENDER[CHILD HOSTNAME] : STREAM CHILD HOSTNAME [send to PARENT IP:PARENT PORT]: too many data pending - buffer is X bytes long, +Y unsent - we have sent Z bytes in total, W on this connection. Closing connection to flush the data. +``` + +On the parent side, you may see various error messages, most commonly the following: + +``` +netdata ERROR : STREAM_PARENT[CHILD HOSTNAME,[CHILD IP]:CHILD PORT] : read failed: end of file +``` + +Another common problem in slow connections is the child sending a partial message to the parent. In this case, the +parent will write the following to its `error.log`: + +``` +ERROR : STREAM_RECEIVER[CHILD HOSTNAME,[CHILD IP]:CHILD PORT] : sent command 'B' which is not known by netdata, for host 'HOSTNAME'. Disabling it. +``` + +In this example, `B` was part of a `BEGIN` message that was cut due to connection problems. + +Slow connections can also cause problems when the parent misses a message and then receives a command related to the +missed message. For example, a parent might miss a message containing the child's charts, and then doesn't know +what to do with the `SET` message that follows. When that happens, the parent will show a message like this: + +``` +ERROR : STREAM_RECEIVER[CHILD HOSTNAME,[CHILD IP]:CHILD PORT] : requested a SET on chart 'CHART NAME' of host 'HOSTNAME', without a dimension. Disabling it. +``` + +### Child cannot connect to parent + +When the child can't connect to a parent for any reason (misconfiguration, networking, firewalls, parent +down), you will see the following in the child's `error.log`. + +``` +ERROR : STREAM_SENDER[HOSTNAME] : Failed to connect to 'PARENT IP', port 'PARENT PORT' (errno 113, No route to host) +``` + +### 'Is this a Netdata?' + +This question can appear when Netdata starts the stream and receives an unexpected response. This error can appear when +the parent is using SSL and the child tries to connect using plain text. You will also see this message when +Netdata connects to another server that isn't Netdata. The complete error message will look like this: + +``` +ERROR : STREAM_SENDER[CHILD HOSTNAME] : STREAM child HOSTNAME [send to PARENT HOSTNAME:PARENT PORT]: server is not replying properly (is it a netdata?). +``` + +### Stream charts wrong + +Chart data needs to be consistent between child and parent nodes. If there are differences between chart data on +a parent and a child, such as gaps in metrics collection, it most often means your child's `memory mode` +does not match the parent's. To learn more about the different ways Netdata can store metrics, and thus keep chart +data consistent, read our [memory mode documentation](/database/README.md). + +### Forbidding access + +You may see errors about "forbidding access" for a number of reasons. It could be because of a slow connection between +the parent and child nodes, but it could also be due to other failures. Look in your parent's `error.log` for errors +that look like this: + +``` +STREAM [receive from [child HOSTNAME]:child IP]: `MESSAGE`. Forbidding access." +``` + +`MESSAGE` will have one of the following patterns: + +- `request without KEY` : The message received is incomplete and the KEY value can be API, hostname, machine GUID. +- `API key 'VALUE' is not valid GUID`: The UUID received from child does not have the format defined in [RFC + 4122](https://tools.ietf.org/html/rfc4122) +- `machine GUID 'VALUE' is not GUID.`: This error with machine GUID is like the previous one. +- `API key 'VALUE' is not allowed`: This stream has a wrong API key. +- `API key 'VALUE' is not permitted from this IP`: The IP is not allowed to use STREAM with this parent. +- `machine GUID 'VALUE' is not allowed.`: The GUID that is trying to send stream is not allowed. +- `Machine GUID 'VALUE' is not permitted from this IP. `: The IP does not match the pattern or IP allowed to connect to + use stream. + +### Netdata could not create a stream + +The connection between parent and child is a stream. When the parent can't convert the initial connection into +a stream, it will write the following message inside `error.log`: + +``` +file descriptor given is not a valid stream +``` + +After logging this error, Netdata will close the stream. diff --git a/docs/monitor/view-active-alarms.md b/docs/monitor/view-active-alarms.md index 63ddfdde..b23e2d72 100644 --- a/docs/monitor/view-active-alarms.md +++ b/docs/monitor/view-active-alarms.md @@ -37,8 +37,10 @@ Cloud](https://user-images.githubusercontent.com/1153921/108564813-f08d2000-72c0 ## Local Netdata Agent dashboard -Find the bell 🔔 icon in the top navigation to bring up a modal that shows currently raised alarms, all running alarms, -and the alarms log.

Our Principles - -Netdata has designed this policy to be consistent with the following principles: - -Privacy policies should be human readable and easy to find. -Data collection, storage, and processing should be simplified as much as possible to enhance security, ensure consistency, and make the practices easy for users to understand. -Data practices should always meet the reasonable expectations of users. - -## 3. Personal Information ND Collects and How it is Used - -As used in this policy, “personal information” means information that would allow someone to identify you, including your name, email address, IP address, or other information from which someone could deduce your identity. - -ND collects and uses personal information in the following ways: - -Website and Analytics: When you visit our Websites and use our Services, ND collects some information about your activities through tools such as Google Analytics. The type of information that we collect focuses on general information such as country or city where you are located, pages visited, time spent on pages, heat-map of visitors’ activity on the site, information about the browser you are using, etc. ND collects and uses this information pursuant to our legitimate interest in enhancing the security and utility of our Services. The information we gather and process is used in the aggregate to spot trends without deliberately identifying individuals. - -Note that you can learn about Google’s practices in connection with its analytics services and how to opt out of it by downloading the Google Analytics opt-out browser add-on, available at <https://tools.google.com/dlpage/gaoptout>. - -Information from Cookies: We and our service providers (for example, Google Analytics as described above) may collect information using cookies or similar technologies for the purposes described above and below. Cookies are pieces of information that are stored by your browser on the hard drive or memory of your computer or other Internet access device. Cookies may enable us to personalize your experience on the Services, maintain a persistent session, passively collect demographic information about your computer, and monitor advertisements and other activities. The Websites may use different kinds of cookies and other types of local storage (such as browser-based or plugin-based local storage). - -ND Registry: The global registry, together with certain browser features, allow Netdata to provide unified cross-server dashboards, via the node menu. -The menu lists the Netdata servers you have visited. For example, when you jump from server to server using the node 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. The global registry keeps track of 4 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. - -4. **accounts**: i.e. the information used to sign-in via one of the available sign-in methods. Depending on the method, this may include an email, an email and a profile picture. - -For _persons/accounts_ 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). -_machines_, _persons_, and timestamps are stored in the Netdata registry regardless of whether you sign in or not. - -If sending this information is against your policies, you can [run your own registry](/registry/README.md#run-your-own-registry). -Note that ND versions with the 'Sign in' feature of the ND Cloud do not use the global registry. - -ND Cloud: When you sign up to obtain a user account via the 'Sign in' link on the ND agent user interface, ND is granted access to personal information in the user profile of the authentication provider you choose (e.g. GitHub or Google). ND collects and uses this personal information pursuant to its legitimate interest in establishing and maintaining your account providing you with the features we provide Registered Users. We may use your email address to contact you regarding changes to this policy or other applicable policies.

Every time the daemon is started or stopped and every time a fatal condition is encountered, Netdata collects system information and sends it to GA via an http call. The information collected for all events is: - -- Netdata version -- OS name, version, id, id_like -- Kernel name, version, architecture -- Virtualization technology -- Containerization technology - Furthermore, the FATAL event sends the Netdata process & thread info, along with the file, function and line of the fatal error. - -The statistics calculated from this information are used for: - -1. **Quality assurance**, to help us understand if Netdata behaves as expected and help us identify repeating issues for certain distributions or environment. - -2. **Usage statistics**, to help us focus on the parts of Netdata that are used the most, or help us identify the extend our development decisions influence the community. - -To opt-out from sending anonymous statistics, you can create a file called `.opt-out-from-anonymous-statistics` under the user configuration directory (usually `/etc/netdata`). - -Emails and Newsletters: When you sign up to receive updates from Netdata or otherwise subscribe to one of our mailing lists, you will be asked to provide some personal information. ND collects and uses this personal information pursuant to its legitimate interest in providing news and updates to, and collaborating with, its supporters and volunteers. - -Email Analytics: When you receive communications from ND after signing up for the ND newsletter, campaign updates, or other ongoing email communications from ND, we may use analytics to track whether you open the mail, click on the links, and otherwise interact with what we send. You may opt out of this tracking by choosing to get plain-text emails from ND. ND collects and uses this personal information pursuant to its legitimate interest in understanding the interests of its community of supporters and volunteers in order to provide more relevant news and updates. - -Other Voluntarily Provided Information: When you provide feedback to Netdata, sign a petition distributed by ND, or otherwise submit personal information to Netdata, ND collects and uses this personal information pursuant to its legitimate interest in better understanding our community of supporters and volunteers and in furtherance of the particular program or activity to which you provided feedback or other input. - -## 4. Retention of Personal Information - -The majority of the personal information collected and used as explained in Section 3 above is aggregated and stored in a central database provided by a third party service provider. ND aggregates this data pursuant to its legitimate interest in having information stored in a single location to minimize complexity, increase consistency in internal practices, better understand its community of supporters and volunteers, and enhance the security of the data. - -## 5. Access to Your Personal Information - -You are generally entitled to access personal information that Netdata holds and to have inaccurate data corrected or removed to the extent ND still maintains it. In certain circumstances, you also may have the right to object for legitimate reasons to the processing or transfer of personal information. If you wish to exercise any of these rights, please write to legal@netdata.cloud explaining your request. - -## 6. Disclosure of Your Personal Information - -ND does not disclose personal information to third parties except as specified elsewhere in this policy and in the following instances: - -We may disclose your personal information to third parties in a good faith belief that such disclosure is reasonably necessary to (a) take action regarding suspected illegal activities; (b) enforce or apply our Master Terms and this Privacy Policy; (c) enforce our Charter, including the Code of Conduct and policies contained and incorporated therein, or (d) comply with legal process, such as a search warrant, subpoena, statute, or court order. - -## 7. Security of Your Personal Information - -Netdata has implemented reasonable physical, technical, and organizational security measures for personal information that Netdata processes against accidental or unlawful destruction, or accidental loss, alteration, unauthorized disclosure or access, in compliance with applicable law. However, no website can fully eliminate security risks. If any data breach occurs, we will post a reasonably prominent notice to the Websites and comply with all other applicable data privacy requirements including, when required, personal notice to you if you have provided and we have maintained an email address for you. - -The ND Cloud Services have security risks in addition to those described above. Among other things, they are vulnerable to DNS attacks, and using any ND Cloud Service may increase the risk of phishing. - -## 8. Children - -The Services are not directed at children under the age of 13. Consistent with the U.S. federal Children’s Online Privacy Protection Act of 1998 (COPPA), we will never knowingly request personal information from anyone under the age of 13 without requiring parental consent. Our Master Terms specifically prohibit anyone using our Services from submitting any personally identifiable information about persons under 13 years of age. Any person who provides their personal information to ND through the Services represents that they are 13 years of age or older. - -## 9. Third Party Service Providers - -Netdata uses many third party service providers in connection with the Services, including website hosting services, database management, credit card processing, and many more. Some of these service providers may place session cookies on your computer, and they may collect and store your personal information on our behalf in accordance with the data practices and purposes explained above in Section 3. - -## 10. Third Party Sites - -The Services may provide links to a wide variety of third party websites. You should consult the respective privacy policies of these third-party websites. This Privacy Policy does not apply to, and we cannot control the activities of, such other websites. - -## 11.
