 ### Packaging
 
 This stage is executed only on "master" brach and allows us to create a new tag just looking at git commit message.
 It executes one script called `releaser.sh` which is responsible for creating a release on GitHub by using
 [hub](https://github.com/github/hub). This script is also executing other scripts which can also be used in other
 CI jobs:
-  - `tagger.sh`
-  - `generate_changelog.sh`
-  - `build.sh`
-  - `create_artifacts.sh`
+  - `.travis/tagger.sh`
+  - `.travis/generate_changelog.sh`
+  - `packaging/docker/build.sh`
+  - `.travis/create_artifacts.sh`
 
 Alternatively new release can be also created by pushing new tag to master branch.
+Additionally this step is also executing `.travis/labeler.sh` which is a temporary workaround to automatically label 
+issues and PR. This script should be replaced with GitHub Actions when they are available to public.

 only once a day due to github rate limiter.

[Open a github issue](https://github.com/netdata/netdata/issues) to discuss it. Feedback is very important for open-source projects.

+### Sponsor a part of Netdata
 
-NetData is all about simplicity and meaningful presentation. It's impossible for a handful of people to know which metrics really matter when monitoring a particular software or hardware component you are interested in. Be specific about what should be collected, how the information should be presented in the dashboard and which alarms make sense in most situations.
+Netdata is a complex system, with many integrations for the various  collectors, backends and notification endpoints. As a result, we rely on help from "sponsors", a concept similar to "power users" or "product owners". To become a sponsor, just let us know in any Github issue and we will record your GitHub username in a "CONTRIBUTORS.md" in the appropriate directory.
+
+#### Sponsor a collector
+
+Netdata is all about simplicity and meaningful presentation. A "sponsor" for a collector does the following:
+ - Assists the devs with feedback on the charts.
+ - Specifies the alarms that would make sense for each metric.
+ - When the implementation passes QA, tests the implementation in production.
+ - Uses the charts and alarms in his/her day to day work and provides additional feedback.
+ - Requests additional improvements as things change (e.g. new versions of an API are available).
+
+#### Sponsor a backend
+
+We already support various [backends](backends) and we intend to support more. A "sponsor" for a backend: 
+- Suggests ways in which the information in Netdata could best be exposed to the particular backend, to facilitate meaningful presentation.
+ - When the implementation passes QA, tests the implementation in production.
+- Uses the backend in his/her day to day work and provides additional feedback, after the backend is delivered.
+ - Requests additional improvements as things change (e.g. new versions of the backend API are available).
+
+#### Sponsor a notification method
+
+Netdata delivers alarms via various [notification methods](health/notifications). A "sponsor" for a notification method:
+- Points the devs to the documentation for the API and identifies any unusual features of interest (e.g. the ability in Slack to send a notification either to a channel or to a user). 
+- Uses the notification method in production and provides feedback.
+- Requests additional improvements as things change (e.g. new versions of the API are available).

+However, it's not always that simple. Our [PR approval process](#pr-approval-process) and the several merges we do every day may cause your fork to get behind the Netdata master. If you worked on something that has changed in the meantime, you will be required to do a git rebase, to bring your fork to the correct state. A very easy to follow guide on how to do it without learning all the intricacies of GitHub can be found [here](https://medium.com/@ruthmpardee/git-fork-workflow-using-rebase-587a144be470)

+One thing you will need to do only for your first pull request in Netdata is to accept the CLA. Until you do, the automated check for the CLA acceptance will be showing as failed. 
+
+### PR approval process
+
+Each PR automatically [requires a review](https://help.github.com/articles/about-required-reviews-for-pull-requests/) from the code owners specified in `.github/CODEOWNERS`. Depending on the files contained in your PR, several people may be need to approve it.
+
+We also have a series of automated checks running, such as linters to check code quality and QA tests. If you get an error or warning in any of those checks, you will need to click on the link included in the check to identify the root cause, so you can fix it.
+
+One special type of automated check is the "WIP" check. You may add "[WIP]" to the title of the PR, to tell us that the particular request is "Work In Progress" and should not be merged. You're still not done with it, you created it to get some feedback. When you're ready to get the final approvals and get it merged, just remove the "[WIP]" string from the title of your PR and the "WIP" check will pass.

+netdata (1.7.0) - 2017-07-16
+
+ * netdata is still spreading fast
+
+   we are at 320.000 users and 132.000 servers
+
+   Almost 100k new users, 52k new installations and 800k docker pulls
+   since the previous release, 4 and a half months ago.
+
+   netdata user base grows at about 1000 new users and 600 new servers
+   per day. Thank you. You are awesome.
+
+ * The next release (v1.8) will be focused on providing a global health
+   monitoring service, for all netdata users, for free.
+
+ * netdata is now a (very fast) fully featured statsd server and the
+   only one with automatic visualization: push a statsd metric and hit
+   F5 on the netdata dashboard: your metric visualized. It also supports
+   synthetic charts, defined by you, so that you can correlate and
+   visualize your application the way you like it.
+
+ * netdata got new installation options
+   It is now easier than ever to install netdata - we also distribute a
+   statically linked netdata x86_64 binary, including key dependencies
+   (like bash, curl, etc) that can run everywhere a Linux kernel runs
+   (CoreOS, CirrOS, etc).
+
+ * metrics streaming and replication has been improved significantly.
+   All known issues have been solved and key enhancements have been added.
+   Headless collectors and proxies can now send metrics to backends when
+   data source = as collected.
+
+ * backends have got quite a few enhancements, including host tags and
+   metrics filtering at the netdata side;
+   prometheus support has been re-written to utilize more prometheus
+   features and provide more flexibility and integration options.
+
+ * netdata now monitors ZFS (on Linux and FreeBSD), ElasticSearch,
+   RabbitMQ, Go applications (via expvar), ipfw (on FreeBSD 11), samba,
+   squid logs (with web_log plugin).
+
+ * netdata dashboard loading times have been improved significantly
+   (hit F5 a few times on a netdata dashboard - it is now amazingly fast),
+   to support dashboards with thousands of charts.
+
+ * netdata alarms now support custom hooks, so you can run whatever you
+   like in parallel with netdata alarms.
+
+ * As usual, this release brings dozens of more improvements, enhancements
+   and compatibility fixes.
+
+
+netdata (1.6.0) - 2017-03-20
+
+ * birthday release: 1 year netdata
+
+   netdata was first published on March 30th, 2016.
+   It has been a crazy year since then:
+
+     225.000 unique netdata users
+             currently, at 1.000 new unique users per day
+
+      80.000 unique netdata installations
+             currently, at 500 new installation per day
+
+     610.000 docker pulls on docker hub
+
+   4.000.000 netdata sessions served
+             currently, at 15.000 sessions served per day
+
+      20.000 github stars
+
+             Thank you!
+          You are awesome!
+
+ * central netdata is here
+
+   This is the first release that supports real-time streaming of
+   metrics between netdata servers.
+
+   netdata can now be:
+
+   - autonomous host monitoring
+     (like it always has been)
+
+   - headless data collector
+     (collect and stream metrics in real-time to another netdata)
+
+   - headless proxy
+     (collect metrics from multiple netdata and stream them to another netdata)
+
+   - store and forward proxy
+     (like headless proxy, but with a local database)
+
+   - central database
+     (metrics from multiple hosts are aggregated)
+
+   metrics databases can be configured on all nodes and each node maintaining
+   a database may have a different retention policy and possibly run
+   (even different) alarms on them.
+
+ * monitoring ephemeral nodes
+
+   netdata now supports monitoring autoscaled ephemeral nodes,
+   that are started and stopped on demand (their IP is not known).
+
+   When the ephemeral nodes start streaming metrics to the central
+   netdata, the central netdata will show register them at "my-netdata"
+   menu on the dashboard.
+
+   For more information check:
+   https://github.com/netdata/netdata/tree/master/streaming#monitoring-ephemeral-nodes
+
+ * monitoring ephemeral containers and VM guests
+
+   netdata now cleans up container, guest VM, network interfaces and mounted
+   disk metrics, disabling automatically their alarms too.
+
+   For more information check:
+   https://github.com/netdata/netdata/tree/master/collectors/cgroups.plugin#monitoring-ephemeral-containers
+
+ * apps.plugin ported for FreeBSD
+
+   @vlvkobal has ported "apps.plugin" to FreeBSD. netdata can now provide
+   "Applications", "Users" and "User Groups" on FreeBSD.
+
+ * web_log plugin
+
+   @l2isbad has done a wonderful job creating a unified web log parsing plugin
+   for all kinds of web server logs. With it, netdata provides real-time
+   performance information and health monitoring alarms for web applications
+   and web sites!
+
+   For more information check:
+   https://github.com/netdata/netdata/blob/master/collectors/python.d.plugin/web_log#web_log
+
+ * backends
+
+   netdata can now archive metrics to `JSON` backends
+   (both push, by @lfdominguez, and pull modes).
+
+ * IPMI monitoring
+
+   netdata now has an IPMI plugin (based on freeipmi)
+   for monitoring server hardware.
+
+   The plugin creates (up to) 8 charts:
+
+    1. number of sensors by state
+    2. number of events in SEL
+    3. Temperatures CELCIUS
+    4. Temperatures FAHRENHEIT
+    5. Voltages
+    6. Currents
+    7. Power
+    8. Fans
+
+   It also supports alarms (including the number of sensors in critical state).
+
+   For more information, check:
+   https://github.com/netdata/netdata/tree/master/collectors/freeipmi.plugin
+
+ * new plugins
+
+   @l2isbad builds python data collection plugins for netdata at an wonderfull
+   rate! He rocks!
+
+    - **web_log** for monitoring in real-time all kinds of web server log files @l2isbad

+
+ At a glance:
+
+ - the fastest netdata ever (with a better look too)!
+ - improved IoT and containers support!
+ - alarms improved in almost every way!
+
+ - new plugins:
+      softnet netdev,
+      extended TCP metrics,
+      UDPLite
+      NFS v2, v3 client (server was there already),
+      NFS v4 server & client,
+      APCUPSd,
+      RetroShare
+

+      cgroups,
+      hddtemp,
+      sensors,
+      phpfm,
+      tc (QoS)
+
+ In detail:
+
+ * improved alarms
+
+   Many new alarms have been added to detect common kernel
+   configuration errors and old alarms have been re-worked
+   to avoid notification floods.
+
+   Alarms now support notification hysteresis (both static
+   and dynamic), notification self-cancellation, dynamic
+   thresholds based on current alarm status
+
+ * improved alarm notifications
+
+   netdata now supports:
+
+   - email notifications
+   - slack.com notifications on slack channels
+   - pushover.net notifications (mobile push notifications)
+   - telegram.org notifications
+
+   For all the above methods, netdata supports role-based
+   notifications, with multiple recipients for each role
+   and severity filtering per recipient!
+
+   Also, netdata support HTML5 notifications, while the
+   dashboard is open in a browser window (no need to be
+   the active one).
+
+   All notifications are now clickable to get to the chart
+   that raised the alarm.
+
+ * improved IoT support!
+
+   netdata builds and runs with musl libc and runs on systems
+   based on busybox.
+
+ * improved containers support!
+
+   netdata runs on alpine linux (a low profile linux distribution
+   used in containers).
+
+ * Dozens of other improvements and bugfixes
+ 
+ 
+netdata (1.3.0) - 2016-08-28
+
+ At a glance:
+
+ - netdata has health monitoring / alarms!
+ - netdata has badges that can be embeded anywhere!
+ - netdata plugins are now written in Python!
+ - new plugins: redis, memcached, nginx_log, ipfs, apache_cache
+
+ IMPORTANT:
+ Since netdata now uses Python plugins, new packages are
+ required to be installed on a system to allow it work.
+ For more information, please check the installation page:
+
+ https://github.com/netdata/netdata/tree/master/installer#installation
+
+ In detail:
+
+ * netdata has alarms!
+
+   Based on the POLL we made on github
+   (https://github.com/netdata/netdata/issues/436),
+   health monitoring was the winner. So here it is!
+
+   netdata now has a poweful health monitoring system embedded.
+   Please check the wiki page:
+
+   https://github.com/netdata/netdata/tree/master/health
+
+ * netdata has badges!
+
+   netdata can generate badges with live information from the
+   collected metrics.
+   Please check the wiki page:
+
+   https://github.com/netdata/netdata/tree/master/web/api/badges
+
+ * netdata plugins are now written in Python!
+
+   Thanks to the great work of Paweł Krupa (@paulfantom), most BASH
+   plugins have been ported to Python.
+
+   The new python.d.plugin supports both python2 and python3 and
+   data collection from multiple sources for all modules.
+
+   The following pre-existing modules have been ported to Python:
+
+    - apache
+    - cpufreq
+    - example
+    - exim
+    - hddtemp
+    - mysql
+    - nginx
+    - phpfm
+    - postfix
+    - sensors
+    - squid
+    - tomcat
+
+   The following new modules have been added:
+
+    - apache_cache
+    - dovecot
+    - ipfs
+    - memcached
+    - nginx_log
+    - redis
+
+ * other data collectors:
+
+    - Thanks to @simonnagl netdata now reports disk space usage.
+
+ * dashboards now transfer a certain settings from server to server
+   when changing servers via the my-netdata menu.
+
+   The settings transferred are the dashboard theme, the online
+   help status and current pan and zoom timeframe of the dashboard.
+
+ * API improvements:
+
+   - reduction functions now support 'min', 'sum' and 'incremental-sum'.
+
+   - netdata now offers a multi-threaded and a single threaded
+     web server (single threaded is better for IoT).
+
+ * apps.plugin improvements:
+
+   - can now run with command line argument 'without-files'
+     to prevent it from enumating all the open files/sockets/pipes
+     of all running processes.
+
+   - apps.plugin now scales the collected values to match the
+     the total system usage.
+
+   - apps.plugin can now report guest CPU usage per process.
+
+   - repeating errors are now logged once per process.
+
+ * netdata now runs with IDLE process priority (lower than nice 19)
+
+ * netdata now instructs the kernel to kill it first when it starves
+   for memory.
+
+ * netdata listens for signals:
+
+   - SIGHUP to netdata instructs it to re-open its log files
+     (new logrotate files added too).
+
+   - SIGUSR1 to netdata saves the database
+
+   - SIGUSR2 to netdata reloads health / alarms configuration
+
+ * netdata can now bind to multiple IPs and ports.
+
+ * netdata now has new systemd service file (it starts as user
+   netdata and does not fork).
+
+ * Dozens of other improvements and bugfixes
+ 
+ 
+netdata (1.2.0) - 2016-05-16
+
+ At a glance:
+
+ - netdata is now 30% faster
+ - netdata now has a registry (my-netdata dashboard menu)
+ - netdata now monitors Linux Containers (docker, lxc, etc)
+
+ IMPORTANT:
+ This version requires libuuid. The package you need is:
+
+  - uuid-dev (debian/ubuntu), or
+  - libuuid-devel (centos/fedora/redhat)
+
+ In detail:
+
+ * netdata is now 30% faster !
+
+   - Patches submitted by @fredericopissarra improved overall
+     netdata performance by 10%.
+
+   - A new improved search function in the internal indexes
+     made all searches faster by 50%, resulting in about
+     20% better performance for the core of netdata.
+
+   - More efficient threads locking in key components
+     contributed to the overal efficiency.
+
+ * netdata now has a CENTRAL REGISTRY !
+
+   The central registry tracks all your netdata servers
+   and bookmarks them for you at the 'my-netdata' menu
+   on all dashboards.
+
+   Every netdata can act as a registry, but there is also
+   a global registry provided for free for all netdata users!
+
+ * netdata now monitors CONTAINERS !
+   
+   docker, lxc, or anything else. For each container it monitors
+   CPU, RAM, DISK I/O (network interfaces were already monitored)
+
+ * apps.plugin: now uses linux capabilities by default
+   without setuid to root
+
+ * netdata has now an improved signal handler
+   thanks to @simonnagl
+
+ * API: new improved CORS support
+
+ * SNMP: counter64 support fixed
+
+ * MYSQL: more charts, about QCache, MyISAM key cache,
+   InnoDB buffer pools, open files
+
+ * DISK charts now show mount point when available
+
+ * Dashboard: improved support for older web browsers
+   and mobile web browsers (thanks to @simonnagl)
+
+ * Multi-server dashboards now allow de-coupled refreshes for
+   each chart, so that if one netdata has a network latency
+   the other charts are not affected
+
+ * Several other minor improvements and bugfixes
+ 
+

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a

-# AM_PROG_INSTALL_STRIP
-# ---------------------
-# One issue with vendor 'install' (even GNU) is that you can't
-# specify the program used to strip binaries.  This is especially
-# annoying in cross-compiling environments, where the build's strip
-# is unlikely to handle the host's binaries.
-# Fortunately install-sh will honor a STRIPPROG variable, so we
-# always use install-sh in "make install-strip", and initialize
-# STRIPPROG with the value of the STRIP variable (set by the user).
-AC_DEFUN([AM_PROG_INSTALL_STRIP],
-[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
-# Installed binaries are usually stripped using 'strip' when the user
-# run "make install-strip".  However 'strip' might not be the right
-# tool to use in cross-compilation environments, therefore Automake
-# will honor the 'STRIP' environment variable to overrule this program.
-dnl Don't test for $cross_compiling = yes, because it might be 'maybe'.

+4. Netdata supports 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`.
+   - `as-collected` sends to backends the metrics as they are collected, in the units they are collected. 
+   So, counters are sent as counters and gauges are sent as gauges, much like all data collectors do. 
+   For example, to calculate CPU utilization in this format, you need to know how to convert kernel ticks to percentage.
 
-   - `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`.**
+   - `average` sends to backends normalized metrics from the netdata database. 
+   In this mode, all metrics are sent as gauges, in the units netdata uses. This abstracts data collection 
+   and simplifies visualization, but you will not be able to copy and paste queries from other sources to convert units. 
+   For example, CPU utilization percentage is calculated by netdata, so netdata will convert ticks to percentage and 
+   send the average percentage to the backend.
 
-   - `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.
+   - `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.
+
+Time-series databases suggest to collect the raw values (`as-collected`). If you plan to invest on building your monitoring around a time-series database and you already know (or you will invest in learning) how to convert units and normalize the metrics in Grafana or other visualization tools, we suggest to use `as-collected`.
+
+If, on the other hand, you just need long term archiving of netdata metrics and you plan to mainly work with netdata, we suggest to use `average`. It decouples visualization from data collection, so it will generally be a lot simpler. Furthermore, if you use `average`, the charts shown in the back-end will match exactly what you see in Netdata, which is not necessarily true for the other modes of operation.

@@ -378,3 +378,5 @@ It can also be changed from the URL, by appending `&prefix=netdata`.
 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.

+# cups.plugin
+
+`cups.plugin` collects Common Unix Printing System (CUPS) metrics.
+
+## Prerequisites
+
+This plugin needs a running local CUPS daemon (`cupsd`). This plugin does not need any configuration.
+
+## Charts
+
+`cups.plugin` provides one common section `destinations` and one section per destination. 
+
+> Destinations in CUPS represent individual printers or classes (collections or pools) of printers (https://www.cups.org/doc/cupspm.html#working-with-destinations)
+
+The section `server` provides these charts:
+
+1. **destinations by state**
+ * idle
+ * printing
+ * stopped
+
+2. **destinations by options**
+ * total
+ * accepting jobs
+ * shared
+
+3. **total job number by status**
+ * pending
+ * processing
+ * held
+
+4. **total job size by status**
+ * pending
+ * processing
+ * held
+
+For each destination the plugin provides these charts:
+
+1. **job number by status**
+ * pending
+ * held
+ * processing
+
+3. **job size by status**
+ * pending
+ * held
+ * processing
+  
+At the moment only job status pending, processing, and held are reported because we do not have a method to collect stopped, canceled, aborted and completed jobs which scales.

 This plugin monitors the disk space usage of mounted disks, under Linux.
 
+Two charts are available for every mount:
+ - Disk Space Usage
+ - Disk Files (inodes) Usage
+
+## configuration
+
+Simple patterns can be used to exclude mounts from showed statistics based on path or filesystem. By default read-only mounts are not displayed. To display them `yes` should be set for a chart instead of `auto`.
+
+```
+[plugin:proc:diskspace]
+    # remove charts of unmounted disks = yes
+    # update every = 1
+    # check for new mount points every = 15
+    # exclude space metrics on paths = /proc/* /sys/* /var/run/user/* /run/user/* /snap/* /var/lib/docker/*
+    # exclude space metrics on filesystems = *gvfs *gluster* *s3fs *ipfs *davfs2 *httpfs *sshfs *gdfs *moosefs fusectl
+    # space usage for all disks = auto
+    # inodes usage for all disks = auto
+```
+
+Charts can be enabled/disabled for every mount separately:
+
+```
+[plugin:proc:diskspace:/]
+    # space usage = auto
+    # inodes usage = auto
+```
+

+Netdata has a [freeipmi](https://www.gnu.org/software/freeipmi/) plugin.
 
 > FreeIPMI provides in-band and out-of-band IPMI software based on the IPMI v1.5/2.0 specification. The IPMI specification defines a set of interfaces for platform management and is implemented by a number vendors for system management. The features of IPMI that most users will be interested in are sensor monitoring, system event monitoring, power control, and serial-over-LAN (SOL).

 It works like this:
 
-A thread is spawn that requests to sleep for 20000 microseconds (20ms).
+A thread is spawned that requests to sleep for 20000 microseconds (20ms).
 When the system wakes it up, it measures how many microseconds have passed.
 The difference between the requested and the actual duration of the sleep, is the idle jitter.
 This is done at most 50 times per second, to ensure we have a good average. 
@@ -11,3 +11,5 @@ This number is useful:
  
  1. in real-time environments, when the CPU jitter can affect the quality of the service (like VoIP media gateways).
  2. in cloud infrastructure, at can pause the VM or container for a small duration to perform operations at the host.

+## Linux power supply
+
+This module monitors various metrics reported by power supply drivers
+on Linux. This allows tracking and alerting on things like remaining
+battery capacity.
+
+Depending on the underlying driver, it may provide the following charts
+and metrics:
+
+1. Capacity: The power supply capacity expressed as a percentage.
+  * capacity\_now
+
+2. Charge: The charge for the power supply, expressed as amphours.
+  * charge\_full\_design
+  * charge\_full
+  * charge\_now
+  * charge\_empty
+  * charge\_empty\_design
+
+3. Energy: The energy for the power supply, expressed as watthours.
+  * energy\_full\_design
+  * energy\_full
+  * energy\_now
+  * energy\_empty
+  * energy\_empty\_design
+
+2. Voltage: The voltage for the power supply, expressed as volts.
+  * voltage\_max\_design
+  * voltage\_max
+  * voltage\_now
+  * voltage\_min
+  * voltage\_min\_design
+
+#### configuration
+
+```
+[plugin:proc:/sys/class/power_supply]
+    # battery capacity = yes
+    # battery charge = no
+    # battery energy = no
+    # power supply voltage = no
+    # keep files open = auto
+    # directory to monitor = /sys/class/power_supply
+```
+
+#### notes
+
+* Most drivers provide at least the first chart. Battery powered ACPI
+compliant systems (like most laptops) provide all but the third, but do
+not provide all of the metrics for each chart.
+
+* Current, energy, and voltages are reported with a _very_ high precision
+by the power\_supply framework.  Usually, this is far higher than the
+actual hardware supports reporting, so expect to see changes in these
+charts jump instead of scaling smoothly.
+
+* If `max` or `full` attribute is defined by the driver, but not a
+corresponding `min` or `empty` attribute, then Netdata will still provide
+the corresponding `min` or `empty`, which will then always read as zero.
+This way, alerts which match on these will still work.

-## Pull Request Checklist for Python Plugins
-
-This is a generic checklist for submitting a new Python plugin for Netdata.  It is by no means comprehensive.
-
-At minimum, to be buildable and testable, the PR needs to include:
-
-* The module itself, following proper naming conventions: `python.d/<module_dir>/<module_name>.chart.py`
-* A README.md file for the plugin under `python.d/<module_dir>`. 
-* The configuration file for the module: `conf.d/python.d/<module_name>.conf`. Python config files are in YAML format, and should include comments describing what options are present. The instructions are also needed in the configuration section of the README.md 
-* A basic configuration for the plugin in the appropriate global config file: `conf.d/python.d.conf`, which is also in YAML format.  Either add a line that reads `# <module_name>: yes` if the module is to be enabled by default, or one that reads `<module_name>: no` if it is to be disabled by default.
-* A line for the plugin in `python.d/Makefile.am` under `dist_python_DATA`.
-* A line for the plugin configuration file in `conf.d/Makefile.am`, under `dist_pythonconfig_DATA`
-* Optionally, chart information in `web/dashboard_info.js`.  This generally involves specifying a name and icon for the section, and may include descriptions for the section or individual charts.

 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.

+## Pull Request Checklist for Python Plugins
+
+This is a generic checklist for submitting a new Python plugin for Netdata.  It is by no means comprehensive.
+
+At minimum, to be buildable and testable, the PR needs to include:
+
+* The module itself, following proper naming conventions: `python.d/<module_dir>/<module_name>.chart.py`
+* A README.md file for the plugin under `python.d/<module_dir>`. 
+* The configuration file for the module: `conf.d/python.d/<module_name>.conf`. Python config files are in YAML format, and should include comments describing what options are present. The instructions are also needed in the configuration section of the README.md 
+* A basic configuration for the plugin in the appropriate global config file: `conf.d/python.d.conf`, which is also in YAML format.  Either add a line that reads `# <module_name>: yes` if the module is to be enabled by default, or one that reads `<module_name>: no` if it is to be disabled by default.
+* A line for the plugin in `python.d/Makefile.am` under `dist_python_DATA`.
+* A line for the plugin configuration file in `conf.d/Makefile.am`, under `dist_pythonconfig_DATA`
+* Optionally, chart information in `web/dashboard_info.js`.  This generally involves specifying a name and icon for the section, and may include descriptions for the section or individual charts.

 # dovecot
 
 This module provides statistics information from Dovecot server.

 Statistics are taken from dovecot socket by executing `EXPORT global` command.
 More information about dovecot stats can be found on [project wiki page.](http://wiki2.dovecot.org/Statistics)
 
+Module isn't compatible with new statistic api (v2.3), but you are still able to use the module with Dovecot v2.3
+by following [upgrading steps.](https://wiki2.dovecot.org/Upgrading/2.3).

 **Requirement:**
 Dovecot UNIX socket with R/W permissions for user netdata or Dovecot with configured TCP/IP socket.

-# Netdata Statsd
+# statsd.plugin
 
 statsd is a system to collect data from any application. 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).

 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.

-This is QoS from my home linux router. Check these features:
+Add the following configuration option in `/etc/netdata.conf`:
+```[plugin:tc]
+        enable show all classes and qdiscs for all interfaces = yes
+```
 
-1. It is real-time (per second updates)
-2. QoS really works in Linux - check that the `background` traffic is squeezed when `surfing` needs it.
+Finally, create `/etc/netdata/tc-qos-helper.conf` with this content:
+```tc_show="class"```

-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.
-
-# You can get the latest version of this script from:
-# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
-
-# This file is supposed to be the same for all GNU packages
-# and recognize all the CPU types, system types and aliases
-# that are meaningful with *any* GNU software.
-# Each package is responsible for reporting which valid configurations
-# it does not support.  The user should be able to distinguish
-# a failure to support a valid configuration from a meaningless
-# configuration.
-
-# The goal of this file is to map all the various variations of a given
-# machine specification into a single specification in the form:
-#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
-# It is wrong to echo any other type of specification.

-\`configure' configures netdata 1.11.1_rolling to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:

-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

+- init.d script 
+- run-time dependency on python ordereddict backport
+- patch for netdata python.d plugin to work with older python
+- crude hack of notification script to work with bash 3 (email and syslog only, one destination,

+<details markdown="1"><summary>The daemon configuration file is read from `/etc/netdata/netdata.conf`.</summary>
+Depending on your installation method, Netdata will have been installed either directly under `/`, or under `/opt/netdata`. The paths mentioned here and in the documentation in general assume that your installation is under `/`. If it is not, you will find the exact same paths under `/opt/netdata` as well. (i.e. `/etc/netdata` will be `/opt/netdata/etc/netdata`).</details>
 
-The daemon configuration file is read from `/etc/netdata/netdata.conf`.
+This config file **is not needed by default**. Netdata works fine out of the box without it. But it does allow you to adapt the general behavior of Netdata, in great detail. You can find all these settings, with their default values, by accessing the URL `https://netdata.server.hostname:19999/netdata.conf`. For example check the configuration file of [netdata.firehol.org](http://netdata.firehol.org/netdata.conf). HTTP access to this file is limited by default to private IPs, via the [web server access lists](../../web/server/#access-lists).
 
-In this file you can configure all aspects of netdata. Netdata provides configuration settings for plugins and charts found when started. You can find all these settings, with their default values, by accessing the URL `https://netdata.server.hostname:19999/netdata.conf`. For example check the configuration file of [netdata.firehol.org](http://netdata.firehol.org/netdata.conf).

-The configuration file has sections stated with `[section]`. There will be the following sections:
-
-1. `[global]` for global netdata daemon options
-2. `[plugins]` for controlling which plugins the netdata will use
-3. `[plugin:NAME]` one such section for each plugin enabled
-4. `[CHART_NAME]` once such section for each chart defined
+1. `[global]` to [configure](#global-section-options) the [netdata daemon](../).
+2. `[web]` to [configure the web server](../../web/server).
+3. `[plugins]` to [configure](#plugins-section-options) which [collectors](../../collectors) to use and PATH settings.
+4. `[health]` to [configure](#health-section-options) general settings for [health monitoring](../../health)
+5. `[registry]` for the [netdata registry](../../registry). 
+6. `[backend]` to set up [streaming and replication](../../streaming) options.
+7. `[statsd]` for the general settings of the [stats.d.plugin](../../collectors/statsd.plugin). 
+8. `[plugin:NAME]` sections for each collector plugin, under the comment [Per plugin configuration](#per-plugin-configuration).
+9. `[CHART_NAME]` sections for each chart defined, under the comment [Per chart configuration](#per-chart-configuration).
 
 The configuration file is a `name = value` dictionary. Netdata will not complain if you set options unknown to it. When you check the running configuration by accessing the URL `/netdata.conf` on your netdata server, netdata will add a comment on settings it does not currently use.
 
-### [global] section options
-
-
-setting | default | info
-:------:|:-------:|:----
-hostname|auto-detected|The hostname of the computer running netdata.
-history|3600|The number of entries the netdata daemon will by default keep in memory for each chart dimension. This setting can also be configured per chart. Check [Memory Requirements](../../database/#netdata-database) for more information.
-config directory|`/etc/netdata`|The directory configuration files are kept.
-plugins directory|`/usr/libexec/netdata/plugins.d`|The directory plugin programs are kept. This setting supports multiple directories, space separated. If any directory path contains spaces, enclose it in single or double quotes.
-web files directory|`/usr/share/netdata/web`|The directory the web static files are kept.
-cache directory|`/var/cache/netdata`|The directory the memory database will be stored if and when netdata exits. Netdata will re-read the database when it will start again, to continue from the same point.
-log directory|`/var/log/netdata`|The directory in which the [log files](../#log-files) are kept.
-host access prefix|*empty*|This is used in docker environments where /proc, /sys, etc have to be accessed via another path. You may also have to set SYS_PTRACE capability on the docker for this work. Check [issue 43](https://github.com/netdata/netdata/issues/43).
-debug flags|0x00000000|Bitmap of debug options to enable. For more information check [Tracing Options](../#debugging).
-memory deduplication (ksm)|yes|When set to `yes`, netdata will offer its in-memory round robin database to kernel same page merging (KSM) for deduplication. For more information check [[Memory Deduplication - Kernel Same Page Merging - KSM]]
-debug log|`/var/log/netdata/debug.log`|The filename to save debug information. This file will not be created is debugging is not enabled. You can also set it to `syslog` to send the debug messages to syslog, or `none` to disable this log. For more information check [Tracing Options](../#debugging).
-error log|`/var/log/netdata/error.log`|The filename to save error messages for netdata daemon and all plugins (`stderr` is sent here for all netdata programs, including the plugins). You can also set it to `syslog` to send the errors to syslog, or `none` to disable this log.
-access log|`/var/log/netdata/access.log`|The filename to save the log of web clients accessing netdata charts. You can also set it to `syslog` to send the access log to syslog, or `none` to disable this log.
-memory mode|save|When set to `save` netdata will save its round robin database on exit and load it on startup. When set to `map` the cache files will be updated in real time (check `man mmap` - do not set this on systems with heavy load or slow disks - the disks will continuously sync the in-memory database of netdata). When set to `ram` the round robin database will be temporary and it will be lost when netdata exits.
-update every|1|The frequency in seconds, for data collection. For more information see [Performance](../../doc/Performance.md#netdata-performance).
-run as user|`netdata`|The user netdata will run as.
-web files owner|`netdata`|The user that owns the web static files. Netdata will refuse to serve a file that is not owned by this user, even if it has read access to that file. If the user given is not found, netdata will only serve files owned by user given in `run as user`.
-http port listen backlog|100|The port backlog. Check `man 2 listen`.
-default port|19999|The default port to listen for web clients.
-bind to|`*`|The IP address and port to listen to. This is a space separated list of IPv4 or IPv6 address and ports. The default will bind to all IP addresses. Example: `bind to = 127.0.0.1:19999 10.11.12.1:19998 [::1]:19999`.
-disconnect idle web clients after seconds|60|The time in seconds to disconnect web clients after being totally idle.
-enable web responses gzip compression|yes|When set to `yes`, netdata web responses will be GZIP compressed, if the web client accepts such responses.
-
-##### netdata process priority
-
-By default, netdata runs with the `idle` process scheduler, which assigns CPU resources to netdata, only when the system has such resources to spare.
-
-The following `netdata.conf` settings control this:
-
-```
-[global]
-    process scheduling policy = idle
-    process scheduling priority = 0
-    process nice level = 19
-```
-
-The policies supported by netdata are `idle` (the netdata default), `other` (also as `nice`), `batch`, `rr`, `fifo`. netdata also recognizes `keep` and `none` to keep the current settings without changing them.
-
-For `other`, `nice` and `batch`, the setting `process nice level = 19` is activated to configure the nice level of netdata. Nice gets values -20 (highest) to 19 (lowest).
-
-For `rr` and `fifo`, the setting `process scheduling priority = 0` is activated to configure the priority of the relative scheduling policy. Priority gets values 1 (lowest) to 99 (highest).
-
-For the details of each scheduler, see `man sched_setscheduler` and `man sched`.
+## Applying changes
 
-When netdata is running under systemd, it can only lower its priority (the default is `other` with `nice level = 0`). If you want to make netdata to get more CPU than that, you will need to set in `netdata.conf`:
+After `netdata.conf` has been modified, netdata needs to be restarted for changes to apply:
 
-```
-[global]
-    process scheduling policy = keep
+```bash
+sudo service netdata restart
 ```
 
-and edit `/etc/systemd/system/netdata.service` and add:
+If the above does not work, try the following:
 
-```
-CPUSchedulingPolicy=other | batch | idle | fifo | rr
-CPUSchedulingPriority=99
-Nice=-10
+```bash
+sudo killall netdata; sleep 10; sudo netdata
 ```
 
+Please note that your data history will be lost if you have modified `history` parameter in section `[global]`.
 
-### [plugins] section options
+## Sections
 
-In this section there will be a boolean (`yes`/`no`) option for each plugin. Additionally, there will be the following options:
+### [global] section options
 
 setting | default | info
 :------:|:-------:|:----
-checks|no|This is a debugging plugin for the internal latency of netdata.
-enable running new plugins|yes|When set to `yes`, netdata will enable plugins not configured specifically for them. Setting this to `no` will disable all plugins you have not set to `yes` explicitly.
-check for new plugins every|60|The time in seconds to check for new plugins in the plugins directory. This allows having other applications dynamically creating plugins for netdata.
-
-## Netdata Plugins
-
-The configuration options for plugins appear in sections following the pattern `[plugin:NAME]`.
-

+### [web] section options
+
+Refer to the [web server documentation](../../web/server)
 
+### [plugins] section options
 
-### External Plugins
+In this section you will see be a boolean (`yes`/`no`) option for each plugin (e.g. tc, cgroups, apps, proc etc.). Note that the configuration options in this section for the orchestrator plugins `python.d`, `charts.d` and `node.d` control **all the modules** written for that orchestrator. For instance, setting `python.d = no` means that all Python modules under `collectors/python.d.plugin` will be disabled.  
 
-External plugins will have only 2 options at `netdata.conf`:
+Additionally, there will be the following options:
 
 setting | default | info
 :------:|:-------:|:----
-update every|the value of `[global].update every` setting|The frequency in seconds the plugin should collect values. For more information check [Performance](../../doc/Performance.md#netdata-performance).
-command options|*empty*|Additional command line options to pass to the plugin. 
-
-External plugins that need additional configuration may support a dedicated file in `/etc/netdata`. Check their documentation.
-
----
-
-## A note about netdata.conf
-
-This config file is not needed by default. You can just touch it (to be empty) to get rid of the error message displayed when missing.
-
-The whole idea came up when I was evaluating the documentation involved in maintaining a complex configuration system. My 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.
+PATH environment variable | `auto-detected` | 
+PYTHONPATH environment variable | | Used to set a custom python path
+enable running new plugins | `yes` | When set to `yes`, netdata will enable detected plugins, even if they are not configured explicitly. Setting this to `no` will only enable plugins explicitly configirued in this file with a `yes` 
+check for new plugins every | 60 | The time in seconds to check for new plugins in the plugins directory. This allows having other applications dynamically creating plugins for netdata.
+checks | `no` | This is a debugging plugin for the internal latency 
 
-I concluded then that configuring software like that is a waste for 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 devs and the users.
+### [health] section options
 
-So, I did this:
+This section controls the general behavior of the health monitoring capabilities of Netdata. 
 
-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)
+Specific alarms are configured in per-collector config files under the `health.d` directory. For more info, see [health monitoring](../../health/#health-monitoring). 
 
-### Why this works?
+[Alarm notifications](../../health/notifications/#netdata-alarm-notifications) are configured in `health_alarm_notify.conf`. 
 
-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. 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.
+setting | default | info
+:------:|:-------:|:----
+enabled | `yes` | Set to `no` to disable all alarms and notifications
+in memory max health log entries | 1000 | Size of the alarm history held in RAM
+script to execute on alarm | `/usr/libexec/netdata/plugins.d/alarm-notify.sh` | The script that sends alarm notifications. 
+stock health configuration directory | `/usr/lib/netdata/conf.d/health.d` | Contains the stock alarm configuration files for each collector
+health configuration directory | `/etc/netdata/health.d` | The directory containing the user alarm configuration files, to override the stock configurations
+run at least every seconds | `10` | Controls how often all alarm conditions should be evaluated. 
+postpone alarms during hibernation for seconds | `60` | Prevents false alarms. May need to be increased if you get alarms during hibernation.
+rotate log every lines | 2000 | Controls the number of alarm log entries stored in `<lib directory>/health-log.db`, where <lib directory> is the one configured in the [[global] section](#global-section-options)
 
-### limiting access to netdata.conf
+### [registry] section options
 
-netdata v1.9+ limit by default access to `http://your.netdata.ip:19999/netdata.conf` to private IP addresses. This is controlled by this settings:
+To understand what this section is and how it should be configured, please refer to the [registry documentation](../../registry). 
 
-```
-[web]
-	allow netdata.conf from = localhost fd* 10.* 192.168.* 172.16.* 172.17.* 172.18.* 172.19.* 172.20.* 172.21.* 172.22.* 172.23.* 172.24.* 172.25.* 172.26.* 172.27.* 172.28.* 172.29.* 172.30.* 172.31.*
-```
+### [backend]
 
-The IPs listed are all the private IPv4 addresses, including link local IPv6 addresses.
+Refer to the [streaming and replication](../../streaming) documentation.
 
-> Keep in mind that connections to netdata API ports are filtered by `[web].allow connections from`. So, IPs allowed by `[web].allow netdata.conf from` should also be allowed by `[web].allow connections from`.
+### Per plugin configuration
 
+The configuration options for plugins appear in sections following the pattern `[plugin:NAME]`.
 
-## netdata simple patterns
+#### Internal plugins
 
-Unix prefers regular expressions. But they are just too hard, too cryptic to use, write and understand.
+Most internal plugins will provide additional options. Check [Internal Plugins](../../collectors/) for more information.
 
-So, netdata supports [simple patterns](../../libnetdata/simple_pattern/). 
+#### External plugins
 
-## Applying changes
+External plugins will have only 2 options at `netdata.conf`:
 
-After `netdata.conf` has been modified, netdata needs to be restarted for changes to apply:
+setting | default | info
+:------:|:-------:|:----
+update every|the value of `[global].update every` setting|The frequency in seconds the plugin should collect values. For more information check [Performance](../../docs/Performance.md#performance).
+command options|*empty*|Additional command line options to pass to the plugin. 
 
-```bash
-sudo service netdata restart
-```
+External plugins that need additional configuration may support a dedicated file in `/etc/netdata`. Check their documentation.
 
-If the above does not work, try the following:
+### Per chart configuration
 
-```bash
-sudo killall netdata; sleep 10; sudo netdata
-```
+In this section you will a separate subsection for each chart shown on the dashboard. You can control all aspects of a specific chart here. You can understand what each option does by reading [how charts are defined](../../collectors/plugins.d/#chart). If you don't know how to find the name of a chart, you can learn about it [here](../../docs/Charts.md).
 
-Please note that your data history will be lost if you have modified `history` parameter in section `[global]`.

-# Netdata Performance
-
-Netdata performance is affected by:
-
-**Data collection**
-- the number of charts for which data are collected
-- the number of plugins running
-- the technology of the plugins (i.e. BASH plugins are slower than binary plugins)
-- the frequency of data collection
-
-You can control all the above.
-
-**Web clients accessing the data**
-- the duration of the charts in the dashboard
-- the number of charts refreshes requested
-- the compression level of the web responses
-
----
-
-## Netdata Daemon
-
-For most server systems, with a few hundred charts and a few thousand dimensions, the netdata daemon, without any web clients accessing it, should not use more than 1% of a single core.
-
-To prove netdata scalability, check issue [#1323](https://github.com/netdata/netdata/issues/1323#issuecomment-265501668) where netdata collects 95.000 metrics per second, with 12% CPU utilization of a single core!
-
-In embedded systems, if the netdata daemon is using a lot of CPU without any web clients accessing it, you should lower the data collection frequency. To set the data collection frequency, edit `/etc/netdata/netdata.conf` and set `update_every` to a higher number (this is the frequency in seconds data are collected for all charts: higher number of seconds = lower frequency, the default is 1 for per second data collection). You can also set this frequency per module or chart. Check the **[[Configuration]]** section.
-
-## Plugins
-
-If a plugin is using a lot of CPU, you should lower its update frequency, or if you wrote it, re-factor it to be more CPU efficient. Check **[[External Plugins]]** for more details on writing plugins.
-
-## CPU consumption when web clients are accessing dashboards
-
-Netdata is very efficient when servicing web clients. On most server platforms, netdata should be able to serve **1800 web client requests per second per core** for auto-refreshing charts.
-
-Normally, each user connected will request less than 10 chart refreshes per second (the page may have hundreds of charts, but only the visible are refreshed). So you can expect 180 users per CPU core accessing dashboards before having any delays.
-
-Netdata runs with the lowest possible process priority, so even if 1000 users are accessing dashboards, it should not influence your applications. CPU utilization will reach 100%, but your applications should get all the CPU they need.
-
-To lower the CPU utilization of netdata when clients are accessing the dashboard, set `web compression level = 1`, or disable web compression completely by setting `enable web responses gzip compression = no`. Both settings are in the `[web]` section.
-
-
-## Monitoring a heavy loaded system
-
-Netdata, while running, does not depend on disk I/O (apart its log files and `access.log` is written with buffering enabled and can be disabled). Some plugins that need disk may stop and show gaps during heavy system load, but the netdata daemon itself should be able to work and collect values from `/proc` and `/sys` and serve web clients accessing it.
-
-Keep in mind that netdata saves its database when it exits and loads it back when restarted. While it is running though, its DB is only stored in RAM and no I/O takes place for it.
-
-
-## Running netdata in embedded devices
-
-Embedded devices usually have very limited CPU resources available, and in most cases, just a single core.
-
-We suggest to do the following:
-
-#### external plugins
-
- `charts.d.plugin` and `apps.plugin`, each consumes twice the CPU resources of the netdata daemon.
-
- If you don't need them, disable them (edit `/etc/netdata/netdata.conf` and search for the plugins section).
-
- If you need them, increase their `update every` value (again in `/etc/netdata/netdata.conf`), so that they do not run that frequently.
-
-#### internal plugins
-
-If netdata is still using a lot of CPU, lower its update frequency. Going from per second updates, to once every 2 seconds updates, will cut the CPU resources of all netdata programs **in half**, and you will still have very frequent updates.
-
-If the CPU of the embedded device is too weak, try setting even lower update frequency. Experiment with `update every = 5` or `update every = 10` (higher number = lower frequency), until you get acceptable results.
-
-#### Single threaded web server
-
-Normally, netdata spawns a thread for each web client. This allows netdata to utilize all the available cores for servicing chart refreshes. You can however disable this feature and serve all charts one after another, using a single thread / core. This will might lower the CPU pressure on the embedded device. To enable the single threaded web server, edit `/etc/netdata/netdata.conf` and set `mode = single-threaded` in the `[web]` section.

-# Why Netdata
-
-![image8](https://cloud.githubusercontent.com/assets/2662304/14253735/536f4580-fa95-11e5-9f7b-99112b31a5d7.gif)
-
-## Netdata is unique!
-
-The following is an animated GIF showing **netdata**'s ability to monitor QoS. The timings of this animation have not been altered, this is the real thing:
-
-![animation5](https://cloud.githubusercontent.com/assets/2662304/12373715/0da509d8-bc8b-11e5-85cf-39d5234bf976.gif)
-
-Check the details on this animation:
-
-1. At the beginning the charts auto-refresh, in real-time
-2. Charts can be dragged and zoomed (either mouse or touch)
-3. You pan or zoom one, the others follow
-4. Mouse over on one, selects the same timestamp on all
-5. Dimensions can be enabled or disabled
-6. All refreshes are instant (an 8 year old core-2 duo computer was used to record this)
-
-There are a lot of excellent open source tools for collecting and visualizing performance metrics. Check for example [collectd](https://collectd.org/), [OpenTSDB](http://opentsdb.net/), [influxdb](https://influxdata.com/), [Grafana](http://grafana.org/), etc.
-
-So, why **netdata**?
-
-Well, **netdata** has a quite different approach.
-
-## Simplicity
-
-> Most monitoring solutions require endless configuration of whatever imaginable. Well, this is a linux box. Why do we need to configure every single metric we need to monitor. Of course it has a CPU and RAM and a few disks, and ethernet ports, it might run a firewall, a web server, or a database server and so on. Why do we need to configure all these metrics?
-
-**Netdata** has been designed to auto-detect everything. Of course you can enable, tweak or disable things. But by default, if **netdata** can retrieve `/server-status` from an web server you run on your linux box, it will automatically collect all performance metrics. This happens for apache, squid, nginx, mysql, opensips, etc. It will also automatically collect all available system values for CPU, memory, disks, network interfaces, QoS (with labels if you also use [FireQOS](http://firehol.org)), etc. Even for applications that do not offer performance metrics, it will automatically group the whole process tree and provide metrics like CPU usage, memory allocated, opened files, sockets, disk activity, swap activity, etc per application group.
-
-Netdata supports plenty of [configuration](../daemon/config/). However, we have done everything we can to allow netdata to auto-detect as much as possible.
-
-Even netdata plugins are designed to support configuration-less operation. So, you just install and run netdata. You will need to configure something only if it cannot be auto-detected.
-
-> Take any performance monitoring solution and try to troubleshoot a performance problem. At the end of the day you will have to ssh to the server to understand what exactly is happening. You will have to use `iostat`, `iotop`, `vmstat`, `top`, `iperf`, `ethtool` and probably a few dozen more console tools to figure it out.
-
-With **netdata**, this need is eliminated significantly. Of course you will ssh. Just not for monitoring performance.
-
-If you install **netdata** you will prefer it over the console tools. **Netdata** visualizes the data, while the console tools just show their values. The detail is the same - I have spent pretty much time reading the source code of the console tools, to figure out what needs to do done in netdata, so that the data, the values, will be the same. Actually, **netdata** is more precise than most console tools, it will interpolate all collected values to second boundary, so that even if something took a few microseconds more to be collected, netdata will correctly estimate the per second value.
-
-**Netdata** visualizes data in ways you cannot even imagine on a console. It allows you to see the present in real-time, much like the console tools, but also the recent past, compare different metrics with each other, zoom in to see the recent past in detail, or zoom out to have a helicopter view of what is happening in longer durations, build custom dashboards with just the charts you need for a specific purpose.
-
-Most engineers that install netdata, ssh to the server to tweak system or application settings and at the same time they monitor the result of the new settings in **netdata** on their browser.
-
-## Per second data collection and visualization
-
-**Per second data collection and visualization** is usually only available in dedicated console tools, like `top`, `vmstat`, `iostat`, etc. Netdata brings per second data collection and visualization to all applications, accessible through the web.
-
-*You are not convinced per second data collection is important?*
-**Click** this image for a demo:
-
-[![image](https://cloud.githubusercontent.com/assets/2662304/12373555/abd56f04-bc85-11e5-9fa1-10aa3a4b648b.png)](http://netdata.firehol.org/demo2.html)
-
-## Realtime monitoring
-
-> Any performance monitoring solution that does not go down to per second collection and visualization of the data, is useless. It will make you happy to have it, but it will not help you more than that. 
-
-Visualizing the present in **real-time and in great detail**, is the most important value a performance monitoring solution should provide. The next most important is the last hour, again per second. The next is the last 8 hours and so on, up to a week, or at most a month. In my 20+ years in IT, I needed just once or twice to look a year back. And this was mainly out of curiosity.
-
-Of course real-time monitoring requires resources. **netdata** is designed to be very efficient:
-
-1. collecting performance data is a repeating process - you do the same thing again and again. **Netdata** has been designed to learn from each iteration, so that the next one will be faster. It learns the sizes of files (it even keeps them open when it can), the number of lines and words per line they contain, the sizes of the buffers it needs to process them, etc. It adapts, so that everything will be as ready as possible for the next iteration.
-2. internally, it uses hashes and indexes (b-trees), to speed up lookups of metrics, charts, dimensions, settings.
-3. it has an in-memory round robin database based on a custom floating point number that allows it to pack values and flags together, in 32 bits, to lower its memory footprint.
-4. its internal web server is capable of generating JSON responses from live performance data with speeds comparable to static content delivery (it does not use `printf`, it is actually 11 times faster than in generating JSON compared to `printf`).
-
-**Netdata** will use some CPU and memory, but it **will not produce any disk I/O at all**, apart its logs (which you can disable if you like).
-
-Most servers should have plenty of CPU resources (I consider a hardware upgrade or application split when a server averages around 40% CPU utilization at the peak hour). Even if a server has limited CPU resources available, you can just lower the data collection frequency of **netdata**. Going from per second to every 2 seconds data collection, will cut the **netdata** CPU requirements in half and you will still get charts that are just 2 seconds behind.
-
-The same goes for memory. If you just keep an hour of data (which is perfect for performance troubleshooting), you will most probably need 15-20MB. You can also enable the kernel de-duper (Kernel Same-Page Merging) and **netdata** will offer to it all its round robin database. KSM can free 20-60% of the memory used by **netdata** (guess why: there are a lot of metrics that are always zero or just constant).
-
-When netdata runs on modern computers (even on CELERON processors), most chart queries are replied in less than 3 milliseconds! **Not seconds, MILLISECONDS!** Less than 3 milliseconds for calculating the chart, generating JSON text, compressing it and sending it to your web browser. Timings are logged in netdata's `access.log` for you to examine.
-
-Netdata is written in plain `C` and the key system plugins are written in `C` too. Its speed can only be compared to the native console system administration tools.
-
-You can also stress test your netdata installation by running the script `tests/stress.sh` found in the distribution. Most modern server hardware can serve more than 300 chart refreshes per second per core. A raspberry pi 2, can serve 300+ chart refreshes per second utilizing all of its 4 cores.
-
-
-## No disk I/O at all
-
-Netdata does not use any disk I/O, apart from its logs and even these can be disabled.
-
-Netdata will use some memory (you size it, check [[Memory Requirements]] and CPU (below 2% of a single core for the daemon, plugins may require more, check [[Performance]]), but normally your systems should have plenty of these resources available and spare.
-
-The design goal of **NO DISK I/O AT ALL** effectively means netdata will not disrupt your applications.
-
-## No root access
-
-You don't need to run netdata as root. If started as root, netdata will switch to the `netdata` user (or any other user given in its configuration or command line argument).
-
-There are a few plugins that in order to collect values need root access. These (and only these) are setuid to root.
-
-## Visualizes QoS
-
-Netdata visualizes `tc` QoS classes automatically. If you also use FireQOS, it will also collect interface and class names.
-
-Check this animated GIF (generated with [ScreenToGif](https://github.com/NickeManarin/ScreenToGif)):
-
-![animation5](https://cloud.githubusercontent.com/assets/2662304/12373715/0da509d8-bc8b-11e5-85cf-39d5234bf976.gif)
-
-## Embedded web server
-
-> Most solutions require dedicated servers to actually use the monitoring console. To my perspective, this is totally unneeded for performance monitoring. All of us have a spectacular tool on our desktops, that allows us to connect in real time to any server in the world: **the web browser**. It shouldn't be so hard to use the same tool to connect in real-time to all our servers.
-
-With **netdata**, there is no need to centralize anything for performance monitoring. You view everything directly from their source. No need to run something else to access netdata. Of course you can use a firewall, or a reverse proxy, to limit access to it. But for most systems, inside your DMZ, just running it will be enough.
-
-Still, with **netdata** you can build dashboards with charts from any number of servers. And these charts will be connected to each other much like the ones that come from the same server. You will hover on one and all of them will show the relative value for the selected timestamp. You will zoom or pan one and all of them will follow. **Netdata** achieves that because the logic that connects the charts together is at the browser, not the server, so that all charts presented on the same page are connected, no matter where they come from.
-
-## Performance monitoring, scaled properly
-
-"Properly"? What is "properly"?
-
-We know software solutions can **scale up** (i.e. you replace its resources with bigger ones), or **scale out** (i.e. you add more smaller resources to it). In both cases, to get more of it, you need to supply **more resources**.
-
-So, what is "scaled properly"?
-
-Traditionally, monitoring solutions centralize all metric data to provide unified dashboards across all servers. So, you install agents on all your servers to collect system and application metrics which are then sent to a central place for storage and processing. Depending on the solution you use, the central place can either **scale up** or **scale out** (or a mix of the two).
-
-"Scaled properly" is something completely different. "Scaled properly" minimizes the need for a "central place", so that **there is nothing to be scaled**!
-
-Wait a moment! You cannot take out the "central place" of a monitoring solution!
-
-Yes, we can! well... most of it, but before explaining how, let's see what happens today:
-
-Monitoring solutions are a key component for any online service. These solutions usually consume considerable amount of resources. This is true for both "scale-up" and "scale-out" solutions. These resources require maintenance and administration too. To balance the resources required, these monitoring solutions follow a few simple rules:
-
-1. The number of metrics collected per server is limited. They collect CPU, RAM, DISK, NETWORK metrics and a few application metrics.
-
-2. The data collection frequency of each metric is also very low, at best it is once every 10 or 15 seconds, at worst every 5 or 10 mins.
-
-Due to all the above, most centralized monitoring solutions are usually good for alarms and **statistics of past performance**. The alarms usually trigger every 1 to 5 minutes and you get a few low-resolution charts about the past performance of your servers.
-
-Well... there is something wrong in this approach! Can you see it?
-
-Let's see the netdata approach:
-
-1. Data collection happens **per second**. This allows true real-time performance monitoring.
-
-2. **Thousands of metrics** per server and application are collected, **every single second**. The number of metrics collected is not a problem.
- 
-3. Data do not leave the server they are collected. Data are not centralized, so the need for a huge central place that will process and store gazillions of data is not needed.
-
-   > Ok, I hear a few of you complaining already - you will find out... patience...
-
-4. netdata does not use any DISK I/O while running (apart its log files - and even these can be disabled) and netdata runs with the lowest possible process priority, so that **your applications will never be affected by it**.
-
-5. Each netdata is standalone. Your web browser connects directly to each server to present real-time dashboards. The charts are so snappy, so real-time, so fast that we can call netdata, **a console killer for performance monitoring**.
-
-The charting libraries **netdata** uses, are the fastest possible ([Dygraphs](http://dygraphs.com/) do make the difference!) and **netdata** respects browser resources. Data are just rendered on a canvas. No processing in javascript at all.
-
-6. netdata is very efficient: just 2% of a single core is required and some RAM, and you can actually control how much of both you want to allocate to it.
-
-
-Server side, chart data generation scales pretty well. You can expect 400+ chart refreshes per second per core on modern hardware. For a page with 10 charts visible (the page may have hundreds, but only the visible are refreshed), just a tiny fraction of a single CPU core will be used for servicing them. Even these refreshes stop when you switch tabs on your browser, you focus on another window, scroll to a part of the page without charts, zoom or pan a chart. And of course the **netdata** server runs with the lowest possible process priority, so that your production environment, your applications, will not be slowed down by the netdata server.
-
-7. netdata dashboards can be multi-server (check: [http://my-netdata.io](http://my-netdata.io)) - your browser connects to each netdata server directly.
-
-So, using netdata, your monitoring infrastructure is embedded on each server, limiting significantly the need of additional resources. netdata is very resource efficient and utilizes server resources that already exist and are spare (on each server).
-
-Of course, there are a few issues that need to be addressed with this approach:
-
-1. We need an index of all netdata installations we have
-2. We need a place to handle notifications and alarms
-3. We need a place to save statistics of past performance
-
-Our approach uses the netdata [registry](../registry/). The registry solves the problem of maintaining a list of all the netdata installations we have. It does this transparently, without any configuration. It tracks the netdata servers your web browser has visited and bookmarks them at the `my-netdata` menu.
-
-Every netdata can be a registry. You can use the global one we provided for free, or pick one of your netdata servers and turn it to a registry for your network.

-netdata is a **very efficient** server performance monitoring solution. When running in server hardware, it can collect thousands of system and application metrics **per second** with just 1% CPU utilization of a single core. Its web server responds to most data requests in about **half a millisecond** making its web dashboards spontaneous, amazingly fast!
-
-netdata can also be a very efficient real-time monitoring solution for **IoT devices** (RPIs, routers, media players, wifi access points, industrial controllers and sensors of all kinds). Netdata will generally run everywhere a Linux kernel runs (and it is glibc and [musl-libc](https://www.musl-libc.org/) friendly).
-
-You can use it as both a data collection agent (where you pull data using its API), for embedding its charts on other web pages / consoles, but also for accessing it directly with your browser to view its dashboard.
-
-The netdata web API already provides **reduce** functions allowing it to report **average** and **max** for any timeframe. It can also respond in many formats including JSON, JSONP, CSV, HTML. Its API is also a **google charts** provider so it can directly be used by google sheets, google charts, google widgets.

-
-Although netdata has been significantly optimized to lower the CPU and RAM resources it consumes, the plethora of data collection plugins may be inappropriate for weak IoT devices.
-
-> keep in mind that netdata on RPi 2 and 3 does not require any tuning. The default settings will be good. The following tunables apply only when running netdata on RPi 1 or other very weak IoT devices.
-
-Here are a few tricks to control the resources consumed by netdata:
-
-## 1. Disable External plugins
-
-External plugins can consume more system resources than the netdata server. Disable the ones you don't need.
-
-Edit `/etc/netdata/netdata.conf`, find the `[plugins]` section:
-
-```
-[plugins]
-	proc = yes
-
-	tc = no
-	idlejitter = no
-	cgroups = no
-	checks = no
-	apps = no
-	charts.d = no
-	node.d = no
-
-	plugins directory = /usr/libexec/netdata/plugins.d
-	enable running new plugins = no
-	check for new plugins every = 60
-```
-
-In detail:
-
-plugin|description
-:---:|:---------
-`proc`|the internal plugin used to monitor the system. Normally, you don't want to disable this. You can disable individual functions of it at the next section.
-`tc`|monitoring network interfaces QoS (tc classes)
-`idlejitter`|internal plugin (written in C) that attempts show if the systems starved for CPU. Disabling it will eliminate a thread.
-`cgroups`|monitoring linux containers. Most probably you are not going to need it. This will also eliminate another thread.
-`checks`|a debugging plugin, which is disabled by default.
-`apps`|a plugin that monitors system processes. It is very complex and heavy (heavier than the netdata daemon), so if you don't need to monitor the process tree, you can disable it.
-`charts.d`|BASH plugins (squid, nginx, mysql, etc). This is again a heavy plugin.
-`node.d`|node.js plugin, currently used for SNMP data collection and monitoring named (the name server).
-
-For most IoT devices, you can disable all plugins except `proc`. For `proc` there is another section that controls which functions of it you need. Check the next section.
-
----
-
-## 2. Disable internal plugins
-
-In this section you can select which modules of the `proc` plugin you need. All these are run in a single thread, one after another. Still, each one needs some RAM and consumes some CPU cycles.
-
-```
-[plugin:proc]
-	# /proc/net/dev = yes                       # network interfaces
-	# /proc/diskstats = yes                     # disks
-	# /proc/net/snmp = yes                      # generic IPv4
-	# /proc/net/snmp6 = yes                     # generic IPv6
-	# /proc/net/netstat = yes                   # TCP and UDP
-	# /proc/net/stat/conntrack = yes            # firewall
-	# /proc/net/ip_vs/stats = yes               # IP load balancer
-	# /proc/net/stat/synproxy = yes             # Anti-DDoS
-	# /proc/stat = yes                          # CPU, context switches
-	# /proc/meminfo = yes                       # Memory
-	# /proc/vmstat = yes                        # Memory operations
-	# /proc/net/rpc/nfsd = yes                  # NFS Server
-	# /proc/sys/kernel/random/entropy_avail = yes # Cryptography
-	# /proc/interrupts = yes                    # Interrupts
-	# /proc/softirqs = yes                      # SoftIRQs
-	# /proc/loadavg = yes                       # Load Average
-	# /sys/kernel/mm/ksm = yes                  # Memory deduper
-	# netdata server resources = yes            # netdata charts
-```
-

-
-## 3. Disable logs
-
-Normally, you will not need them. To disable them, set:
-
-```
-[global]
-	debug log = none
-	error log = none
-	access log = none
-```
-
----
-
-## 4. Set memory mode to RAM
-
-Setting the memory mode to `ram` will disable loading and saving the round robin database. This will not affect anything while running netdata, but it might be required if you have very limited storage available.
-
-```
-[global]
-	memory mode = ram
-```
-
----
-
-## 5. CPU utilization
-
-If after disabling the plugins you don't need, netdata still uses a lot of CPU without any clients accessing the dashboard, try lowering its data collection frequency. Going from "once per second" to "once every two seconds" will not have a significant difference on the user experience, but it will cut the CPU resources required **in half**.
-
-To set the update frequency, edit `/etc/netdata/netdata.conf` and set:
-
-```
-[global]
-      update every = 2
-```
-
-You may have to increase this to 5 or 10 if the CPU of the device is weak.
-
-Keep in mind this will also force dashboard chart refreshes to happen at the same rate. So increasing this number actually lowers data collection frequency but also lowers dashboard chart refreshes frequency.
-
-This is a dashboard on a device with `[global].update every = 5` (this device is a media player and is now playing a movie):		
-		
-![pi1](https://cloud.githubusercontent.com/assets/2662304/15338489/ca84baaa-1c88-11e6-9ab2-118208e11ce1.gif)
-
----
-
-## 6. Lower memory requirements
-
-You can set the default size of the round robin database for all charts, using:
-
-```
-[global]
-      history = 600
-```
-
-The units for history is `[global].update every` seconds. So if `[global].update every = 6` and `[global].history = 600`, you will have an hour of data ( 6 x 600 = 3.600 ), which will store 600 points per dimension, one every 6 seconds.
-
-Check also [[Memory Requirements]] for directions on calculating the size of the round robin database.
-
----
-
-## 7. Disable gzip compression of responses
-
-Gzip compression of the web responses is using more CPU that the rest of netdata. You can lower the compression level or disable gzip compression completely. You can disable it, like this:
-
-```
-[web]
-	enable gzip compression = no
-```
-
-To lower the compression level, do this:
-
-```
-[web]
-	enable gzip compression = yes
-	gzip compression level = 1
-```
-
----
-
-Finally, if no web server is installed on your device, you can use port tcp/80 for netdata:
-
-```
-[global]
-	port = 80
-```
-
----
-
-## 8. Monitoring RPi temperature
-
-The python version of the sensors plugin uses `lm-sensors`. Unfortunately the temperature reading of RPi are not supported by `lm-sensors`.
-
-netdata also has a bash version of the sensors plugin that can read RPi temperatures. It is disabled by default to avoid the conflicts with the python version.
-
-To enable it, edit `/etc/netdata/charts.d.conf` and uncomment this line:
-
-```sh
-sensors=force
-```
-
-Then restart netdata. You will get this:

+# Charts, contexts, families
+
+Before configuring an alarm or writing a collector, it's important to understand how Netdata organizes collected metrics into charts. 
+
+## Charts
+
+Each chart that you see on the netdata dashboard contains one or more dimensions, one for each collected or calculated metric. 
+
+The chart name or chart id is what you see in parentheses at the top left corner of the chart you are interested in. For example, if you go to the system cpu chart: `http://your.netdata.ip:19999/#menu_system_submenu_cpu`, you will see at the top left of the chart the label "Total CPU utilization (system.cpu)". In this case, the chart name is `system.cpu`.  
+
+## Dimensions
+
+Most charts depict more than one dimensions. The dimensions of a chart are called "series" in some applications. You can see these dimensions on the right side of a chart, right under the date and time. For the system.cpu example we used, you will see the dimensions softirq, irq, user etc. Note that these are not always simple metrics (raw data). They could be calculated values (percentages, aggregates and more).
+
+## Families
+
+When you have several instances of a monitored hardware or software resource (e.g. network interfaces, mysql instances etc.), you need to be able to identify each one separately. Netdata uses "families" to identify such instances. For example, if I have the network interfaces `eth0` and `eth1`, `eth0` will be one family, and `eth1` will be another. 
+
+The reasoning behind calling these instances "families" is that different charts for the same instance can and many times are related (relatives, family, you get it). The family of a chart is usually the name of the netdata dashboard submenu that you see selected on the right navigation pane, when you are looking at a chart. For the example of the two network interfaces, you would see a submenu `eth0` and a submenu `eth1` under the "Network Interfaces" menu on the right navigation pane. 
+
+## Contexts
+
+A context is a grouping of identical charts, for each instance of the hardware or software monitored. For example, `health/health.d/net.conf` refers to four contexts: `net.drops`, `net.fifo`, `net.net`, `net.packets`. You can see the context of a chart if you hover over the date right above the dimensions of the chart.  The line that appears shows you two things: the collector that produces the chart and the chart context. 
+
+For example, let's take the `net.packets` context. You will see on the dashboard as many charts with context net.packets as you have network interfaces (families). These charts will be named `net_packets.[family]`. For the example of the two interfaces `eth0` and `eth1`, you will see charts named `net_packets.eth0` and `net_packets.eth1`. Both of these charts show the exact same dimensions, but for different instances of a network interface.

+# Getting Started
+
+These are your first steps **after** you have installed netdata. If you haven't installed it already, please check the [installation page](../packaging/installer).
+
+## Accessing the dashboard
+
+To access the netdata dashboard, navigate with your browser to:
+
+```
+http://your.server.ip:19999/
+```
+
+<details markdown="1"><summary>Click here, if it does not work.</summary>
+
+**Verify Netdata is running.**
+
+Open an ssh session to the server and execute `sudo ps -e | grep netdata`. It should respond with the PID of the netdata daemon. If it prints nothing, Netdata is not running. Check the [installation page](../packaging/installer) to install it.
+
+**Verify Netdata responds to HTTP requests.**
+
+Using the same ssh session, execute `curl -Ss http://localhost:19999`. It should dump on your screen the `index.html` page of the dashboard. If it does not, check the [installation page](../packaging/installer) to install it.
+
+**Verify Netdata receives the HTTP requests.**
+
+On the same ssh session, execute `tail -f /var/log/netdata/access.log` (if you installed the static 64bit package, use: `tail -f /opt/netdata/var/log/netdata/access.log`). This command will print on your screen all HTTP requests Netdata receives.
+
+Next, try to access the dashboard using your web browser, using the URL posted above. If nothing is printed on your terminal, the HTTP request is not routed to your Netdata.
+
+If you are not sure about your server IP, run this for a hint: `ip route get 8.8.8.8 | grep -oP " src [0-9\.]+ "`. It should print the IP of your server.
+
+If still Netdata does not receive the requests, something is blocking them. A firewall possibly. Please check your network.
+
+</details>&nbsp;<br/>
+
+When you install multiple Netdata servers, all your servers will appear at the `my-netdata` menu at the top left of the dashboard. For this to work, you have to manually access just once, the dashboard of each of your netdata servers.
+
+The `my-netdata` menu is more than just browser bookmarks. When switching Netdata servers from that menu, any settings of the current view are propagated to the other netdata server:
+
+- the current charts panning (drag the charts left or right),
+- the current charts zooming (`SHIFT` + mouse wheel over a chart),
+- the highlighted time-frame (`ALT` + select an area on a chart),
+- the scrolling position of the dashboard,
+- the theme you use,
+- etc.
+
+are all sent over to other netdata server, to allow you troubleshoot cross-server performance issues easily.
+
+## Starting and stopping Netdata
+
+Netdata installer integrates Netdata to your init / systemd environment.
+
+To start/stop Netdata, depending on your environment, you should use:
+
+- `systemctl start netdata` and `systemctl stop netdata`
+- `service netdata start` and `service netdata stop`
+- `/etc/init.d/netdata start` and `/etc/init.d/netdata stop`
+
+Once netdata is installed, the installer configures it to start at boot and stop at shutdown.
+
+For more information about using these commands, consult your system documentation.
+
+## Sizing Netdata
+
+The default installation of netdata is configured for a small round-robin database: just 1 hour of data. Depending on the memory your system has and the amount you can dedicate to Netdata, you should adapt this. On production systems with limited RAM, we suggest to set this to 3-4 hours. For best results you should set this to 24 or 48 hours.
+
+For every hour of data, Netdata needs about 25MB of RAM. If you can dedicate about 100MB of RAM to netdata, you should set its database size to 4 hours.
+
+To do this, edit `/etc/netdata/netdata.conf` (or `/opt/netdata/etc/netdata/netdata.conf`) and set:
+
+```
+[global]
+    history = SECONDS
+```
+
+Make sure the `history` line is not commented (comment lines start with `#`).
+
+1 hour is 3600 seconds, so the number you need to set is the result of `HOURS * 3600`.
+
+!!! danger
+    Be careful when you set this on production systems. If you set it too high, your system may run out of memory. By default, netdata is configured to be killed first when the system starves for memory, but better be careful to avoid issues.
+
+For more information about Netdata memory requirements, [check this page](../database).
+
+If your kernel supports KSM (most do), you can [enable KSM to half netdata memory requirement](../database#ksm).
+
+## Service discovery and auto-detection
+
+Netdata supports auto-detection of data collection sources. It auto-detects almost everything: database servers, web servers, dns server, etc.
+
+This auto-detection process happens **only once**, when netdata starts. To have Netdata re-discover data sources, you need to restart it. There are a few exceptions to this:
+
+- containers and VMs are auto-detected forever (when Netdata is running at the host).
+- many data sources are collected but are silenced by default, until there is useful information to collect (for example network interface dropped packet, will appear after a packet has been dropped).
+- services that are not optimal to collect on all systems, are disabled by default.
+- services we received feedback from users that caused issues when monitored, are also disabled by default (for example, `chrony` is disabled by default, because CentOS ships a version of it that uses 100% CPU when queried for statistics).
+
+Once a data collection source is detected, netdata will never quit trying to collect data from it, until Netdata is restarted. So, if you stop your web server, netdata will pick it up automatically when it is started again.
+
+Since Netdata is installed on all your systems (even inside containers), auto-detection is limited to `localhost`. This simplifies significantly the security model of a Netdata monitored infrastructure, since most applications allow `localhost` access  by default.
+
+A few well known data collection sources that commonly need to be configured are:
+
+- [systemd services utilization](../collectors/cgroups.plugin/#monitoring-systemd-services) are not exposed by default on most systems, so `systemd` has to be configured to expose those metrics.
+
+## Configuration quick start
+
+In netdata we have:
+
+- **internal** data collection plugins (running inside the netdata daemon)
+- **external** data collection plugins (independent processes, sending data to netdata over pipes)
+- modular plugin **orchestrators** (external plugins that have multiple data collection modules)
+
+You can enable and disable plugins (internal and external) via `netdata.conf` at the section `[plugins]`.
+
+All plugins have dedicated sections in `netdata.conf`, like `[plugin:XXX]` for overwriting their default data collection frequency and providing additional command line options to them.
+
+All external plugins have their own `.conf` file.
+
+All modular plugin orchestrators have a directory in `/etc/netdata` with a `.conf` file for each of their modules.
+
+It is complex. So, let's see the whole configuration tree for the `nginx` module of `python.d.plugin`:
+
+In `netdata.conf` at the `[plugins]` section, `python.d.plugin` can be enabled or disabled:
+
+```
+[plugins]
+    python.d = yes
+```
+
+In `netdata.conf` at the `[plugin:python.d]` section, we can provide additional command line options for `python.d.plugin` and overwite its data collection frequency:
+
+```
+[plugin:python.d]
+	update every = 1
+	command options = 
+```
+
+`python.d.plugin` has its own configuration file for enabling and disabling its modules (here you can disable `nginx` for example):
+
+```bash
+sudo /etc/netdata/edit-config python.d.conf
+```
+
+Then, `nginx` has its own configuration file for configuring its data collection jobs (most modules can collect data from multiple sources, so the `nginx` module can collect metrics from multiple, local or remote, `nginx` servers):
+
+```bash
+sudo /etc/netdata/edit-config python.d/nginx.conf
+```
+
+## Health monitoring and alarms
+
+Netdata ships hundreds of health monitoring alarms for detecting anomalies. These are optimized for production servers.
+
+Many users install netdata on workstations and are frustrated by the default alarms shipped with netdata. On these cases, we suggest to disable health monitoring.
+
+To disable it, edit `/etc/netdata/netdata.conf` (or `/opt/netdata/etc/netdata/netdata.conf` if you installed the static 64bit package) and set:
+
+```
+[health]
+    enabled = no
+```
+
+The above will disable health monitoring entirely.
+
+If you want to keep health monitoring enabled for the dashboard, but you want to disable email notifications, run this:
+
+```bash
+sudo /etc/netdata/edit-config health_alarm_notify.conf
+```
+
+and set `SEND_EMAIL="NO"`.
+
+(For static 64bit installations use `sudo /opt/netdata/etc/netdata/edit-config health_alarm_notify.conf`).
+
+## What is next?
+

 ## Public Disclosure Timing
 
 A public disclosure date is negotiated by the Netdata team and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to a few weeks. As a basic default, we expect report date to disclosure date to be on the order of 7 days. The Netdata team holds the final say when setting a disclosure date.

+# Performance
+
+netdata performance is affected by:
+
+**Data collection**
+- the number of charts for which data are collected
+- the number of plugins running
+- the technology of the plugins (i.e. BASH plugins are slower than binary plugins)
+- the frequency of data collection
+
+You can control all the above.
+
+**Web clients accessing the data**
+- the duration of the charts in the dashboard
+- the number of charts refreshes requested
+- the compression level of the web responses
+
+---
+
+## Netdata Daemon
+
+For most server systems, with a few hundred charts and a few thousand dimensions, the netdata daemon, without any web clients accessing it, should not use more than 1% of a single core.
+
+To prove netdata scalability, check issue [#1323](https://github.com/netdata/netdata/issues/1323#issuecomment-265501668) where netdata collects 95.000 metrics per second, with 12% CPU utilization of a single core!
+
+In embedded systems, if the netdata daemon is using a lot of CPU without any web clients accessing it, you should lower the data collection frequency. To set the data collection frequency, edit `/etc/netdata/netdata.conf` and set `update_every` to a higher number (this is the frequency in seconds data are collected for all charts: higher number of seconds = lower frequency, the default is 1 for per second data collection). You can also set this frequency per module or chart. Check the [daemon configuration](../daemon/config) for plugins and charts. For specific modules, the configuration needs to be changed in:
+- `python.d.conf` for [python](../collectors/python.d.plugin/#pythondplugin)
+- `node.d.conf` for [nodejs](../collectors/node.d.plugin/#nodedplugin)
+- `charts.d.conf` for [bash](../collectors/charts.d.plugin/#chartsdplugin)
+
+## Plugins
+
+If a plugin is using a lot of CPU, you should lower its update frequency, or if you wrote it, re-factor it to be more CPU efficient. Check [External Plugins](../collectors/plugins.d/) for more details on writing plugins.
+
+## CPU consumption when web clients are accessing dashboards
+
+Netdata is very efficient when servicing web clients. On most server platforms, netdata should be able to serve **1800 web client requests per second per core** for auto-refreshing charts.
+
+Normally, each user connected will request less than 10 chart refreshes per second (the page may have hundreds of charts, but only the visible are refreshed). So you can expect 180 users per CPU core accessing dashboards before having any delays.
+
+Netdata runs with the lowest possible process priority, so even if 1000 users are accessing dashboards, it should not influence your applications. CPU utilization will reach 100%, but your applications should get all the CPU they need.
+
+To lower the CPU utilization of netdata when clients are accessing the dashboard, set `web compression level = 1`, or disable web compression completely by setting `enable web responses gzip compression = no`. Both settings are in the `[web]` section.
+
+
+## Monitoring a heavy loaded system
+
+Netdata, while running, does not depend on disk I/O (apart its log files and `access.log` is written with buffering enabled and can be disabled). Some plugins that need disk may stop and show gaps during heavy system load, but the netdata daemon itself should be able to work and collect values from `/proc` and `/sys` and serve web clients accessing it.
+
+Keep in mind that netdata saves its database when it exits and loads it back when restarted. While it is running though, its DB is only stored in RAM and no I/O takes place for it.
+
+## Netdata process priority
+
+By default, netdata runs with the `idle` process scheduler, which assigns CPU resources to netdata, only when the system has such resources to spare.
+
+The following `netdata.conf` settings control this:
+
+```
+[global]
+    process scheduling policy = idle
+    process scheduling priority = 0
+    process nice level = 19
+```
+
+The policies supported by netdata are `idle` (the netdata default), `other` (also as `nice`), `batch`, `rr`, `fifo`. netdata also recognizes `keep` and `none` to keep the current settings without changing them.
+
+For `other`, `nice` and `batch`, the setting `process nice level = 19` is activated to configure the nice level of netdata. Nice gets values -20 (highest) to 19 (lowest).
+
+For `rr` and `fifo`, the setting `process scheduling priority = 0` is activated to configure the priority of the relative scheduling policy. Priority gets values 1 (lowest) to 99 (highest).
+
+For the details of each scheduler, see `man sched_setscheduler` and `man sched`.
+
+When netdata is running under systemd, it can only lower its priority (the default is `other` with `nice level = 0`). If you want to make netdata to get more CPU than that, you will need to set in `netdata.conf`:
+
+```
+[global]
+    process scheduling policy = keep
+```
+
+and edit `/etc/systemd/system/netdata.service` and add:
+
+```
+CPUSchedulingPolicy=other | batch | idle | fifo | rr
+CPUSchedulingPriority=99
+Nice=-10
+```
+
+## Running netdata in embedded devices
+
+Embedded devices usually have very limited CPU resources available, and in most cases, just a single core.
+
+> keep in mind that netdata on RPi 2 and 3 does not require any tuning. The default settings will be good. The following tunables apply only when running netdata on RPi 1 or other very weak IoT devices.
+
+We suggest to do the following:
+
+### 1. Disable External plugins
+
+External plugins can consume more system resources than the netdata server. Disable the ones you don't need. If you need them, increase their `update every` value (again in `/etc/netdata/netdata.conf`), so that they do not run that frequently.
+
+Edit `/etc/netdata/netdata.conf`, find the `[plugins]` section:
+
+```
+[plugins]
+	proc = yes
+
+	tc = no
+	idlejitter = no
+	cgroups = no
+	checks = no
+	apps = no
+	charts.d = no
+	node.d = no
+	python.d = no
+
+	plugins directory = /usr/libexec/netdata/plugins.d
+	enable running new plugins = no
+	check for new plugins every = 60
+```
+
+In detail:
+
+plugin|description
+:---:|:---------
+`proc`|the internal plugin used to monitor the system. Normally, you don't want to disable this. You can disable individual functions of it at the next section.
+`tc`|monitoring network interfaces QoS (tc classes)
+`idlejitter`|internal plugin (written in C) that attempts show if the systems starved for CPU. Disabling it will eliminate a thread.
+`cgroups`|monitoring linux containers. Most probably you are not going to need it. This will also eliminate another thread.
+`checks`|a debugging plugin, which is disabled by default.
+`apps`|a plugin that monitors system processes. It is very complex and heavy (consumes twice the CPU resources of the netdata daemon), so if you don't need to monitor the process tree, you can disable it.
+`charts.d`|BASH plugins (squid, nginx, mysql, etc). This is a heavy plugin, that consumes twice the CPU resources of the netdata daemon.
+`node.d`|node.js plugin, currently used for SNMP data collection and monitoring named (the name server).
+`python.d`|has many modules and can use over 20MB of memory.  
+
+For most IoT devices, you can disable all plugins except `proc`. For `proc` there is another section that controls which functions of it you need. Check the next section.
+
+---
+
+### 2. Disable internal plugins
+
+In this section you can select which modules of the `proc` plugin you need. All these are run in a single thread, one after another. Still, each one needs some RAM and consumes some CPU cycles. With all the modules enabled, the `proc` plugin adds ~9 MiB on top of the 5 MiB required by the netdata daemon. 
+
+```
+[plugin:proc]
+	# /proc/net/dev = yes                       # network interfaces
+	# /proc/diskstats = yes                     # disks
+...
+```
+
+Refer to the [proc.plugins documentation](../collectors/proc.plugin/) for the list and description of all the proc plugin modules.
+
+### 3. Lower internal plugin update frequency
+
+If netdata is still using a lot of CPU, lower its update frequency. Going from per second updates, to once every 2 seconds updates, will cut the CPU resources of all netdata programs **in half**, and you will still have very frequent updates.
+
+If the CPU of the embedded device is too weak, try setting even lower update frequency. Experiment with `update every = 5` or `update every = 10` (higher number = lower frequency) in `netdata.conf`, until you get acceptable results.
+
+Keep in mind this will also force dashboard chart refreshes to happen at the same rate. So increasing this number actually lowers data collection frequency but also lowers dashboard chart refreshes frequency.
+
+This is a dashboard on a device with `[global].update every = 5` (this device is a media player and is now playing a movie):		
+		
+![pi1](https://cloud.githubusercontent.com/assets/2662304/15338489/ca84baaa-1c88-11e6-9ab2-118208e11ce1.gif)
+
+### 4. Disable logs
+
+Normally, you will not need them. To disable them, set:
+
+```
+[global]
+	debug log = none
+	error log = none
+	access log = none
+```
+### 5. Set memory mode to RAM
+
+Setting the memory mode to `ram` will disable loading and saving the round robin database. This will not affect anything while running netdata, but it might be required if you have very limited storage available.
+
+```
+[global]
+	memory mode = ram
+```
+
+### 6. Use the single threaded web server
+
+Normally, netdata spawns a thread for each web client. This allows netdata to utilize all the available cores for servicing chart refreshes. You can however disable this feature and serve all charts one after another, using a single thread / core. This will might lower the CPU pressure on the embedded device. To enable the single threaded web server, edit `/etc/netdata/netdata.conf` and set `mode = single-threaded` in the `[web]` section.
+
+### 7. Lower memory requirements
+
+You can set the default size of the round robin database for all charts, using:
+
+```
+[global]
+      history = 600
+```
+
+The units for history is `[global].update every` seconds. So if `[global].update every = 6` and `[global].history = 600`, you will have an hour of data ( 6 x 600 = 3.600 ), which will store 600 points per dimension, one every 6 seconds.
+
+Check also [Database](../database) for directions on calculating the size of the round robin database.
+
+
+### 8. Disable gzip compression of responses
+
+Gzip compression of the web responses is using more CPU that the rest of netdata. You can lower the compression level or disable gzip compression completely. You can disable it, like this:
+
+```
+[web]
+	enable gzip compression = no
+```
+
+To lower the compression level, do this:
+
+```
+[web]
+	enable gzip compression = yes
+	gzip compression level = 1
+```
+
+Finally, if no web server is installed on your device, you can use port tcp/80 for netdata:
+
+```
+[web]
+	port = 80
+```

+# Anonymous Statistics
+
+From Netdata v1.12 and above, anonymous usage information is collected by default and send to Google Analytics. 
+The statistics calculated from this information will be 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.
+
+Information is sent to Netdata via two different channels:
+- Google Tag Manager is used when an agent's dashboard is accessed.
+- The script `anonymous-statistics.sh` is executed by the Netdata daemon, when Netdata starts, stops cleanly, or fails.
+
+Both methods are controlled via the same [opt-out mechanism](#opt-out)
+
+## Google tag manager
+
+Google tag manager (GTM) is the recommended way of collecting statistics for new implementations using GA. Unlike the older API, the logic of when to send information to GA and what information to send is controlled centrally.
+
+We have configured GTM to trigger the tag only when the variable `anonymous_statistics` is true. The value of this variable is controlled via the [opt-out mechanism](#opt-out).
+
+To ensure anonymity of the stored information, we have configured GTM's GA variable "Fields to set" as follows: 
+
+|Field Name|Value
+|---|---
+|page|netdata-dashboard
+|hostname|dashboard.my-netdata.io
+|anonymizeIp|true
+|title|netdata dashboard
+|campaignSource|{{machine_guid}}
+|campaignMedium|web
+|referrer|http://dashboard.my-netdata.io
+|Page URL|http://dashboard.my-netdata.io/netdata-dashboard
+|Page Hostname|http://dashboard.my-netdata.io
+|Page Path|/netdata-dashboard
+|location|http://dashboard.my-netdata.io
+
+In addition, the netdata-generated unique machine guid is sent to GA via a custom dimension.
+You can verify the effect of these settings by examining the GA `collect` request parameters.
+
+The only thing that's impossible for us to prevent from being **sent** is the URL in the "Referrer" Header of the browser request to GA. However, the settings above ensure that all **stored** URLs and host names are anonymized.
+
+## Anonymous Statistics Script
+
+Every time the daemon is started or stopped and every time a fatal condition is encountered, netdata uses the anonymous statistics script to collect system information and send 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 name, along with the source code function, source code filename and source code line number of the fatal error.
+ 
+To see exactly what and how is collected, you can review the script template `daemon/anonymous-statistics.sh.in`. The template is converted to a bash script called `anonymous-statistics.sh`, installed under the Netdata `plugins directory`, which is usually `/usr/libexec/netdata/plugins.d`. 
+
+## Opt-Out
+
+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`). The effect of creating the file is the following:
+- The daemon will never execute the anonymous statistics script
+- The anonymous statistics script will exit immediately if called via any other way (e.g. shell)
+- The Google Tag Manager Javascript snippet will remain in the page, but the linked tag will not be fired. The effect is that no data will ever be sent to GA.

+        -  One config file each, mainly to turn their modules on and off: `python.d.conf` for [python](../collectors/python.d.plugin/#pythondplugin), `node.d.conf` for [nodejs](../collectors/node.d.plugin/#nodedplugin) and `charts.d.conf` for [bash](../collectors/charts.d.plugin/#chartsdplugin) modules.
+        - One directory each, where the module-specific configuration files can be found.
+    - `stream.conf` is where you configure [streaming and replication](../streaming/#streaming-and-replication)
+    - `stats.d` is a directory under which you can add .conf files to add [synthetic charts](../collectors/statsd.plugin/#synthetic-statsd-charts).
+    - Individual collector plugin config files, such as `fping.conf` for the [fping plugin](../collectors/fping.plugin/) and `apps_groups.conf` for the [apps plugin](../collectors/apps.plugin/) 
+
+So there are many configuration files to control every aspect of Netdata's behavior. It can be overwhelming at first, but you won't have to deal with any of them, unless you have specific things you need to change. The following HOWTO will guide you on how to customize your netdata, based on what you want to do. 
+
+## How to
+
+### Change what I see
+
+##### Increase the metrics retention period
+
+Increase `history` in [netdata.conf [global]](../daemon/config/#global-section-options). Just ensure you understand [how much memory will be required](../database/)
+
+##### Reduce the data collection frequency
+
+Increase `update every` in [netdata.conf [global]](../daemon/config/#global-section-options). This is another way to increase your metrics retention period, but at a lower resolution than the default 1s.
+
+##### Modify how a chart is displayed
+
+In `netdata.conf` under `# Per chart configuration` you will find several [[CHART_NAME] sections](../daemon/config/#per-chart-configuration), where you can control all aspects of a specific chart. 
+
+##### Disable a collector
+
+Entire plugins can be turned off from the [netdata.conf [plugins]](../daemon/config/#plugins-section-options) section. To disable specific modules of a plugin orchestrator, you need to edit one of the following:
+- `python.d.conf` for [python](../collectors/python.d.plugin/#pythondplugin)
+- `node.d.conf` for [nodejs](../collectors/node.d.plugin/#nodedplugin)
+- `charts.d.conf` for [bash](../collectors/charts.d.plugin/#chartsdplugin)
+
+### Modify alarms and notifications
+
+##### Add a new alarm
+
+You can add a new alarm definition either by editing an existing stock alarm config file under `health.d` (e.g. `/etc/netdata/edit-config health.d/load.conf`), or by adding a new `.conf` file under `/etc/netdata/health.d`. The documentation on how to define an alarm is in [health monitoring](../health/#health-monitoring). It is suggested to look at some of the stock alarm definitions, so you can ensure you understand how the various options work.  
+
+##### Turn off all alarms and notifications
+
+Just set `enabled = no` in the [netdata.conf [health]](../daemon/config/#health-section-options) section
+
+##### Modify or disable a specific alarm
+
+The `health.d` directory that contains the alarm triggers for [health monitoring](../health/#health-monitoring). It has one .conf file per collector. You can easily find the .conf file you will need to modify, by looking for the "source" line on the table that appears on the right side of an alarm on the netdata gui. 
+
+For example, if you click on Alarms and go to the tab 'All', the default netdata installation will show you at the top the configured alarm for `10 min cpu usage` (it's the name of the badge). Looking at the table on the right side, you will see a row that says: `source	4@/usr/lib/netdata/conf.d/health.d/cpu.conf`. This way, you know that you will need to run `/etc/netdata/edit-config health.d/cpu.conf` and look for alarm at line 4 of the conf file. 
+
+As stated at the top of the .conf file, **you can disable an alarm notification by setting the 'to' line to: silent**.
+To modify how the alarm gets triggered, we suggest that you go through the guide on [health monitoring](../health/#health-monitoring).
+
+##### Receive notifications using my preferred method
+
+You only need to configure `health_alarm_notify.conf`. To learn how to do it, read first [alarm notifications](../health/notifications/#netdata-alarm-notifications) and then open the submenu `Supported Notifications` under `Alarm notifications` in the documentation to find the specific page on your prefered notification method. 
+
+### Make security-related customizations
+
+##### Change the netdata web server access lists
+
+You have several options under the [netdata.conf [web]](../web/server/#access-lists) section. 
+
+##### Stop sending info to registry.my-netdata.io
+
+You will need to configure the [registry] section in netdata.conf. First read the [registry documentation](../registry/). In it, are instructions on how to [run your own registry](../registry/#run-your-own-registry).
+
+##### Change the IP address/port netdata listens to
+
+The settings are under netdata.conf [web]. Look at the [web server documentation](../web/server/#binding-netdata-to-multiple-ports) for more info.
+
+### System resource usage
+
+##### Reduce the resources netdata uses
+
+The page on [netdata performance](Performance.md) has an excellent guide on how to reduce the netdata cpu/disk/RAM utilization to levels suitable even for the weakest [IoT devices](netdata-for-IoT.md).
+
+##### Change when netdata saves metrics to disk
+
+[netdata.conf [global]](../daemon/config/#global-section-options) : `memory mode`</details>
+
+##### Prevent netdata from getting immediately killed when my server runs out of memory
+
+You can change the netdata [OOM score](../daemon/#oom-score) in netdata.conf [global]. 
+
+### Other
+
+##### Move netdata directories
+
+The various directory paths are in [netdata.conf [global]](../daemon/config/#global-section-options).
+
+
+## How netdata configuration works
+
+The configuration files are `name = value` dictionaries 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. 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.
+
+## Netdata simple patterns
+
+Unix prefers regular expressions. But they are just too hard, too cryptic to use, write and understand.
+
+So, netdata supports [simple patterns](../libnetdata/simple_pattern/).

+
+netdata is a **very efficient** server performance monitoring solution. When running in server hardware, it can collect thousands of system and application metrics **per second** with just 1% CPU utilization of a single core. Its web server responds to most data requests in about **half a millisecond** making its web dashboards spontaneous, amazingly fast!
+
+netdata can also be a very efficient real-time monitoring solution for **IoT devices** (RPIs, routers, media players, wifi access points, industrial controllers and sensors of all kinds). Netdata will generally run everywhere a Linux kernel runs (and it is glibc and [musl-libc](https://www.musl-libc.org/) friendly).
+
+You can use it as both a data collection agent (where you pull data using its API), for embedding its charts on other web pages / consoles, but also for accessing it directly with your browser to view its dashboard.
+
+The netdata web API already provides **reduce** functions allowing it to report **average** and **max** for any timeframe. It can also respond in many formats including JSON, JSONP, CSV, HTML. Its API is also a **google charts** provider so it can directly be used by google sheets, google charts, google widgets.

+
+Although netdata has been significantly optimized to lower the CPU and RAM resources it consumes, the plethora of data collection plugins may be inappropriate for weak IoT devices. Please follow the guide on [running netdata in embedded devices](Performance.md)
+
+## Monitoring RPi temperature
+
+The python version of the sensors plugin uses `lm-sensors`. Unfortunately the temperature reading of RPi are not supported by `lm-sensors`.
+
+netdata also has a bash version of the sensors plugin that can read RPi temperatures. It is disabled by default to avoid the conflicts with the python version.
+
+To enable it, run `sudo edit-config charts.d.conf` and uncomment this line:
+
+```sh
+sensors=force
+```
+
+Then restart netdata. You will get this:

All netdata plugins (internal to the netdata daemon, and external ones written in any computer language), convert raw data collected into metrics, and only these metrics are stored in netdata databases, sent to upstream netdata servers, or archived to backend time-series databases.

+There are a few cases however that raw source data are only exposed to processes with escalated privileges. To support these cases, Netdata attempts to minimize and completely isolate the code that runs with escalated privileges.
 
-So, netdata **plugins**, even those running with escalated capabilities or privileges, perform a **hard coded data collection job**. They do not accept commands from netdata. The communication is strictly **unidirectional**: from the plugin towards the netdata daemon. The original application data collected by each plugin do not leave the process they are collected, are not saved and are not transferred to the netdata daemon. The communication from the plugins to the netdata daemon includes only chart metadata and processed metric values.
+So, Netdata **plugins**, even those running with escalated capabilities or privileges, perform a **hard coded data collection job**. They do not accept commands from Netdata. The communication is strictly **unidirectional**: from the plugin towards the Netdata daemon.

The raw data collected by the plugins of slave netdata servers are **never leaving the host they are collected**. The only data appearing on the wire are chart metadata and metric values. This communication is also **unidirectional**: slave netdata servers never accept commands from master netdata servers.

-Viewers will be able to get some information about the system netdata is running. This information is everything the dashboard provides. The dashboard includes a list of the services each system runs (the legends of the charts under the `Systemd Services` section),  the applications running (the legends of the charts under the `Applications` section), the disks of the system and their names, the user accounts of the system that are running processes (the `Users` and `User Groups` section of the dashboard), the network interfaces and their names (not the IPs) and detailed information about the performance of the system and its applications.

-Also, viewers could use netdata itself to stress your servers. Although the netdata daemon runs unprivileged, with the minimum process priority (scheduling priority `idle` - lower than nice 19) and adjusts its OutOfMemory (OOM) score to 1000 (so that it will be first to be killed by the kernel if the system starves for memory), some pressure can be applied on your systems if someone attempts a DDoS against netdata.

+**This is the best and the suggested way to protect Netdata**. Your systems **should** have a private administration and management LAN, so that all management tasks are performed without any possibility of them being exposed on the internet.
 
 For cloud based installations, if your cloud provider does not provide such a private LAN (or if you use multiple providers), you can create a virtual management and administration LAN with tools like `tincd` or `gvpe`. These tools create a mesh VPN allowing all servers to communicate securely and privately. Your administration stations join this mesh VPN to get access to management and administration tasks on all your cloud servers.
 
-For `gvpe` we have developed a [simple provisioning tool](https://github.com/netdata/netdata-demo-site/tree/master/gvpe) you may find handy (it includes statically compiled `gvpe` binaries for Linux and FreeBSD, and also a script to compile `gvpe` on your Mac).

+# Privacy Policy
+
+## 1. Preamble
+
+This Privacy Policy explains the collection, use, processing, transferring and disclosure of personal information by Netdata, Inc (“ND” or “Netdata”), a Delaware Corporation.
+
+This Privacy Policy is incorporated into and made part of the Netdata Master Terms of Use (“Master Terms”) located [here](terms-of-use.md).
+
+Unless otherwise noted on a particular website or service hosted by Netdata, this Privacy Policy applies to your use of all websites that Netdata operates. These include https://my-netdata.io and https://netdata.cloud, together with all other subdomains thereof, (collectively, the “Websites”). This Privacy Policy also applies to all products, information, and services provided through the Websites, including without limitation the ND agent, the ND registry, the ND hub and the ND cloud website (together with the Websites, the “Services”).
+
+In addition, supplemental Privacy Policy terms (“Supplemental Privacy Policy Terms”) may apply to a particular Service. All such Supplemental Privacy Policy Terms will be accessible for you to read either within, or through your use of, that particular Service.
+
+By accessing or using any of the Services, you are accepting and agreeing to the practices described in this Privacy Policy.
+
+## 2. 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 `my-netdata` menu. The menu lists the netdata servers you have visited. 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. The global 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.
+
+If sending this information is against your policies, you can [run your own registry](../registry/#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. The login name or email address of your profile may be used to attribute you in connection with any content you submit to any Service. 
+
+Anonymous Usage Statistics: From Netdata v1.12 and above, anonymous usage information is collected by default on certain events of the ND daemon and send to Google Analytics. 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 reate 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.

+# 1s granularity
+
+High resolution metrics are required to effectively monitor and troubleshoot systems and applications.
+
+## Why?
+
+- The world is going real-time. Today, customer experience is significantly affected by response time, so SLAs are tighter than ever before. It is just not practical to monitor a 2-second SLA with 10-second metrics.
+
+- IT goes virtual. Unlike real hardware, virtual environments are not linear, nor predictable. You cannot expect resources to be available when your applications need them. They will eventually be, but not exactly at the time they are needed. The latency of virtual environments is affected by many factors, most of which are outside our control, like: the maintenance policy of the hosting provider, the work load of third party virtual machines running on the same physical servers combined with the resource allocation and throttling policy among virtual machines, the provisioning system of the hosting provider, etc.
+
+## What do others do?
+
+So, why don't most monitoring platforms and monitoring SaaS providers offer high resolution metrics?
+
+They want to, but they can't, at least not massively.
+
+The reasons lie in their design decisions:
+
+1. Time-series databases (prometheus, graphite, opentsdb, influxdb, etc) centralize all the metrics. At scale, these databases can easily become the bottleneck of the whole infrastructure.
+
+2. SaaS providers base their business models on centralizing all the metrics. On top of the time-series database bottleneck they also have increased bandwidth costs. So, massively supporting high resolution metrics, destroys their business model.
+
+Of course, since a couple of decades the world has fixed this kind of scaling problems: instead of scaling up, scale out, horizontally. That is, instead of investing on bigger and bigger central components, decentralize the application so that it can scale by adding more smaller nodes to it.
+
+There have been many attempts to fix this problem for monitoring. But so far, all solutions required centralization of metrics, which can only scale up. So, although the problem is somehow managed, it is still the key problem of all monitoring platforms and one of the key reasons for increased monitoring costs.
+
+Another important factor is how resource efficient data collection can be when running per second. Most solutions fail to do it properly. The data collection agent is consuming significant system resources when running "per second", influencing the monitored systems and applications to a great degree.
+
+Finally, per second data collection is a lot harder. Busy virtual environments have [a constant latency of about 100ms, spread randomly to all data sources](https://docs.google.com/presentation/d/18C8bCTbtgKDWqPa57GXIjB2PbjjpjsUNkLtZEz6YK8s/edit#slide=id.g422e696d87_0_57). If data collection is not implemented properly, this latency introduces a random error of +/- 10%, which is quite significant for a monitoring system.
+
+So, the monitoring industry fails to massively provide high resolution metrics, mainly for 3 reasons:
+
+1. Centralization of metrics makes monitoring cost inefficient at that rate.
+2. Data collection needs optimization, otherwise it will significantly affect the monitored systems.
+3. Data collection is a lot harder, especially on busy virtual environments.
+
+## What does netdata do differently?
+
+Netdata decentralizes monitoring completely. Each Netdata node is autonomous. It collects metrics locally, it stores them locally, it runs checks against them to trigger alarms locally, and provides an API for the dashboards to visualize them. This allows Netdata to scale to infinity.
+
+Of course, Netdata can centralize metrics when needed. For example, it is not practical to keep metrics locally on ephemeral nodes. For these cases, Netdata streams the metrics in real-time, from the ephemeral nodes to one or more non-ephemeral nodes nearby. This centralization is again distributed. On a large infrastructure, there may be many centralization points.
+
+To eliminate the error introduced by data collection latencies on busy virtual environments, Netdata interpolates collected metrics. It does this using microsecond timings, per data source, offering measurements with an error rate of 0.0001%. When running [in debug mode, netdata calculates this error rate](https://github.com/netdata/netdata/blob/36199f449852f8077ea915a3a14a33fa2aff6d85/database/rrdset.c#L1070-L1099) for every point collected, ensuring that the database works with acceptable accuracy.
+
+Finally, Netdata is really fast. Optimization is a core product feature. On modern hardware, Netdata can collect metrics with a rate of above 1M metrics per second per core (this includes everything, parsing data sources, interpolating data, storing data in the time series database, etc). So, for a few thousands metrics per second per node, Netdata needs negligible CPU resources (just 1-2% of a single core). 
+
+Netdata has been designed to:
+- Solve the centralization problem of monitoring
+- Replace the console for performance troubleshooting.
+
+So, for Netdata 1s granularity is easy, the natural outcome...

+# Why Netdata
+
+> Any performance monitoring solution that does not go down to per second
+> collection and visualization of the data, is useless.
+> It will make you happy to have it, but it will not help you more than that. 
+
+Netdata is built around 4 principles:
+
+1. **[Per second data collection for all metrics.](1s-granularity.md)**
+
+    *It is impossible to monitor a 2 second SLA, with 10 second metrics.*
+
+2. **[Collect and visualize all the metrics from all possible sources.](unlimited-metrics.md)**
+
+    *To troubleshoot slowdowns, we need all the available metrics. The console should not provide more metrics.*
+
+3. **[Meaningful presentation, optimized for visual anomaly detection.](meaningful-presentation.md)**
+
+    *Metrics are a lot more than name-value pairs over time. The monitoring tool should know all the metrics. Users should not!*
+
+4. **[Immediate results, just install and use.](immediate-results.md)**
+
+    *Most of our infrastructure is standardized. There is no point to configure everything metric by metric.*
+
+Unlike other monitoring solutions that focus on metrics visualization,
+Netdata's helps us troubleshoot slowdowns without touching the console.
+
+So, everything is a bit different.

+# Immediate results
+
+Most of our infrastructure is based on standardized systems and applications. 
+ 
+It is a tremendous waste of time and effort, in a global scale, to require from all users to configure their infrastructure dashboards and alarms metric by metric.
+
+## Why?
+
+Most of the existing monitoring solutions, focus on providing a platform "for building your monitoring". So, they provide the tools to collect metrics, store them, visualize them, check them and query them. And we are all expected to go through this process.
+
+However, most of our infrastructure is standardized. We run well known Linux distributions, the same kernel, the same database, the same web server, etc.
+
+So, why can't we have a monitoring system that can be installed and instantly provide feature rich dashboards and alarms about everything we use? Is there any reason you would like to monitor your web server differently than me?
+
+What a waste of time and money! Hundreds of thousands of people doing the same thing over and over again, trying to understand what the metrics are, how to visualize them, how to configure alarms for them and how to query them when issues arise.
+
+## What do others do?
+
+Open-source solutions rely almost entirely on configuration. So, you have to go through endless metric-by-metric configuration yourself. The result will reflect your skills, your experience, your understanding.
+
+Monitoring SaaS providers offer a very basic set of pre-configured metrics, dashboards and alarms. They assume that you will configure the rest you may need. So, once more, the result will reflect your skills, your experience, your understanding.
+
+## What does netdata do?
+
+1. Metrics are auto-detected, so for 99% of the cases data collection works out of the box.
+2. Metrics are converted to human readable units, right after data collection, before storing them into the database.
+3. Metrics are structured, organized in charts, families and applications, so that they can be browsed.
+4. Dashboards are automatically generated, so all metrics are available for exploration immediately after installation.
+5. Dashboards are not just visualizing metrics; they are a tool, optimized for visual anomaly detection.
+6. Hundreds of pre-configured alarm templates are automatically attached to collected metrics.
+
+The result is that Netdata can be used immediately after installation!

+- Helps engineers understand and learn what the metrics are.
+- Does not require any configuration. Of course there are thousands of options to tweak, but the defaults are pretty good for most systems.
+- Does not introduce any query languages or any other technology to be learned. Of course some familiarity with the tool is required, but nothing too complicated.
+- Includes all the community expertise and experience for monitoring systems and applications.

+# Meaningful presentation
+
+Metrics are a lot more than name-value pairs over time. It is just not practical to require from all users to have a deep understanding of all metrics for monitoring their systems and applications.
+
+## Why?
+
+There is a plethora of metrics. And each of them has a context, a meaning, a way to be interpreted.
+
+Traditionally, monitoring solutions instruct engineers to collect only the metrics they understand. This is a good strategy as long as you have a clear understanding of what you need and you have the skills, the expertise and the experience to select them.
+
+For most people, this is an impossible task. It is just not practical to assume that any engineer will have a deep understanding of how the kernel works, how the networking stack works, how the system manages its memory, how it schedules processes, how web servers work, how databases work, etc.
+
+The result is that for most of the world, monitoring sucks. It is incomplete, inefficient, and in most of the cases only useful for providing an illusion that the infrastructure is being monitored. It is not! According to the [State of Monitoring 2017](http://start.bigpanda.io/state-of-monitoring-report-2017), only 11% of the companies are satisfied with their existing monitoring infrastructure, and on the average they use 6-7 monitoring tools.
+
+But even if all the metrics are collected, an even bigger challenge is revealed: What to do with them? How to use them?
+
+The existing monitoring solutions, assume the engineers will:
+ 
+- Design dashboards
+- Configure alarms
+- Use a query language to investigate issues
+
+However, all these have to be configured metric by metric.
+
+The monitoring industry believes there is this "IT Operations Hero", a person combining these abilities:
+
+1. Has a deep understanding of IT architectures and is a skillful SysAdmin.
+2. Is a superb Network Administrator (can even read and understand the Linux kernel networking stack).
+3. Is a exceptional database administrator.
+4. Is fluent in software engineering, capable of understanding the internal workings of applications.
+5. Masters Data Science, statistical algorithms and is fluent in writing advanced mathematical queries to reveal the meaning of metrics.
+
+Of course this person does not exist!
+
+## What do others do?
+
+Most solutions are based on a time-series database. A database that tracks name-value pairs, over time.
+
+Data collection blindly collects metrics and stores them into the database, dashboard editors query the database to visualize the metrics. They may also provide a query editor, that users can use to query the database by hand.
+
+Of course, it is just not practical to work that way when the database has 10,000 unique metrics. Most of them will be just noise, not because they are not useful, but because no one understands them!
+
+So, they collect very limited metrics. Basic dashboards can be created with these metrics, but for any issue that needs to be troubleshooted, the monitoring system is just not adequate. It cannot help. So, engineers are using the console to access the rest of the metrics and find the root cause.
+
+## What does netdata do?
+
+In netdata, the meaning of metrics is incorporated into the database:
+
+1. all metrics are converted and stored to human-friendly units. This is a data-collection process, not a visualization process. For example, cpu utilization in Netdata is stored as percentage, not as kernel ticks.
+
+2. all metrics are organized into human-friendly charts, sharing the same context and units (similar to what other monitoring solutions call `cardinality`). So, when Netdata developer collect metrics, they configure the correlation of the metrics right in data collection, which is stored in the database too.
+
+3. all charts are then organized in families, and chart families are organized in applications. These structures are responsible for providing the menu at the right side of Netdata dashboards for exploring the whole database.
+
+The result is a system that can be browsed by humans, even if the database has 100,000 unique metrics. It is pretty natural for everyone to browse them, understand their meaning and their scope.
+
+Of course, this process makes data collection significantly more time consuming. Netdata developers need to normalize and correlate and categorize every single metric Netdata collects.
+
+But it simplifies everything else. Data collection, metrics database and visualization are de-coupled, thus the query engine is simpler, and the visualization is straight forward.
+
+Netdata goes a step further, by enriching the dashboard with information that is useful for most people. So, to improve clarity and help users be more effective, Netdata includes right in the dashboard the community knowledge and expertise about the metrics. So, that Netdata users can focus on solving their infrastructure problem, not on the technicalities of data collection and visualization.

+# Unlimited metrics
+
+All metrics are important and all metrics should be available when you need them.  
+
+## Why?
+
+Collecting all the metrics breaks the first rule of every monitoring text book: "collect only the metrics you need", "collect only the metrics you understand".
+
+Unfortunately, this does not work! Filtering out most metrics is like reading a book by skipping most of its pages...
+
+For many people, monitoring is about:
+
+- Detecting outages
+- Capacity planning
+
+However, **slowdowns are 10 times more common** compared to outages (check slide 14 of [Online Performance is Business Performance ](https://www.slideshare.net/KenGodskind/alertsitetrac) reported by Trac Research/AlertSite). Designing a monitoring system targeting only outages and capacity planning solves just a tiny part of the operational problems we face. Check also [Downtime vs. Slowtime: Which Hurts More?](https://dzone.com/articles/downtime-vs-slowtime-which-hurts-more).
+
+To troubleshoot a slowdown, a lot more metrics are needed. Actually all the metrics are needed, since the real cause of a slowdown is most probably quite complex. If we knew the possible reasons, chances are we would have fixed them before they become a problem.
+
+## What do others do?
+
+Most monitoring solutions, when they are able to detect something, provide just a hint (e.g. "hey, there is a 20% drop in requests per second over the last minute") and they expect us to use the console for determining the root cause.
+
+Of course this introduces a lot more problems: how to troubleshoot a slowdown using the console, if the slowdown lifetime is just a few seconds, randomly spread throughout the day?
+
+You can't! You will spend your entire day on the console, waiting for the problem to happen again while you are logged in. A blame war starts: developers blame the systems, sysadmins blame the hosting provider, someone says it is a DNS problem, another one believes it is network related, etc. We have all experienced this, multiple times...
+
+So, why do monitoring solutions and SaaS providers filter out metrics?
+
+They can't do otherwise!
+
+1. Centralization of metrics depends on metrics filtering, to control monitoring costs. Time-series databases limit the number of metrics collected, because the number of metrics influences their performance significantly. They get congested at scale.
+2. It is a lot easier to provide an illusion of monitoring by using a few basic metrics.
+3. Troubleshooting slowdowns is the hardest IT problem to solve, so most solutions just avoid it.
+
+## What does netdata do?
+
+Netdata collects, stores and visualizes everything, every single metric exposed by systems and applications.
+
+Due to Netdata's distributed nature, the number of metrics collected does not have any noticeable effect on the performance or the cost of the monitoring infrastructure.
+
+Of course, since netdata is also about [meaningful presentation](meaningful-presentation.md), the number of metrics makes Netdata development slower. We, the Netdata developers, need to have a good understanding of the metrics before adding them into Netdata. We need to organize the metrics, add information related to them, configure alarms for them, so that you, the Netdata users, will have the best out-of-the-box experience and all the information required to kill the console for troubleshooting slowdowns.

+
+For some alarms we need compare two time-frames, to detect anomalies. For example, `health.d/httpcheck.conf` has an alarm template called `web_service_slow` that compares the average http call response time over the last 3 minutes, compared to the average over the last hour. It triggers a warning alarm when the average of the last 3 minutes is twice the average of the last hour. In such cases, it is easy to trigger the alarm, but difficult to tell when the alarm is cleared. As time passes, the newest window moves into the older, so the average response time of the last hour will keep increasing. Eventually, the comparison will find the averages in the two time-frames close enough to clear the alarm. However, the issue was not resolved, it's just a matter of the newer data "polluting" the old. For such alarms, it's a good idea to tell Netdata to not clear the notification, by using the `no-clear-notification` option.

+<details markdown="1"><summary>The variables below can be used in both chart alarms and context templates.</summary>
+Although the `alarm_variables` link shows you variables for a particular chart, the same variables can also be used in templates for charts belonging to the same [context](../docs/Charts.md#contexts). The reason is that all charts of a given contexts are essentially identical, with the only difference being the [family](../docs/Charts.md#families) that identifies a particular hardware or software instance. Charts and templates do not apply to specific families anyway, unless if you explicitly limit an alarm with the [alarm line `families`](#alarm-line-families).

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.

+If you need to dig even deeper, you can trace the execution with `bash -x`. Note that in test mode, alarm-notify.sh calls itself with many more arguments. So first do
+ ```sh
+ bash -x /usr/libexec/netdata/plugins.d/alarm-notify.sh test

+ Then look in the output for the alarm-notify.sh calls and run the one you want to trace with `bash -x`.

+(Prowl)[1] is a push notification service for iOS devices.  Netdata
+supprots delivering notifications to iOS devices through Prowl.
+
+Because of how Netdata integrates with Prowl, there is a hard limit of
+at most 1000 notifications per hour (starting from the first notification
+sent).  Any alerts beyond the first thousand in an hour will be dropped.
+
+Warning messages will be sent with the 'High' priority, critical messages
+will be sent with the 'Emergency' priority, and all other messages will
+be sent with the normal priority.  Opening the notification's associated
+URL will take you to the Netdata dashboard of the system that issued
+the alert, directly to the chart that it triggered on.
+
+## configuration
+
+To use this, you will need a Prowl API key, which can be rquested through
+the Prowl website after registering.
+
+Once you have an API key, simply specify that as a recipient for Prowl
+notifications.

 You need a working `logger` command for this to work.  This is the case on pretty much every Linux system in existence, and most BSD systems.
 
@@ -21,3 +21,5 @@ Targets are defined as follows:
 The `facility` and `level` are the standard syslog facility and level options, for more info on them see your local `logger` and `syslog` documentation.  By default, netdata will log to the `local6` facility, with a log level dependent on the type of message (`crit` for CRITICAL, `warning` for WARNING, and `info` for everything else).
 
 You can configure sending directly to remote log servers by specifying a host (and optionally a port).  However, this has a somewhat high overhead, so it is much preferred to use your local syslog daemon to handle the forwarding of messages to remote systems (pretty much all of them allow at least simple forwarding, and most of the really popular ones support complex queueing and routing of messages to remote log servers).

-# Uninstalling netdata
-
-## netdata was installed from source (or `kickstart.sh`)
-
-The script `netdata-installer.sh` generates another script called `netdata-uninstaller.sh`.
-
-To uninstall netdata, run:
-
-```
-cd /path/to/netdata.git
-./netdata-uninstaller.sh --force
-```
-
-The uninstaller will ask you to confirm all deletions.
-
-## netdata was installed with `kickstart-static64.sh` package
-
-Stop netdata with one of the following:
-
-- `service netdata stop` (non-systemd systems)
-- `systemctl stop netdata` (systemd systems)
-
-Disable running netdata at startup, with one of the following (based on your distro):
-
-- `rc-update del netdata`
-- `update-rc.d netdata disable`
-- `chkconfig netdata off`
-- `systemctl disable netdata`
-
-Delete the netdata files:
-
-1. `rm -rf /opt/netdata`
-2. `groupdel netdata`
-3. `userdel netdata`
-4. `rm /etc/logrotate.d/netdata`
-5. `rm /etc/systemd/system/netdata.service` or `rm /etc/init.d/netdata`, depending on the distro.

-# Updating netdata after its installation
-
-![image8](https://cloud.githubusercontent.com/assets/2662304/14253735/536f4580-fa95-11e5-9f7b-99112b31a5d7.gif)
-
-
-We suggest to keep your netdata updated. We are actively developing it and you should always update to the latest version.
-
-The update procedure depends on how you installed it:
-
-## You downloaded it from github using git
-
-### Manual update
-
-The installer `netdata-installer.sh` generates a `netdata-updater.sh` script in the directory you downloaded netdata. 
-You can use this script to update your netdata installation with the same options you used to install it in the first place.
-Just run it and it will download and install the latest version of netdata. The same script can be put in a cronjob to update your netdata at regular intervals.
-
-```sh
-# go to the git downloaded directory
-cd /path/to/git/downloaded/netdata
-
-# run the updater
-./netdata-updater.sh
-```
-
-_Netdata will be restarted with the new version._
-
-If you don't have this script (e.g. you deleted the directory where you downloaded netdata), just follow the **[[Installation]]** instructions again. The installer preserves your configuration. You can also update netdata to the latest version by hand, using this:
-
-```sh
-# go to the git downloaded directory
-cd /path/to/git/downloaded/netdata
-
-# download the latest version
-git pull
-
-# rebuild it, install it, run it
-./netdata-installer.sh
-```
-
-_Netdata will be restarted with the new version._
-
-Keep in mind, netdata may now have new features, or certain old features may now behave differently. So pay some attention to it after updating.
-
-### Auto-update
-
-_Please, consider the risks of running an auto-update. Something can always go wrong. Keep an eye on your installation, and run a manual update if something ever fails._
-
-You can call `netdata-updater.sh` from a cron-job. A successful update will not trigger an email from cron. 
-
-```sh
-# Edit your cron-jobs
-crontab -e
-
-# add a cron-job at the bottom. This one will update netdata every day at 6:00AM:
-# update netdata
-0 6 * * * /path/to/git/downloaded/netdata/netdata-updater.sh
-```
-
-## You downloaded a binary package
-
-If you installed it from a binary package, the best way is to **obtain a newer copy** from the source you got it in the first place.
-
-If a newer version of netdata is not available from the source you got it, we suggest to uninstall the version you have and follow the **[[Installation]]** instructions for installing a fresh version of netdata.

   You are attempting to install netdata as non-root, but you plan
   to install it in system paths.
-  
+
   Please set an installation prefix, like this:
-  
+
       $0 ${@} --install /tmp
-  
+
   or, run the installer as root:
-  
+
       sudo $0 ${@}
-  
+
   We suggest to install it as root, or certain data collectors will
   not be able to work. Netdata drops root privileges when running.
   So, if you plan to keep it, install it as root to get the full
   functionality.

-netdata is the fastest way to visualize metrics. It is a resource
-efficient, highly optimized system for collecting and visualizing any
-type of realtime timeseries data, from CPU usage, disk activity, SQL
-queries, API calls, web site visitors, etc.
-
-netdata tries to visualize the truth of now, in its greatest detail,
-so that you can get insights of what is happening now and what just
-happened, on your systems and applications.

-You can install the latest release of netdata, using your package manager in
+The best way to install Netdata is directly from source. Our **automatic installer** will install any required system packages and compile Netdata directly on your systems.

-   - Solus Linux (`sudo eopkg install netdata`)
-   - Ubuntu Linux >= 18.04 (`sudo apt install netdata`)
+!!! warning
+    You can find Netdata packages distributed by third parties. In many cases, these packages are either too old or broken. So, the suggested ways to install Netdata are the ones in this page.
+    **We are currently working to provide our binary packages for all Linux distros.** Stay tuned...
 
-Please note that the particular packages are not build by netdata.

+# Uninstalling netdata
+
+Our self-contained uninstaller is able to remove netdata installations created with shell installer. It doesn't need any other netdata repository files to be run. All it needs is an .environment file, which is created during installation (with shell installer) and put in ${NETDATA_USER_CONFIG_DIR}/.environment (by default /etc/netdata/.environment). That file contains some parameters which are passed to our installer and which are needed during uninstallation process. Mainly two parameters are needed:
+```
+NETDATA_PREFIX
+NETDATA_ADDED_TO_GROUPS
+```
+
+A workflow for uninstallation looks like this:
+
+1. Find your .environment file
+2. If you cannot find that file and would like to uninstall netdata, then create new file with following content:
+```
+NETDATA_PREFIX="<installation prefix>"   # put what you used as a parameter to shell installed `--install` flag. Otherwise it should be empty
+NETDATA_ADDED_TO_GROUPS="<additional groups>"  # Additional groups for a user running netdata process
+```
+3. Download [netdata-uninstaller.sh](https://github.com/netdata/netdata/blob/master/packaging/installer/netdata-uninstaller.sh) and run it as follows: `netdata-uninstaller.sh --yes --env <path_to_environment_file>`. The default `path_to_environment_file` is `/etc/netdata`, it's the location of the file `.environment` that is used by the uninstaller.
+
+
+Note: This uninstallation method assumes previous installation with netdata-installer.sh or kickstart script. Currently using it when netdata was installed by a package manager can work or cause unexpected results.

+
+
+We suggest to keep your netdata updated. We are actively developing it and you should always update to the latest version.
+
+The update procedure depends on how you installed it:
+
+## You downloaded it from github using git
+
+### Manual update to get the latest git commit
+
+netdata versions older than `v1.12.0-rc2-52` had a `netdata-updater.sh` script in the root directory of the source code, which has now been deprecated. The manual process that works for all versions to get the latest commit in git is to use the `netdata-installer.sh`. The installer preserves your custom configuration and updates the the information of the installation in the `.environment` file under the user configuration directory.
+
+```sh
+# go to the git downloaded directory
+cd /path/to/git/downloaded/netdata
+
+# update your local copy
+git pull
+
+# run the netdata installer
+sudo ./netdata-installer.sh
+```
+
+_Netdata will be restarted with the new version._
+
+Keep in mind, netdata may now have new features, or certain old features may now behave differently. So pay some attention to it after updating.
+
+### Manual update to get the latest nightly build
+
+The `kickstart.sh` one-liner will do a one-time update to the latest nightly build, if executed as follows:
+```
+bash <(curl -Ss https://my-netdata.io/kickstart.sh --no-updates)
+```
+
+### Auto-update
+
+_Please, consider the risks of running an auto-update. Something can always go wrong. Keep an eye on your installation, and run a manual update if something ever fails._
+
+Calling the `netdata-installer.sh` with the `--auto-update` or `-u` option will create the `netdata-updater` script under 
+either  `/etc/cron.daily/`, or `/etc/periodic/daily/`. Whenever the `netdata-updater` is executed, it checks if a newer nightly build is available and then handles the download, installation and netdata restart.  
+
+Note that after Jan 2019, the `kickstart.sh` one-liner `bash <(curl -Ss https://my-netdata.io/kickstart.sh)` calls the `netdata-installer.sh` with the auto-update option. So if you just run the one-liner without options once, your netdata will be kept auto-updated.
+
+
+## You downloaded a binary package
+
+If you installed it from a binary package, the best way is to **obtain a newer copy** from the source you got it in the first place.
+
+If a newer version of netdata is not available from the source you got it, we suggest to uninstall the version you have and follow the **[[Installation]]** instructions for installing a fresh version of netdata.

+# netdata static binary build
+
+To build the static binary 64-bit distribution package, run:
+
+```bash
+$ cd /path/to/netdata.git
+$ ./packaging/makeself/build-x86_64-static.sh
+```
+
+The program will:
+
+1. setup a new docker container with Alpine Linux
+2. install the required alpine packages (the build environment, needed libraries, etc)
+3. download and compile third party apps that are packaged with netdata (`bash`, `curl`, etc)
+4. compile netdata
+
+Once finished, a file named `netdata-vX.X.X-gGITHASH-x86_64-DATE-TIME.run` will be created in the current directory. This is the netdata binary package that can be run to install netdata on any other computer.
+
+---
+
+## building binaries with debug info
+
+To build netdata binaries with debugging / tracing information in them, use:
+
+```bash
+$ cd /path/to/netdata.git
+$ ./packaging/makeself/build-x86_64-static.sh debug
+```
+
+These binaries are not optimized (they are a bit slower), they have certain features disables (like log flood protection), other features enables (like `debug flags`) and are not stripped (the binary files are bigger, since they now include source code tracing information).
+
+#### debugging netdata binaries
+
+Once you have installed a binary package with debugging info, you will need to install `valgrind` and run this command to start netdata:
+
+```bash
+PATH="/opt/netdata/bin:${PATH}" valgrind --undef-value-errors=no /opt/netdata/bin/srv/netdata -D
+```
+
+The above command, will run netdata under `valgrind`. While netdata runs under `valgrind` it will be 10x slower and use a lot more memory.
+
+If netdata crashes, `valgrind` will print a stack trace of the issue. Open a github issue to let us know.
+
+To stop netdata while it runs under `valgrind`, press Control-C on the console.
+
+> If you omit the parameter `--undef-value-errors=no` to valgrind, you will get hundreds of errors about conditional jumps that depend on uninitialized values. This is normal. Valgrind has heuristics to prevent it from printing such errors for system libraries, but for the static netdata binary, all the required libraries are built into netdata. So, valgrind cannot appply its heuristics and prints them.

+# Health command API tester
+
+The directory `tests/health_cmdapi` contains the test script `health-cmdapi-test.sh` for the [health command API](../../web/api/health).
+
+The script can be executed with options to prepare the system for the tests, run them and restore the system to its previous state. 
+
+It depends on the management API being accessible and on the responses to the api/v1/alarms?all requests being functional.
+
+Run it with `tests/health_mgmtapi/health-cmdapi-test.sh -h` to see the options.

-## 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`

+# Health API Calls
+
+## Health Read API
+
+### Enabled Alarms
+
+NetData enables alarms on demand, i.e. when the chart they should be linked to starts collecting data. So, although many more alarms are configured, only the useful ones are enabled.
+
+To get the list of all enabled alarms:
+
+`http://your.netdata.ip:19999/api/v1/alarms?all`
+
+### Raised Alarms
+
+This API call will return the alarms currently in WARNING or CRITICAL state.
+
+`http://your.netdata.ip:19999/api/v1/alarms`
+
+### Event Log
+
+The size of the alarm log is configured in `netdata.conf`. There are 2 settings: the rotation of the alarm log file and the in memory size of the alarm log.
+
+```
+[health]
+	in memory max health log entries = 1000
+	rotate log every lines = 2000
+```
+
+The API call retrieves all entries of the alarm log:
+
+`http://your.netdata.ip:19999/api/v1/alarm_log`
+
+### Alarm Log Incremental Updates
+
+`http://your.netdata.ip:19999/api/v1/alarm_log?after=UNIQUEID`
+
+The above returns all the events in the alarm log that occurred after UNIQUEID (you poll it once without `after=`, remember the last UNIQUEID of the returned set, which you give back to get incrementally the next events).
+
+### Alarm badges
+
+The following will return an SVG badge of the alarm named `NAME`, attached to the chart named `CHART`.
+
+`http://your.netdata.ip:19999/api/v1/badge.svg?alarm=NAME&chart=CHART`
+
+## Health Management API
+
+Netdata v1.12 and beyond provides a command API to control health checks and notifications at runtime. The feature is especially useful for maintenance periods, during which you receive meaningless alarms.
+
+Specifically, the API allows you to:
+ - Disable health checks completely. Alarm conditions will not be evaluated at all and no entries will be added to the alarm log.
+ - Silence alarm notifications. Alarm conditions will be evaluated, the alarms will appear in the log and the netdata UI will show the alarms as active, but no notifications will be sent.
+ - Disable or Silence specific alarms that match selectors on alarm/template name, chart, context, host and family. 
+
+The API is available by default, but it is protected by an `api authorization token` that is stored in the file you will see in the following entry of `http://localhost:19999/netdata.conf`:
+
+```bash
+[registry]
+    # netdata management api key file = /var/lib/netdata/netdata.api.key
+```
+
+You can access the API via GET requests, by adding the bearer token to an `Authorization` http header, like this: 
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=RESET" -H "X-Auth-Token: Mytoken" 
+```
+
+The command `RESET` just returns netdata to the default operation, with all health checks and notifications enabled. 
+If you've configured and entered your token correclty, you should see the plain text response `All health checks and notifications are enabled`.
+
+### Disable or silence all alarms
+
+If all you need is temporarily disable all health checks, then you issue the following before your maintenance period starts:
+```
+curl "http://myserver/api/v1/manage/health?cmd=DISABLE ALL" -H "X-Auth-Token: Mytoken" 
+```
+The effect of disabling health checks is that the alarm criteria are not evaluated at all and nothing is written in the alarm log.
+If you want the health checks to be running but to not receive any notifications during your maintenance period, you can instead use this:
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=SILENCE ALL" -H "X-Auth-Token: Mytoken" 
+```
+
+Alarms may then still be raised and logged in netdata, so you'll be able to see them via the UI.  
+
+Regardless of the option you choose, at the end of your maintenance period you revert to the normal state via the RESET command.
+
+```
+ curl "http://myserver/api/v1/manage/health?cmd=RESET" -H "X-Auth-Token: Mytoken" 
+```
+
+### Disable or silence specific alarms
+
+If you do not wish to disable/silence all alarms, then the `DISABLE ALL` and `SILENCE ALL` commands can't be used. 
+Instead, the following commands expect that one or more alarm selectors will be added, so that only alarms that match the selectors are disabled or silenced.  
+- `DISABLE` : Set the mode to disable health checks. 
+- `SILENCE` : Set the mode to silence notifications. 
+
+You will normally put one of these commands in the same request with your first alarm selector, but it's possible to issue them separately as well. 
+You will get a warning in the response, if a selector was added without a SILENCE/DISABLE command, or vice versa. 
+
+Each request can specify a single alarm `selector`, with one or more `selection criteria`. 
+A single alarm will match a `selector` if all selection criteria match the alarm. 
+You can add as many selectors as you like.
+In essence, the rule is: IF (alarm matches all the criteria in selector1 OR all the criteria in selector2 OR ...) THEN apply the DISABLE or SILENCE command.
+
+To clear all selectors and reset the mode to default, use the `RESET` command.
+
+The following example silences notifications for all the alarms with context=load: 
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=SILENCE&context=load" -H "X-Auth-Token: Mytoken" 
+```
+
+#### Selection criteria 
+
+The `selection criteria` are key/value pairs, in the format `key : value`, where value is a netdata [simple pattern](../../../libnetdata/simple_pattern/). This means that you can create very powerful selectors (you will rarely need more than one or two). 
+
+The accepted keys for the `selection criteria` are the following:
+- `alarm`    : The expression provided will match both `alarm` and `template` names. 
+- `chart`    : Chart ids/names, as shown on the dashboard. These will match the `on` entry of a configured `alarm`.
+- `context`  : Chart context, as shown on the dashboard. These will match the `on` entry of a configured `template`.
+- `hosts`    : The hostnames that will need to match.
+- `families` : The alarm families.
+
+You can add any of the selection criteria you need on the request, to ensure that only the alarms you are interested in are matched and disabled/silenced. e.g. there is no reason to add `hosts: *`, if you want the criteria to be applied to alarms for all hosts. 
+
+Example 1: Disable all health checks for context = `random`
+
+```
+http://localhost/api/v1/manage/health?cmd=DISABLE&context=random
+```
+
+Example 2: Silence all alarms and templates with name starting with `out_of` on host `myhost`
+
+```
+http://localhost/api/v1/manage/health?cmd=SILENCE&alarm=out_of*&hosts=myhost
+```
+
+Example 2.2: Add one more selector, to also silence alarms for cpu1 and cpu2
+
+```
+http://localhost/api/v1/manage/health?families=cpu1 cpu2
+```
+
+### Responses
+
+- "Auth Error" : Token authentication failed
+- "All alarm notifications are silenced" : Successful response to cmd=SILENCE ALL
+- "All health checks are disabled" : Successful response to cmd=DISABLE ALL
+- "All health checks and notifications are enabled" : Successful response to cmd=RESET
+- "Health checks disabled for alarms matching the selectors" : Added to the response for a cmd=DISABLE
+- "Alarm notifications silenced for alarms matching the selectors" : Added to the response for a cmd=SILENCE
+- "Alarm selector added" : Added to the response when a new selector is added
+- "Invalid key. Ignoring it." : Wrong name of a parameter. Added to the response and ignored.
+- "WARNING: Added alarm selector to silence/disable alarms without a SILENCE or DISABLE command." : Added to the response if a selector is added without a selector-specific command.
+- "WARNING: SILENCE or DISABLE command is ineffective without defining any alarm selectors." : Added to the response if a selector-specific command is issued without a selector.

 The query engine is highly optimized for speed. Most of its modules implement "online"
 versions of the algorithms, requiring just one pass on the database values to produce
 the result.
+
+## Example
+
+When netdata is reducing metrics, it tries to return always the same boundaries. So, if we want 10s averages, it will always return points starting at a `unix timestamp % 10 = 0`.
+
+Let's see why this is needed, by looking at the error case.
+
+Assume we have 5 points:
+
+| time | value |
+| :-: | :-: |
+| 00:01 | 1 |
+| 00:02 | 2 |
+| 00:03 | 3 |
+| 00:04 | 4 |
+| 00:05 | 5 |
+
+At 00:04 you ask for 2 points for 4 seconds in the past. So `group = 2`. netdata would return:
+
+| point | time | value |
+| :-: | :-: | :-: |
+| 1 | 00:01 - 00:02 | 1.5 |
+| 2 | 00:03 - 00:04 | 3.5 |
+
+A second later the chart is to be refreshed, and makes again the same request at 00:05. These are the points that would have been returned:
+
+| point | time | value |
+| :-: | :-: | :-: |
+| 1 | 00:02 - 00:03 | 2.5 |
+| 2 | 00:04 - 00:05 | 4.5 |
+
+**Wait a moment!** The chart was shifted just one point and it changed value! Point 2 was 3.5 and when shifted to point 1 is 2.5! If you see this in a chart, it's a mess. The charts change shape constantly.
+
+For this reason, netdata always aligns the data it returns to the `group`.
+
+When you request `points=1`, netdata understands that you need 1 point for the whole database, so `group = 3600`. Then it tries to find the starting point which would be `timestamp % 3600 = 0` Within a database of 3600 seconds, there is one such point for sure. Then it tries to find the average of 3600 points. But, most probably it will not find 3600 of them (for just 1 out of 3600 seconds this query will return something).
+
+So, the proper way to query the database is to also set at least `after`. The following call will returns 1 point for the last complete 10-second duration (it starts at `timestamp % 10 = 0`):
+

+    <div class=container><h2>How it works</h2>
+        <div style="padding-bottom: 1em">
+            <p>
+                Netdata is a monitoring agent you install on all your systems:
+            <br/>
+                <b>physical servers</b>, <b>virtual servers</b>, <b>containers</b>, <b>IoT</b>.
+            </p>
+            <p>
+                Netdata is lightweight, designed to permanently run on all systems without disrupting their core function.
+                By default, it needs just 1% CPU of a single core, a few MB or RAM and no disk I/O at all.
+            </p>
+            <p>
+                Each Netdata is (by default) autonomous, taking care of all the following.
+                <br/>But all your Netdata are integrated into one large distributed application.
+            </p>
+        </div>
+        <div class=grid>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Collect</h3>
+                <p>
+                    Netdata automatically detects data collection sources on the host it runs.
+                    It comes with hundreds of plugins for collecting system and application metrics,
+                    including databases, web servers, and commonly used application servers.
+                    <br/> <br/>
+                    Netdata is also a high performance, distributed <b>statsd server</b>, allowing custom
+                    application metrics to be collected and visualized.
+                </p>
+            </div>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Check (alarms)</h3>
+                <p>
+                    Each Netdata spawns a thread that examines the metrics as they get collected,
+                    evaluates pre-configured alarm expressions and triggers alarm notifications.
+                    <br/> <br/>
+                    Netdata comes with hundreds of alarms to detect common system and application issues,
+                    that are automatically attached to the collected metrics,
+                    supporting dozens of alarm notification integrations.
+                </p>
+            </div>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Stream</h3>
+                <p>
+                    Each Netdata can stream its metrics, in real-time, to any other Netdata.
+                    Streaming allows Netdata to be used in ephemeral nodes and containers in auto-scaled environments,
+                    but it also allows building Netdata hierarchies for aggregating the metrics of multiple Netdata nodes.
+                </p>
+            </div>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Store</h3>
+                <p>
+                    Each Netdata has its own internal metrics database. This database is optimized
+                    for minimal memory footprint, and due to its lockless design allows one writer
+                    and multiple readers per metric, concurrently, contributing significantly to
+                    the performance of Netdata.
+                </p>
+            </div>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Archive</h3>
+                <p>
+                    Netdata can archive its metrics to time-series databases (prometheus, graphite, opentsdb, json document dbs, etc)
+                    so that Netdata can be integrated to existing monitoring tool-chains.
+                </p>
+            </div>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Visualize</h3>
+                <p>
+                    The best part of Netdata is its visualization. Low latency, speedy and snazzy.
+                    <br/> <br/>
+                    Netdata dashboards are optimized for visual anomaly detection, a powerful tool to troubleshoot
+                    performance issues.

-Netdata supports 3 implementations of its internal web server:

-- `static-threaded` is a web server with a fix (configured number of threads)
-- `single-threaded` is a simple web server running with a single thread
-- `multi-threaded` is a web server that spawns a thread for each client connection
-- `none` to disable the web server

 ### Binding netdata to multiple ports
 
-Netdata can bind to multiple IPs and ports. Up to 100 sockets can be used (you can increase it at compile time with `CFLAGS="-DMAX_LISTEN_FDS=200" ./netdata-installer.sh ...`).
+Netdata can bind to multiple IPs and ports, offering access to different services on each. Up to 100 sockets can be used (you can increase it at compile time with `CFLAGS="-DMAX_LISTEN_FDS=200" ./netdata-installer.sh ...`).
 
 The ports to bind are controlled via `[web].bind to`, like this:
 
 ```
 [web]
    default port = 19999
-   bind to = 127.0.0.1 10.1.1.1:19998 hostname:19997 [::]:19996 localhost:19995 *:http unix:/tmp/netdata.sock
+   bind to = 127.0.0.1=dashboard 10.1.1.1:19998=management|netdata.conf hostname:19997=badges [::]:19996=streaming localhost:19995=registry *:http=dashboard unix:/tmp/netdata.sock
 ```
 
 Using the above, netdata will bind to:
 
-- IPv4 127.0.0.1 at port 19999 (port was used from `default port`)
-- IPv4 10.1.1.1 at port 19998
-- All the IPs `hostname` resolves to (both IPv4 and IPv6 depending on the resolved IPs) at port 19997
-- All IPv6 IPs at port 19996
-- All the IPs `localhost` resolves to (both IPv4 and IPv6 depending the resolved IPs) at port 19996
-- All IPv4 and IPv6 IPs at port `http` as set in `/etc/services`
-- Unix domain socket `/tmp/netdata.sock`
+- IPv4 127.0.0.1 at port 19999 (port was used from `default port`). Only the UI (dashboard) and the read API will be accessible on this port. 
+- IPv4 10.1.1.1 at port 19998. The management API and netdata.conf will be accessible on this port.
+- All the IPs `hostname` resolves to (both IPv4 and IPv6 depending on the resolved IPs) at port 19997. Only badges will be accessible on this port.
+- All IPv6 IPs at port 19996. Only metric streaming requests from other netdata agents will be accepted on this port.
+- All the IPs `localhost` resolves to (both IPv4 and IPv6 depending the resolved IPs) at port 19996. This port will only accept registry API requests.
+- All IPv4 and IPv6 IPs at port `http` as set in `/etc/services`. Only the UI (dashboard) and the read API will be accessible on this port. 
+- Unix domain socket `/tmp/netdata.sock`. All requests are serviceable on this socket.
 
 The option `[web].default port` is used when an entries in `[web].bind to` do not specify a port.
 
+Note that the access permissions specified with the `=request type|request type|...` format are available from version 1.12 onwards. 
+As shown in the example above, these permissions are optional, with the default being to permit all request types on the specified port. 
+The request types are strings identical to the `allow X from` directives of the access lists, i.e. `dashboard`, `streaming`, `registry`, `netdata.conf`, `badges` and `management`. 
+The access lists themselves and the general setting `allow connections from` in the next section are applied regardless of the ports that are configured to provide these services. 
+The API requests are serviced as follows:
+- `dashboard` gives access to the UI, the read API and badges API calls.
+- `badges` gives access only to the badges API calls.
+- `management` gives access only to the management API calls.

+- `allow management from` checks the IPs to allow API management calls. Management via the API is currently supported for [health](../api/health/#health-management-api)

+web files owner | `netdata` | The user that owns the web static files. Netdata will refuse to serve a file that is not owned by this user, even if it has read access to that file. If the user given is not found, netdata will only serve files owned by user given in `run as user`. 
+web files group | `netdata` | If this is set, Netdata will check if the file is owned by this group and refuse to serve the file if it's not.
+disconnect idle clients after seconds | `60` | The time in seconds to disconnect web clients after being totally idle. 
+timeout for first request | `60` | How long to wait for a client to send a request before closing the socket. Prevents slow request attacks.
+accept a streaming request every seconds | `0` | Can be used to set a limit on how often a master Netdata server will accept streaming requests from the slaves in a [streaming and replication setup](../../streaming)

-# `multi-threaded` web server
-
-The `multi-threaded` web server spawns a thread for each connection it receives.
-
-Each thread uses non-blocking I/O so it can serve any number of web requests in parallel,
-though this is not supported by HTTP, so in practice each thread serves all the requests sequentially.
-
-Each thread respects the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.

-# `single-threaded` web server
-
-The `single-threaded` web server runs as a single thread inside netdata.
-It uses non-blocking I/O so it can serve any number of web requests in parallel.
-
-This web server respects the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.
