-# Configuration guide
-
-No configuration is required to run Netdata, but you will find plenty of options to tweak, so that you can adapt it to your particular needs.
-
-<details markdown="1"><summary>Configuration files are placed in `/etc/netdata`.</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>
-
-Under that directory you will see the following:
-
--   `netdata.conf` is [the main configuration file](../daemon/config/#daemon-configuration) 
--   `edit-config` is an sh script that you can use to easily and safely edit the configuration. Just run it to see its usage.
--   Other directories, initially empty, where your custom configurations for alarms and collector plugins/modules will be copied from the stock configuration, if and when you customize them using `edit-config`. 
--   `orig` is a symbolic link to the directory `/usr/lib/netdata/conf.d`, which contains the stock configurations for everything not included in `netdata.conf`:
-    -   `health_alarm_notify.conf` is where you configure how and to who Netdata will send [alarm notifications](../health/notifications/#netdata-alarm-notifications). 
-    -   `health.d` is the directory that contains the alarm triggers for [health monitoring](../health/#health-monitoring). It contains one .conf file per collector. 
-    -   The [modular plugin orchestrators](../collectors/plugins.d/#external-plugins-overview) have:
-        -   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
-
-### Persist my configuration
-
-In <http://localhost:19999/netdata.conf>, you will see the following two parameters:
-
-```bash
-	# config directory = /etc/netdata
-	# stock config directory = /usr/lib/netdata/conf.d
-```
-
-To persist your configurations, don't edit the files under the `stock config directory` directly. Use the `sudo [config directory]/edit-config` command, or copy the stock config file to its proper place under the `config directory` and edit it there. 
-
-### 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)
-
-##### Show charts with zero metrics
-
-By default, Netdata will enable monitoring metrics for disks, memory, and network only when they are not zero. If they are constantly zero they are ignored. Metrics that will start having values, after Netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though). Use `yes` instead of `auto` in plugin configuration sections to enable these charts permanently. You can also set the `enable zero metrics` option to `yes` in the `[global]` section which enables charts with zero metrics for all internal Netdata plugins.
-
-### 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`
-
-##### 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/).
