It has many [internal plugins](../collectors) for collecting most of the metrics presented by default when it starts, collecting data from `/proc`, `/sys` and other Linux kernel sources. + +To collect non-system metrics, netdata supports a plugin architecture. The following are the currently available external plugins: + +- **[Web Servers](#web-servers)**, such as apache, nginx, nginx_plus, tomcat, litespeed +- **[Web Logs](#web-log-parsers)**, such as apache, nginx, lighttpd, gunicorn, squid access logs, apache cache.log +- **[Load Balancers](#load-balancers)**, like haproxy +- **[Message Brokers](#message-brokers)**, like rabbitmq, beanstalkd +- **[Database Servers](#database-servers)**, such as mysql, mariadb, postgres, couchdb, mongodb, rethinkdb +- **[Social Sharing Servers](#social-sharing-servers)**, like retroshare +- **[Proxy Servers](#proxy-servers)**, like squid +- **[HTTP accelerators](#http-accelerators)**, like varnish cache +- **[Search engines](#search-engines)**, like elasticsearch +- **[Name Servers](#name-servers)** (DNS), like bind, nsd, powerdns, dnsdist +- **[DHCP Servers](#dhcp-servers)**, like ISC DHCP +- **[UPS](#ups)**, such as APC UPS, NUT +- **[RAID](#raid)**, such as linux software raid (mdadm), MegaRAID +- **[Mail Servers](#mail-servers)**, like postfix, exim, dovecot +- **[File Servers](#file-servers)**, like samba, NFS, ftp, sftp, WebDAV +- **[System](#system)**, for processes and other system metrics +- **[Sensors](#sensors)**, like temperature, fans speed, voltage, humidity, HDD/SSD S.M.A.R.T attributes +- **[Network](#network)**, such as SNMP devices, `fping`, access points, dns_query_time +- **[Time Servers](#time-servers)**, like chrony +- **[Security](#security)**, like FreeRADIUS, OpenVPN, Fail2ban +- **[Telephony Servers](#telephony-servers)**, like openSIPS +- **[Go applications](#go-applications)** +- **[Household appliances](#household-appliances)**, like SMA WebBox (solar power), Fronius Symo solar power, Stiebel Eltron heating +- **[Java Processes](#java-processes)**, via JMX or Spring Boot Actuator +- **[Provisioning Systems](#provisioning-systems)**, like Puppet +- **[Game Servers](#game-servers)**, like SpigotMC +- **[Distributed Computing Clients](#distributed-computing-clients)**, like BOINC +- **[Skeleton Plugins](#skeleton-plugins)**, for writing your own data collectors + +Check also [Third Party Plugins](Third-Party-Plugins.md) for a list of plugins distributed by third parties. + +## configuring plugins + +netdata comes with **internal** and **external** plugins: + +1. The **internal** ones are written in `C` and run as threads within the netdata daemon. +2. The **external** ones can be written in any computer language. The netdata daemon spawns these as processes (shown with `ps fax`) and reads their metrics using pipes (so the `stdout` of external plugins is connected to netdata for metrics collection and the `stderr` of external plugins is connected to `/var/log/netdata/error.log`). + +To make it easier to develop plugins, and minimize the number of threads and processes running, netdata supports **plugin orchestrators**, each of them supporting one or more data collection **modules**. Currently we ship plugin orchestrators for 4 languages: `C`, `python`, `node.js` and `bash` and 2 more are under development (`go` and `java`). + +#### enabling and disabling plugins + +To control which plugins netdata run, edit `netdata.conf` and check the `[plugins]` section. It looks like this: + +``` +[plugins] + # enable running new plugins = yes + # check for new plugins every = 60 + # proc = yes + # diskspace = yes + # cgroups = yes + # tc = yes + # nfacct = yes + # idlejitter = yes + # freeipmi = yes + # node.d = yes + # python.d = yes + # fping = yes + # charts.d = yes + # apps = yes +``` + +The default for all plugins is the option `enable running new plugins`. So, setting this to `no` will disable all the plugins, except the ones specifically enabled. + +#### enabling and disabling modules + +Each of the **plugins** may support one or more data collection **modules**. To control which of its modules run, you have to consult the configuration of the **plugin** (see table below). + +#### modules configuration + +Most **modules** come with **auto-detection**, configured to work out-of-the-box on popular operating systems with the default settings. + +However, there are cases that auto-detection fails. Usually the reason is that the applications to be monitored do not allow netdata to connect. In most of the cases, allowing the user `netdata` from `localhost` to connect and collect metrics, will automatically enable data collection for the application in question (it will require a netdata restart). + +You can verify netdata **external plugins and their modules** are able to collect metrics, following this procedure: + +```sh +# become user netdata +sudo su -s /bin/bash netdata + +# execute the plugin in debug mode, for a specific module. +# example for the python plugin, mysql module: +/usr/libexec/netdata/plugins.d/python.d.plugin 1 debug trace mysql +``` + +Similarly, you can use `charts.d.plugin` for BASH plugins and `node.d.plugin` for node.js plugins. +Other plugins (like `apps.plugin`, `freeipmi.plugin`, `fping.plugin`) use the native netdata plugin API and can be run directly. + +If you need to configure a netdata plugin or module, all user supplied configuration is kept at `/etc/netdata` while the stock versions of all files is at `/usr/lib/netdata/conf.d`. +To copy a stock file and edit it, run `/etc/netdata/edit-config`. Running this command without an argument, will list the available stock files. + +Each file should provide plenty of examples and documentation about each module and plugin. + +This is a map of the all supported configuration options: + +#### map of configuration files + +plugin | language | plugin<br/>configuration | modules<br/>configuration | +---:|:---:|:---:|:---| +`apps.plugin`<br/>(external plugin for monitoring the process tree on Linux and FreeBSD)|`C`|`netdata.conf` section `[plugin:apps]`|Custom configuration for the processes to be monitored at `apps_groups.conf` +`freebsd.plugin`<br/>(internal plugin for monitoring FreeBSD system resources)|`C`|`netdata.conf` section `[plugin:freebsd]`|one section for each module `[plugin:freebsd:MODULE]`.
