+# Add more charts to netdata
+
+netdata collects system metrics by itself. 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
+- **[Print Servers](#print-servers)**, like CUPS
+- **[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

+
+## 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
+	# cups = 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:
+
