Add more charts to netdata

Ilya Mashchenko edited this page Jul 8, 2018 · 93 revisions

netdata collects system metrics by itself. It has many internal plugins 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:

Check also Third Party Plugins for a list of plugins distributed by third parties.

configuring plugins

Most plugins 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 plugins are able to collect metrics, following this procedure:

# 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 configuration is kept at /etc/netdata. Each file should provide plenty of examples and documentation about each module and plugin.

This is a map of the all supported configuration options:

netdata plugin language configuration modules
configuration
apps.plugin C /etc/netdata/
apps_groups.conf
command line arguments, specified at /etc/netdata/netdata.conf, section [plugin:apps]
fping.plugin C with a BASH wrapper /etc/netdata/
fping.conf
N/A
freeipmi.plugin C N/A command line arguments specified at /etc/netdata/netdata.conf, section [plugin:freeipmi]
charts.d.plugin BASH /etc/netdata/

python.d.plugin python
