Enabling munin node plug-ins Overview

Munin uses plug-ins to determine what data is gathered and reported. It includes several plug-ins for the types of data most people would be interested in, but not all of those plug-ins are enabled on a fresh installation.

What are plug-ins?

When a munin node gathers data about a slice so it can be graphed, the node reads instructions from files called "plug-ins" to determine what information to collect. Several plug-ins are installed with munin but not all of them are used by default. Fortunately a munin node installation includes a command that lets you see what plug-ins are active and can help you decide which others to enable.
