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.
This is the third article in a series on munin. This installment covers the use of the munin-node-configure command to view and enable munin's default plug-ins.
