DESCRIPTION
Munin's node is a daemon that Munin connects to fetch data. This data
is stored in .rrd-files, and later graphed and htmlified. It's designed
to let it be very easy to graph new datasources.
Munin-node is a small perlscript listening to port 4949 using
Net::Server. It reads all the plugins in /etc/munin/plugins/ on
startup. The node accepts the following commands:
- list [node]
- list available plugins for host. If no hostname is specified, list plugins on host running munin-node
- nodes
- List nodes that has plugins in this munin-node.
- config <plugin>
- output plugin configuration
- fetch <plugin>
- output plugin values
- version
- Print versionstring
- quit disconnect
- Plugins
- These plugins can be in you language of choice: bash, perl, python, C. The plugins can be run in two modes: with and without the "config"-parameter. When run with "config" as parameter, the plugin should output the configuration of the graph. When run without parameters, the plugin should output just values
