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

        # /etc/munin/plugins/load config
        host_name 
        graph_title Load average
        graph_args --base 1000 -l 0
        graph_vlabel load
        load.label load
        load.draw LINE2
        load.warning 10
        load.critical 120
