Munin plugins for single node multi host graphs. These make use of serafena, by signalling to receiving hosts execution of service status. Receiving hosts are gathered in a group by the name "munin", so they can all be addressed in a single command: signal @munin status. As the output has been parse-friendlyly formatted, the netwide plugin becomes rather simple.
An example of produced output is shown here
There are two different versions of the same plugins. The set in munin-node is executed from regular munin-node, as plugins. You may want to use this version if the machine is running as munin node already, of if you're planning to set it up as one.
The version in standalone is a bash written minimal munin node together with all those plugins in a single file. This minimal node is invoked from xinetd, the xinetd configuration file has been provided.
Either version serves lanwide munin information, which is collected by a single machine, by sending the status request to the monitored hosts through serafena, None of the hosts need to be regular munin nodes, when using standalone version. For the plugin set for regular munin node, only the host queried by the munin server needs to be a regular munin node.
