munin question

[Mipam]

Hi,

I installed munin-node from the ports.
There are some nice plugins, for example:

/usr/local/share/munin/pluginspostfix_mailqueue

I wish to display info which is generated by that scripts.
I assume it keeps stats about the mailq?
I added some machines with allow .... in the munin-node.conf file.
Right now i'm kind of stuck on how to display the stats gained by the
plugin. Any hints what i could do?
Bye,

Mipam.
