Nagios doesn't automagically run some commands from the remote node.
By your explanation, the check_munin.pl script is installed on the
remote server and munin is installed on the nagios server. You've
either explained the situation extremely poorly or completely
misunderstood how networking machines are allowed to talk to each
other in the unix world.
Either way, you need to rethink your mail, read it out loud a few
times and then fix what's broken with the mail or your thinking. If
that doesn't cause the bulb to go on in your head, I suggest you get
back here with more details about the setup. Use hostnames for the
nagios server and the server you're monitoring and explain what's
installed where when you mail again; Even if they're fake names,
they'll at least give us something to identify the different nodes
by so we can be sure what's done where.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
