I assume Munin is some system where "plugin" has a different
meaning than it does in Nagios. Bear in mind that I have no
idea what munin is or what it does.

Is the script /usr/local/nagios/libexec/check_munin.pl located
on 192.168.0.1 or on 192.168.0.5? It should reside on 192.168.0.1,
and the script itself should connect to 192.168.0.1 with the
correct parameters to fetch the data from that particular node.

You say "use_node_name" in the munin.conf on 192.168.0.1 but
still connect via ip address. I don't know anything about
Munin, but that seems like one possible source of error if
check_munin.pl expects you to pass it a munin node-name.

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.
