Hello,<br><br>Munin is a <strong style="font-weight: normal;">networked resource monitoring tool. Its installed on 0.5 machine as a client.<br>The script </strong>/usr/local/nagios/libexec/<a href="http://check_munin.pl/" target="_blank">check_munin.pl</a> is located on 0.1 machine and it should make the connection to 0.5 to fetch the information.<br>
<br>Well as far as i understand Use_node_name has to be set to YES. Thats atleast what all the howto-s on the web are telling.<br>Didn't sound very logical for me aswell, but example cases i checked had it always on YES.<br>

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

</div>Is the script /usr/local/nagios/libexec/<a href="http://check_munin.pl" target="_blank">check_munin.pl</a> located<br>
on 192.168.0.1 or on 192.168.0.5? It should reside on 192.168.0.1,<br>
and the script itself should connect to 192.168.0.1 with the<br>
correct parameters to fetch the data from that particular node.<br>

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