Subject: How to use check_cluster plugin
Message-ID: <2f71b4c6-2c90-49f5-af5a-3ed51c03929f@plusoptix.de>

Hello Plugin-Teams,

I did setup a monitoring nagios system for our cluster but i have some 
problems to find out the correct command line for the nagios plugin 
check_cluster.

I try to run it manually, afterwards I'll implement it in my nagios 
systems, so please help me with the command line approach.

I tried a lot of different approaches, this is what makes the most sense 
for me, but it still does not work:

/check_cluster -s -l "Host Cluster" -d "pri-vm-1,pri-vm-2" -w "0" -c "0"

So from my undestanding:

-s / I want to check services from clusters like VM's

-l? / I give the Check a Labelname

-d / I list different services i want to check

-w / I set warnings threshhold to 0 meaning 1 or more warnings i get a 
notification

-c? / Same as with warnings but for critical


What is working would be the following command line:

/check_cluster -s -l "Host Cluster" -d "0,0" -w "0" -c "0"

but I don't understand the benefit as i just tell the plugin -d "0,0". I 
am not really monitoring.


One last question would be if a stopped VM has status Critical or is it 
still Ok? With this information i could troubleshoot.

Please correct my first stated command line approach or tell me if I 
have to configure anything additional in the nrpe.cfg.


With kind regards,

Philip Schiller.
