Nagios Support Forum

Hello Guys,

I am not new to Nagios but I am new to configuring checks. I found a plugin for monitoring KVM and got it into the Proper place, However I keep getting this -> Host Health CRITICAL 2016-09-03 11:39:12 0d 21h 41m 59s 4/4 (null). Now i am using Nconf, I know it's no longer developed and appears to not be supported how ever it still works pretty good. Any whoooo I have a check_kvm

From the Nagios server i run this command and it works fine:
/usr/lib/nagios/plugins/check_nrpe -H 192.168.1.2 -c check_kvm
hosts:1 OK:1 WARN:0 CRIT:0 - cfdns02:running

But when I go into the GUI I see this (noted above) -> Host Health CRITICAL 2016-09-03 11:39:12 0d 21h 41m 59s 4/4 (null).

This is where it is located -> https://exchange.nagios.org/directory/P ... vm/details

So I am not sure what I am doing wrong, any help would be appreciated,
Thanks,
Michael

This may be nconf related to be honest which is out of our scope for support, but if it's just a host / service definition it shouldn't be too difficult.

Please post the related host / service definition for us to look at.

I believe i see the issue now I have to figure out how to define it in the services part of the file.

Thanks I think you got me in the right direction.

You got it, I don't see anything defined for the check_kvm plugin, give that a shot and let us know if you have any further questions.
