[Nagiosplug-help] Xen VM Monitor plugin problem

[Hydropone]

Hi all,

I just found this cool plugin :
http://www.novell.com/communities/node/2640/xen-virtual-machine-monitor-plugin-nagios


to monitor VM on a Xen Host.

I followed the readme (and add user "nagios" to /etc/sudoers) ...

The plugin seems to work correctly on the Xen Host :

[root at host plugins]# su nagios
sh-3.1$ /usr/lib64/nagios/plugins/check_xen -w 0 -c 0
OK: Xen Hypervisor "host" is running Xen VMs: testvm

But on the nagios server, it report a wrong result :

root at nagios~ #/usr/lib/nagios/plugins/check_nrpe -H host -c check_xen
Critical Xen VMs Usage - Total NB: 0 - detected VMs:

What did i miss ?

Thanks for your help.
