Hi, I am using nagios plugin check_xen (<a href="http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2272.html;d=1">http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2272.html;d=1</a>) for monitoring domU, My requirement is I am associating two names to domU. For example vhost-0072-01 and MiniStats,so is there a way i can assosciate two names to a domU using check_xen Nagios Plugin.Here MiniStats is a functional name Explained below in detail For example I have dom0 as host0072 and on these dom0 I have 2 domU viz vhost-0072-01 and vhost-0072-02. In our DNS setup we have something called as Functional names associated with this domU. say For example vhost-0072-01 -> MiniStats vhost-0072-02 -> MiniWeb so MiniStats is Functional name to vhost-0072-01 and MiniWeb is Functional name to vhost-0072-02 Is there a way i can specify both vhost-0072-01 and MiniStats in check_xen plugin option, so that its easier for us to recognize that if MiniStats go down that means the vhost-0072-01 has gone down Right now I am using the below command in the nrpe.cfg file in nagios on the client side command[check_vhost1]=/usr/nagios/libexec/check_xen domU MiniStats So in this case its difficult to remember which domU its associated with if MiniStats go down. So is this possible or do you have any other option, Please let me know command[check_vhost1]=/usr/nagios/libexec/check_xen domU MiniStats(vhost-0072-01) The above command wont work I believe so. I have not tried. Please let me know if you need any additional information from me Thanks and Regards Kaushal
