Nagios Support Forum

Hello Folks,

I need your suggestions on what could be the best possible way to monitor around 25K KVM based VMs using nagios XI as a solution.
I only need to monitor state of the VMs running on top of the KVM Hypervisor Servers. ( I guess there are plugins that make use of virsh list --all command to obtain a list of all VMs running on a host, and we can grep to obtain status like Running, stopped etc).

Now the question is what is best way to monitor 25K VMS (Only Status) . Is there any automated way i can achieve this . I dont want to add 25K monitors

Any ideas from you gurus will be highly highly appreciated.

Regards,
Fai

We don't have this in our environment to test, but I did find this plugin you could use as a base for a plugin to accomplish your goal.
