Hello,

Is there a way in XI to monitor the load/CPU % of a particular process, command or service? For example,

Lets say I have four GVMs running on a KVM server. I want to monitor and graph the CPU or load on the host, of each of those virtual machines services. I know how to check for the service running, but I'm more interested in the ability to actually graph this information over time.

Here is the output of top. I'm interested in plotting, over time, PID 27742 as it uses considerable CPU.

top - 18:38:58 up 33 days, 8:57, 1 user, load average: 1.34, 2.16, 4.90
Tasks: 380 total, 1 running, 379 sleeping, 0 stopped, 0 zombie

Below is the output of ps.

So is there a plugin or some formatting to an already/exist function I could use to possibly do this?

Thanks!

I believe one of these may be what you are looking for
