Hi,
Is it possible to get the CPU usage of a guest through a virsh
command? I have tried almost all the commands (vcpuinfo, cpu-stats,
etc.) that gets the details of a guest cpu, but it only returns the cpu
time. Is there any command that returns the cpu usage (just like the
graph that virt-manager displays) of a guest? Or do I have to create a
program using libvirt API? Thanks in advance.
As I replied in your previous e-mail, libvirt doesn't expose this kind
of information. It's the best if client computes the value it needs from
the information libvirt provides.
Having said that, virt-top[1] may serve as good example, although it's
written in OCaml, not C.
