libvirt users - Jun 2015 - CPU Usage and Memory Usage for VM and Host

Hi All,

I would like to know if there is a way to fetch the "CPU Usage and Memory
Usage for VM "  and CPU Usage and Memory Usage for a Host in the KVM
environment using libvirt java sdk .
I am using libvirt-0.5.1.jar.
This is the maximum Information I could fetch using the libvirt java API.:

I tried looking into the libvirt java sdk but did not find any methods to fetch
the exact  CPU Usage percentage and Memory Usage percentage for a VM and Host.

Can you please provide me with the java example if possible.

Thanks,
