[libvirt-users] No way to obtain guest's cpu and mem usage?

Hi everybody, I'm using the PHP API to make a web interface interact with the virtual machines installed on some hypervisor. Everything is fine, but I would like to find a way to get the guest's cpu and mem usage, so that it should be possible to make some rrd graphs. I didn't find out anything and also it seems looking around that there is no way to obtain those data. What is strange for me is that programs like virt-top are showing exactly what I'm looking for. Can anyone help me to find out a way to retrieve those statistics? Another related question: do you think I can obtain the same data by using this: ps aux | egrep "[/]usr/libexec/qemu-kvm.*libvirt.*" | awk '{print $3"/"$4}' on the hypervisor? These are related to the kvm process, and the kvm process IS the virtual machine... Or not?
