I've been trying to complete the diagnostics command for libvirt, so far i think i can get the cpu usage (still need a sample time of 1 second), volume and network io. I still can't get the current memory and total memory. However, i believe the latter is a problem with libvirt, since i can't get the information through virsh as well.<br>

I'm looking for statistics about CPU, RAM usage etc. both from server itself (host) and Instances (Virtual Machines) inside openstack, because i'd like to write some piece of software which could analyze those data and for example, migrate one VM to another Host. Is it possible to do this right now in Openstack? Because all i can see on dashboard are stats about instance's type. I've seen in docs something about live-migration, but i can't find openstack's way to get informations about resources.<div>
