<br>
Is there any api methods to get the real time network usages and
IO usages os of each vm ? I tried it by using
api/vms/$id/statistics but its not getting the network and IO
usages. Is it possible to get these details using the api calls
?<br>

I had to make my own based on the hosts cgroups info. I feed the
data to mrtg to plot cpu and IO graphs. No network though.<br>
<br>
I run something like this on each hypervisor periodically via mrtg:<br>

<tt><tt>vms=`find /cgroup/blkio/libvirt/qemu/ -maxdepth 1 -mindepth
1 -type d -printf "%f\n"`<br>
