 Hi All,
 
 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 ?
 
 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.
 
 I run something like this on each hypervisor periodically via mrtg:
 
 vms=`find /cgroup/blkio/libvirt/qemu/ -maxdepth 1 -mindepth 1 -type d -printf
 %f\n`
 IGNORED_REGEX=ignore
 for vm in $vms
 do
 (
 echo -n $HOST:$vm:
 egrep -v $IGNORED_REGEX
 /cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_serviced | grep ^253:.*Read
 | cut -f3 -d   | paste -sd+ | bc
 echo -n :
 egrep -v $IGNORED_REGEX
 /cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_serviced | grep

Hi Ernest
Did you check vms/{vm:id}/disks/{disk:id}/statistics and 
vms/{vm:id}/nics/{nic:id}/statitics ?

See more info here:

Did you try with vms/{vm:id}/nics/{nic:id}/statistics? Note that
currently we have the following statistics available there:

  data.current.rx Receive data rate
  data.current.tx Transmit data rate
  errors.total.rx Total transmit errors
  errors.total.tx Total transmit errors

I guess that this isn't what you are looking for, but we don't have
anything else at the moment.

For disk IO you should take a look at
vms/{vm:id}/disks/{disk:id}/statistics. The collection of statistics
available there is the following:

  data.current.read Read data rate
  data.current.write Write data rate
  disk.read.latency Read latency
  disk.write.latency Write latency
  disk.flush.latency Flush latency

Does this cover your needs? If it doesn't I'd suggest that you open a
RFE to request adding additional statistics. Meanwhile you will have to
use other mechanisms to find the statistics that you need.
