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 ?

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.

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

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