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/$vm/blkio.throttle.io_serviced | grep
^253:.*Write | cut -f3 -d " " | paste -sd+ | bc
echo -n ":"
egrep -v "$IGNORED_REGEX"
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_service_bytes | grep
^253:.*Read | cut -f3 -d " " | paste -sd+ | bc
echo -n ":"
egrep -v "$IGNORED_REGEX"
/cgroup/blkio/libvirt/qemu/$vm/blkio.throttle.io_service_bytes | grep
^253:.*Write | cut -f3 -d " " | paste -sd+ | bc
echo -n ":"
cat /cgroup/cpuacct/libvirt/qemu/$vm/cpuacct.usage
) | tr -d '\n'
echo ""
done
