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

Hi Ernest Did you check vms/{vm:id}/disks/{disk:id}/statistics and vms/{vm:id}/nics/{nic:id}/statitics ? See more info here: http://www.ovirt.org/REST-Api#Where_can_I_find_network_and_IO_statiscs_for_v...
