how can I see cinder volume usage?
I install ceilometer and gnocchi and every thing work fine and I use https://docs.openstack.org/ceilometer...
and it gather whole volume size ,snapshot size, backup size
but I can not get volume usage forexample if I have 1TB volume and the vm use 100GB it should show 100GB not 1TB.
how can I see volume usage
this is my polling.yaml
