Dear Ceph folks,

I have a Luminous ceph cluster serving rbd block devices for an openstack cluster. My team leader would like me to show the performance view of these rbd block devices, including IOPS and BW, to get to know which rbd consumes most. I heard that Nautilous can do this , but how to get those statistics for Luminous version?

Any help would be highly appreciated,

thanks in advance,

Samuel
