His dilemma sounded like he has access to the cluster, but not any of the clients where the RBDs are used or even the hypervisors in charge of those.

Is there a way I could get a performance stats for rbd images? I'm looking for iops and throughput.
This issue we are dealing with is that there was a sudden jump in throughput and I want to be able to find out with rbd volume might be causing it. I just manage the ceph cluster, not the openstack hypervisors. I'm hoping I can figure out the offending volume with the tool set I have.
Thanks,
