There isn't anything built-in to Ceph to help with that. You could either increase the logging level for the OSDs and grep out "rbd_data." object accesses (assuming v2 image format), group by the image id, and figure out which image is being hammered. You could also create custom "iptables" LOG rules on the OSD nodes for each client-node to see which client client is sending/receiving the most data.
