Thanks for response. In ‘ceph perf dump’ there is no statistics for read/write operations on specific RBD image, only for osd and total client operations. I need to get statistics on one specific RBD image, to get top used images. It is possible?

Best will be statistics like in /proc/diskstats in linux.
