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?
Regards
Mateusz

Yes, you just need to enable the "admin socket" in your ceph.conf and then use "ceph --admin-daemon /path/to/image/admin/socket.asok perf dump".

Hi,
It is possible to get statistics of issued reads/writes to specific RBD image? Best will be statistics like in /proc/diskstats in linux.
