Hi Shridhar,
Did u mean 'ceph rbd perf image stats' or  'rbd perf image iostat' ?



for monitor intergration,  you can enable mgr prometheus module and get metrics for each image in specified pools

Subject:&nbsp; per rbd performance counters



Hello,

Is there a way to get read/write I/O statistics for each rbd device for
each mapping?

For example, when an application uses one of the volumes, I would like to
find out what performance (avg read/write bandwidth, IOPS, etc) that
application observed on a given volume. Is that possible?

Thanks,
Shridhar
