Hello Paul,
thanks for your response/hints.
I discovered the following tool in the ceph source repository:
https://github.com/ceph/ceph/blob/master/src/tools/histogram_dump.py

Hi,

thing about them is that they are really easy to track.
But we have found them to be almost completely useless in the real world.
We track the op_*_latency metrics from perf dump and found them to be very
helpful, they
Hello ceph-users and ceph-devel list,
we got in production with our new shiny luminous (12.2.5) cluster.
This cluster runs SSD and HDD based OSD pools.
To ensure the service quality of the cluster and to have a baseline for
client latency optimization (i.e. in the area of deepscrub optimization)
