Description
After the recent fix https://github.com/ceph/ceph/pull/42217, we'd need to review all the Grafana dashboards to ensure that if no metric unit is made explicit (e.g.: milliseconds in ceph_osd_apply_latency_ms
), they'd be using SI units or base (seconds, bytes, bits) and not multiples/submultiples.
We should put extra emphasis on latency related metrics (*_latency_*
): ceph_osd_op_r_latency_sum, etc.
An case raised by Ben England:
OSD device details Y-axis units need to be correct. "MBs" -> MBps or MB/s. It would be really interesting to have a set of graphs with *all* the OSDs in them (if there are less than 20 of them). If there are more than that, just show me the "top" OSDs with respect to each metric.

Would the difference between Bps and bps be in-scope of this issue? Noticed that in the "Network Load" graph the y scale is in "B/s" such as "3.4 GB/s" but I am quite certain it is actually displaying bits per second ("b/s") and not bytes per second ("B/s").
