I stumbled on this problem earlier, port 9926 isn't being opened. See also thread "Grafana dashboards is missing data". A tracker is already opened to fix the issue: https://tracker.ceph.com/issues/67975

Prometheus metrics seem to be broken, too:
ceph_osd_op_r_latency_sum
ceph_osd_op_w_latency_sum
Both of them for example are not reported by the ceph mgr metrics exporter:
curl http://192.168.XXX.XXX:9283/metrics |grep ceph_osd_
I get some merics like "ceph_osd_commit_latency_ms" or "ceph_osd_apply_latency_ms" but none of the "op_r / op_w" metrics. Do the lable names have switched and my grafana dashboard is outdated? Or are they missing at the exporter level?
Thanks

Hi,
i'm running a Ceph v18.2.4 cluster. I'm trying to build some latency monitoring with the
ceph daemon osd.4 perf dump
cli command. On most of the OSDs i get all the metrics i need. On some OSDs i only get zero values:
osd.op_latency.avgcount: 0
I already tried restarting the OSD process which didn't help. I also tried to reset the metrics via
ceph daemon osd.4 perf reset all
but that didn't help either. How can that be that some OSDs don't show values here? How can i fix that?
Thanks
Regards,
