Hello sorry for my english, I have the same problem, i don't know how to transmit my workaround to the project's maintener.
I made a workarround, for this: edit /usr/lib64/collectd/plugins/ceph/ceph_pg_plugin.py
change lines:
79 data[ceph_cluster][osd_id]['apply_latency_ms'] = osd['fs_perf_stat']['apply_latency_ms']
80 data[ceph_cluster][osd_id]['commit_latency_ms'] = osd['fs_perf_stat']['commit_latency_ms']
to:
79 data[ceph_cluster][osd_id]['apply_latency_ms'] = osd['perf_stat']['apply_latency_ms']
80 data[ceph_cluster][osd_id]['commit_latency_ms'] = osd['perf_stat']['commit_latency_ms']
Tested on luminous 12.2.7
