You can get all the details from the admin socket of the OSDs: ceph daemon osd.X perf dump
(must be run on the server the OSD is running on) Examples of relevant metrics are: bluestore_allocated/stored and the bluefs block for metadata. Running perf schema might contain some details on the meaning of the individual metrics. -- Paul Emmerich Looking for help with your Ceph cluster?
