Thanks for sugestion with admin daemon but it looks like single osd
oriented. I have used perf dump on mon socket and it output some
interesting data in case of monitoring whole cluster:
{ "cluster": { "num_mon": 4,
"num_mon_quorum": 4,
"num_osd": 29,
"num_osd_up": 29,
"num_osd_in": 29,
"osd_epoch": 1872,
"osd_kb": 20218112516,
"osd_kb_used": 5022202696,
"osd_kb_avail": 15195909820,
"num_pool": 4,
"num_pg": 3500,
"num_pg_active_clean": 3500,
"num_pg_active": 3500,
"num_pg_peering": 0,
"num_object": 400746,
"num_object_degraded": 0,
"num_object_unfound": 0,
"num_bytes": 1678788329609,
"num_mds_up": 0,
"num_mds_in": 0,
"num_mds_failed": 0,
"mds_epoch": 1},
Unfortunately cluster wide IO statistics are still missing.
