Hi, all As my understand, command "ceph daemon osd.x perf dump objecters" should output the perf data of osdc(librados). But when i use this command, why all those values are zero expcept map_epoch and map_inc. Follow is the result(It has fio test with rbd ioengine on the cluster): $ sudo ceph daemon osd.10 perf dump objecter { "objecter": { "op_active": 0, "op_laggy": 0, "op_send": 0, "op_send_bytes": 0, "op_resend": 0, "op_ack": 0, "op_commit": 0, "op": 0, "op_r": 0, "op_w": 0, "op_rmw": 0, "op_pg": 0, "osdop_stat": 0, "osdop_create": 0, "osdop_read": 0, "osdop_write": 0, "osdop_writefull": 0, "osdop_append": 0, "osdop_zero": 0, "osdop_truncate": 0, "osdop_delete": 0, "osdop_mapext": 0, "osdop_sparse_read": 0, "osdop_clonerange": 0, "osdop_getxattr": 0, "osdop_setxattr": 0, "osdop_cmpxattr": 0, "osdop_rmxattr": 0, "osdop_resetxattrs": 0, "osdop_tmap_up": 0, "osdop_tmap_put": 0, "osdop_tmap_get": 0, "osdop_call": 0, "osdop_watch": 0, "osdop_notify": 0, "osdop_src_cmpxattr": 0, "osdop_pgls": 0, "osdop_pgls_filter": 0, "osdop_other": 0, "linger_active": 0, "linger_send": 0, "linger_resend": 0, "linger_ping": 0, "poolop_active": 0, "poolop_send": 0, "poolop_resend": 0, "poolstat_active": 0, "poolstat_send": 0, "poolstat_resend": 0, "statfs_active": 0, "statfs_send": 0, "statfs_resend": 0, "command_active": 0, "command_send": 0, "command_resend": 0, "map_epoch": 2180, "map_full": 0, "map_inc": 83, "osd_sessions": 0, "osd_session_open": 0, "osd_session_close": 0, "osd_laggy": 0 } } Anyone could tell why?
