[ceph-users] new cluser ceph osd perf = 0

My ceph osd perf are all 0, do I need to enable module for this? osd_perf_query? Where should I find this in manuals? Or do I just need to wait? [@ target]# ceph osd perf osd commit_latency(ms) apply_latency(ms) 25 0 0 24 0 0 23 0 0 22 0 0 21 0 0 20 0 0 19 0 0 18 0 0
