I believe that's the case,

The recovery_state "latencies" are all about how long your PGs are in various
states of recovery; they're not per-operation latencies. 3 days still seem

Thanks Haomai,
So are all latency values calculated in seconds?

178/184229=0.00097 s
178/184229=0.00097 s = 0.97ms

Hi,
I'm seeing really low latency values, to the extent that they don't seem
realistic.
Snippet from the latest perf dump for this OSD:
"op_r_latency": { "avgcount": 184229,
"sum": 178.07771},
Long run avg = 178.07771/184229 = 0.00097 ms? Is it correct that latency values
have m
