Can someone confirm if json+ format is used the latency reported in the bins (~1200) are mid-point not the max? Does the --status-interval=1sec makes reporting average value in bins. Does adding the log_max_value=1 , will ensure that always max is recorded in the latency bin? I have used this for the non-json format but then average latency reporting per interval is lost.
