Hi If i look at these numbers(getting from kafka) then according to that Ms should be microseconds.
NumFetchRequests=5350287 TotalFetchRequestMs=56605349834 FetchRequestsPerSecond=92.76876273667219 *Calculation of **FetchRequestsPerSecond manually:* FetchRequestsPerSecond = NumFetchRequests/TotalFetchRequestTime in seconds = 5350287/56605 = 94.5 ~ 92.76 . But if i look at these 2 parameters values then it seems to be in milliseconds: AvgFetchRequestMs=0.008763 MaxFetchRequestMs=3.610314 I am still not able to finalize that reported time is in milliseconds or microseconds.
