I'm using JMX to retrieve Cassandra metrics. I notice that Max and Count are
cumulative and aren't reset. How often are the stats for Mean,
99tthPercentile, etc reset back to zero?
For example, 99thPercentile shows as 1.5 mls. Over how many minutes?
ClientRequest/Read/Latency:
LatencyUnit = MICROSECONDS
FiveMinuteRate = 1.12
FifteenMinuteRate = 1.11
RateUnit = SECONDS
MeanRate = 1.65
OneMinuteRate = 1.13
EventType = calls
Max = 237,373.37
Count = 961,312
50thPercentile = 383.2
Mean = 908.46
Min = 95.64
StdDev = 3,034.62
75thPercentile = 626.34
95thPercentile = 954.31
98thPercentile = 1,443.11
99thPercentile = 1,472.4
999thPercentile = 1,858.1
