Subject Kafka TotalTimeMs time interval
Date Fri, 11 May 2018 14:01:10 GMT
Hi All,

I have a question regarding Kafka TotalTimeMs metrics and similar metrics.
What is the time interval for which the metrics is calculated. For example
let us take the
MBean kafka.network:name=TotalTimeMs,request=Produce,type=RequestMetrics as
an example. In this metric, there is a Mean and StdDev. Is the Mean, the
average total time for all the Produce requests that the broker received
from the time the brokder started, or is it for a time period. Can this
metric be used for a following use case - "Has the average request
processing time for the last 5 mins increased when compared to the previous
period so that I can deduce if the system has slowed down". If the mean is
from the broker start time, we cannot get the mean value for the last 5
minutes right? Sorry if the question is a very simple one, but I could not
get any proper documentation for the same.
