zhifeng.peng updated KAFKA-12186:
---------------------------------
Description:
TotalFetchRequestsPerSec: kafka.server:type=BrokerTopicMetrics,
name=TotalFetchRequestsPerSec
Fetch: kafka.network:type=RequestMetrics, name=RequestsPerSec, request=Fetch
FetchFollower: kafka.network:type=RequestMetrics, name=RequestsPerSec,
request=FetchFollower
I found a big difference between TotalFetchRequestsPerSec and sum of Fetch and
FetchFollower Request Rate.
TotalFetchRequestsPerSec for all topic:

broker fetch and fetchFollower rate:
!image-2021-01-13-19-00-22-997.png!
was:
TotalFetchRequestsPerSec: kafka.server:type=BrokerTopicMetrics,
name=TotalFetchRequestsPerSec
Fetch: kafka.network:type=RequestMetrics, name=RequestsPerSec, request=Fetch
FetchFollower: kafka.network:type=RequestMetrics, name=RequestsPerSec,
request=FetchFollower
I found a big difference between TotalFetchRequestsPerSec and sum of Fetch and
FetchFollower Request Rate.
TotalFetchRequestsPerSec for all topic:
broker fetch and fetchFollower rate:
> TotalFetchRequestsPerSec not equal to sum of Fetch and FetchFollower Request
> Rate
