Jess updated KAFKA-19532:
-------------------------
Description:
Following up on the discussion in this Kafka discussion thread:
https://lists.apache.org/thread/w4n0tbpn08ocnyq51vj0mjhxmbn42fcv
It appears that there is a possible bug between the metrics
`kafka.network:type=RequestMetrics,name=RequestsPerSec,request=
\{Produce|FetchConsumer|FetchFollower},version=([0-9]+)` and these two metrics:
*
`kafka.server:type=BrokerTopicMetrics,name=TotalProduceRequestsPerSec,topic=([-.\\w]+)`
*
`kafka.server:type=BrokerTopicMetrics,name=TotalFetchRequestsPerSec,topic=([-.\\w]+)`
Both represent requests per second, which makes it especially confusing when I
see completely different values for both. I would assume data would line up for
these metrics, so maybe I am misunderstanding how these metrics work
(`kafka.network` vs `kafka.server`) or whether there is simply a bug (as
suggested by the discussion thread) but I would like to get to the bottom of
this confusion.
