> 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.
