--------------------------------------
Summary: Replace the "consumer-fetch-manager-metrics" by groupName
Key: KAFKA-17657
URL: https://issues.apache.org/jira/browse/KAFKA-17657
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
https://github.com/apache/kafka/blob/6ee46ea86530e019798ba0d4183164d7925dde63/clients/src/main/java/org/apache/kafka/clients/consumer/internals/FetchMetricsRegistry.java#L144
The `groupName` is derived from the input, so using the constant
"consumer-fetch-manager-metrics" for the group is not appropriate. While it
hasn't caused issues so far because the input has always been "consumer,"
addressing this now can help prevent potential bugs in the future.
