Liquan Pei reassigned KAFKA-3556: --------------------------------- Assignee: Liquan Pei > Improve group coordinator metrics > --------------------------------- > > Key: KAFKA-3556 > URL: https://issues.apache.org/jira/browse/KAFKA-3556 > Project: Kafka > Issue Type: Improvement > Reporter: Jason Gustafson > Assignee: Liquan Pei > > We currently don't have many metrics to track the behavior of the group > coordinator (especially with respect to the new consumer). On a quick pass, I > only saw a couple gauges in GroupMetadataManager for the number of groups and > the number of cached offsets. Here are some interesting metrics that may be > worth tracking: > 1. Session timeout rate > 2. Rebalance latency/rate > 3. Commit latency/rate > 4. Average group size > 5. Size of metadata cache > Some of these may also be interesting to track per group. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
