Grant Henke reassigned KAFKA-2588: ---------------------------------- Assignee: (was: Grant Henke) > ReplicaManager partitionCount metric should actually be replicaCount > -------------------------------------------------------------------- > > Key: KAFKA-2588 > URL: https://issues.apache.org/jira/browse/KAFKA-2588 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 0.10.0.0, 0.11.0.0, 1.0.0 > Reporter: Grant Henke > Priority: Major > Labels: needs-kip > > The metrics "partitionCount" in the ReplicaManager actually represents the > count of replicas. > As an example if I have a cluster with 1 topic with 1 partitions and a > replication factor of 3. The metric (aggregated) would show a value of 3. > There is a metric called "LeaderCount" that actually represents the > "partitionCount". In my example above the metric (aggregated) would show a > value of 1. > We do need to consider compatibility of consuming systems. I think the most > simple change would be to: > - Adjust the "partitionCount" metric to be the same value as "LeaderCount" > - Add a "replicaCount" metric which contains the values "partitionCount" does > today > - Leave "LeaderCount" in for compatibility > Documentation will need to be updated as well. -- This message was sent by Atlassian Jira (v8.3.4#803005)
