Grant Henke created KAFKA-2588: ---------------------------------- Summary: 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: 0.8.2.1 Reporter: Grant Henke Assignee: Grant Henke
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 (v6.3.4#6332)
