----------------------------------
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.
