> Key: FLINK-8419
> URL: https://issues.apache.org/jira/browse/FLINK-8419
> Project: Flink
> Issue Type: Bug
> Components: Kafka Connector, Metrics
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Fix For: 1.5.0, 1.4.1
>
>
> Currently, the per-partition offset metrics are registered via the
> {{AbstractFetcher#addOffsetStateGauge}} method. That method is only ever
> called for the initial startup partitions, and not for dynamically discovered
> partitions.
> We should consider adding some unit tests to make sure that metrics are
> properly registered for all partitions. That would also safeguard us from
> accidentally removing metrics.
