> Key: KAFKA-17220
> URL: https://issues.apache.org/jira/browse/KAFKA-17220
> Project: Kafka
> Issue Type: New Feature
> Components: mirrormaker
> Reporter: Greg Harris
> Assignee: PoAn Yang
> Priority: Major
> Labels: needs-kip
>
> MirrorMaker2 provides some observability into it's operation, but lacks
> observability in the following areas:
> * Number of replicated topics/partitions
> * Number of consumer groups & consumer offsets
> * Background job success/failure/latency/duration
> * Checkpoint task startup time
> * Consumer group translation lag/expected redelivered data
> * Error metrics for failed offset translations
> These concepts should be more clearly defined and included in a general
> observability KIP for MM2.
