----------------------------------
Resolution: Done
> Add RocksDB statistics via Streams metrics
> ------------------------------------------
>
> Key: KAFKA-6498
> URL: https://issues.apache.org/jira/browse/KAFKA-6498
> Project: Kafka
> Issue Type: Improvement
> Components: metrics, streams
> Reporter: Guozhang Wang
> Assignee: Bruno Cadonna
> Priority: Major
> Labels: kip
>
> RocksDB's own stats can be programmatically exposed via
> {{Options.statistics()}} and the JNI `Statistics` has indeed implemented many
> useful settings already. However these stats are not exposed directly via
> Streams today and hence for any users who wants to get access to them they
> have to manually interact with the underlying RocksDB directly, not through
> Streams.
> We should expose such stats via Streams metrics programmatically for users to
> investigate them without trying to access the rocksDB directly.
