I am trying to monitor KStream rocksdb store.
As per confluent documentation, RocksDB property-based metrics of type stream-state-metrics should be available at a metric recording level of INFO.

I could observe the MBeans for the same from JConsole.
RocksDB metrics

However, kStream.metrics() does not return rocksDb Metrics.
Setting metric recording level to DEBUG does not help either.

Found the following two issues that are similar (but not the same).
However, those are fixed in versions after 2.4.X

Also found the following question on SO. But it points to KAFKA-9675.

What could be wrong?

Note:
KStream version : 3.0.0
Broker version: 0.11.0.0

  • If your broker version is really 0.11.0.0 as you say, that's the problem. That's an ancient Kafka version. Try to install a version newer than 2.4 on the broker side, and see if you can get the metrics to show up. – mjuarez Jul 30 '22 at 02:58
