Kafka consumer group for supervisor task

I am new to druid.

How to find consumer group details for supervisor task (KIS - kafka indexing service ) running on overlord ?

Can anyone please help on this query ?

Check here: http://druid.io/docs/latest/development/extensions-core/kafka-ingestion.html#get-supervisor-status-report

Specifically, I believe this is because KIS doesn’t actually use the standard consumer group API with metadata storage in ZK or Kafka — though please correct me if I’m wrong!

Yeah, I also think so. Offsets are stored inside Druid, and no consumer group exist on the Kafka brokers. But on this HTTP url on overlord you can get lag and current offsets:
GET /druid/indexer/v1/supervisor//status
