✅ Command:
./bin/kafka-consumer-groups.sh --describe --group consumer1 --bootstrap-server localhost:9092

This command provides detailed information about a specific Kafka consumer group named consumer1.

It shows:

Topic name

Partition number

Current offset (where the consumer group is in reading)

Log end offset (latest offset in the partition)

Lag (how far behind the consumer is)

Consumer ID, host, and client ID (if active)

This is essential for monitoring consumer lag, verifying consumer group activity, and debugging consumer performance issues.

Replace consumer1 with your actual consumer group ID.
