Kafka consumer list

Question

I need to find out a way to ask Kafka for a list of topics. I know I can do that using the kafka-topics.sh script included in the bin\\ directory.

Answer 1

You can also use kafkactl for this:

# get all consumer groups (output as yaml)
kafkactl get consumer-groups -o yaml

# get only consumer groups assigned to a single topic (output as table)
kafkactl get consumer-groups --topic topic-a

Sample output (e.g. as yaml):

name: my-group
protocoltype: consumer
topics:
 - topic-a
 - topic-b
 - topic-c
