Viewing the Consumer Group List (Kafka CLI)

• For a Kafka instance with ciphertext access disabled, run the following command in the /bin directory of the Kafka client:

  ./kafka-consumer-groups.sh --bootstrap-server ${connection-address} --list

• For a Kafka instance with ciphertext access enabled, do as follows:
  1. (Optional) For the Kafka security protocol, is SASL_PLAINTEXT or SASL_SSL used?
     • SASL_PLAINTEXT: Skip this step if the username and password are already set. In other cases, create the ssl-user-config.properties file in the /config directory of the Kafka client. Add the username and password by referring to 3.
     • SASL_SSL: Skip this step if the username, password, and SSL certificate are already set. In other cases, create the ssl-user-config.properties file in the /config directory of the Kafka client. Add the username and password, and the SSL certificate configuration by referring to 3.
  2. Run the following command in the /bin directory of the Kafka client:

     ./kafka-consumer-groups.sh --bootstrap-server ${connection-address} --list --command-config ./config/ssl-user-config.properties
