    ApsaraMQ for Kafka:Why do I fail to view the subscriptions of a consumer group in the Message Queue for Apache Kafka console?

    Last Updated:Dec 12, 2023

    Symptoms

    I have started the consumption thread of a consumer group, but no subscriptions from the consumer group to the data source topic are displayed on the Subscriptions tab of the Topic Details page or the Consumer Status tab of the Group Details page in the ApsaraMQ for Kafka console.

    Causes

    • The configured subscription is not successful because the consumer settings are invalid or a network exception occurs on the consumer.

    • You use the assign mode to manually specify a specific partition to which the consumer subscribes, but you do not commit the consumer offset.

    Solutions

    1. Troubleshoot the issues on the consumer. For more information, see Best practices for consumers.

    2. Troubleshoot the network issues on the consumer. For more information, see What do I do If the attempt to ping the endpoint of Message Queue for Apache Kafka failed?.

    3. Commit the consumer offset. For more information, see Commit consumer offsets.
