Why Can't I View the Monitoring Data?

If topic monitoring data is not displayed, the possible causes are as follows:

• The topic name starts with a special character, such as a number sign (#).
• No topic is created in the Kafka instance.

Solution:

• Delete topics whose names contain special characters.
• Create a topic.

If consumer group monitoring data is not displayed, the possible causes are as follows:

• The consumer group name starts with a special character, such as a number sign (#).
• No consumers in the group have connected to the instance.

Solution:

• Delete consumer groups whose names contain special characters.
• Consume messages using this consumer group.
