Why Is the Number of Stacked Messages in Consumer Offset Different from That in Monitoring?
Symptom
The Consumer Offset tab on the consumer group details page shows that messages are stacked in a topic, which is inconsistent with the Accumulated Messages (Consumer Available Messages) metric on the consumer group monitoring page.
Conclusion
Number of stacked messages = Latest offset – Offset. The Latest Offset and Offset on the Consumer Offset tab page are data sampled at the same time. However, on the consumer group monitoring page, these metrics are sampled at an interval of 1 to 2s. As a result, the message stack within the interval cannot be reflected.
