Guozhang Wang created KAFKA-12428: ------------------------------------- Summary: Add a last-heartbeat-seconds-ago metric to Kafka Consumer Key: KAFKA-12428 URL: https://issues.apache.org/jira/browse/KAFKA-12428 Project: Kafka Issue Type: Improvement Components: consumer Reporter: Guozhang Wang
I have encountered several issues in the past where heartbeat requests are not sent [1,2] (either in time, or ever), and today it is a bit hard to get to that from the logs. I think it is better to add a metric as "last-heartbeat-seconds-ago" where when rebalances were triggered we can immediately find out if this is the root cause. 1. https://issues.apache.org/jira/browse/KAFKA-10793 2. https://issues.apache.org/jira/browse/KAFKA-10827 -- This message was sent by Atlassian Jira (v8.3.4#803005)
