Subject [jira] [Created] (KAFKA-7942) Monitoring consumer lag by time
Date Mon, 18 Feb 2019 10:15:00 GMT
Yining Liu created KAFKA-7942:

             Summary: Monitoring consumer lag by time
                 Key: KAFKA-7942
                 URL: https://issues.apache.org/jira/browse/KAFKA-7942
             Project: Kafka
          Issue Type: Wish
          Components: consumer, metrics
            Reporter: Yining Liu

Currently, we can collect num of messages consumer lagging behind producer. However, if messages
come into a partition sporadically, we are not easy to define consumer lag alert threshold.
If we know how long consumer lagging behind latest message, it must be helpful.

There are two options:
 # expose per partition lag time by consumer jmx metrics
 # expose consumer lag time in kafka-consumer-groups.sh
