> KIP-517: Add consumer metric indicating time between poll calls
> ---------------------------------------------------------------
>
> Key: KAFKA-8874
> URL: https://issues.apache.org/jira/browse/KAFKA-8874
> Project: Kafka
> Issue Type: New Feature
> Components: consumer, metrics
> Reporter: Kevin Lu

> Priority: Minor

> [https://cwiki.apache.org/confluence/display/KAFKA/KIP-517%3A+Add+consumer+metric+indicating+time+between+poll+calls]
> It would be beneficial to add a metric to record the average/max time between
> calls to poll as it can be used by both Kafka application owners and
> operators to:
> * Easily identify if/when max.poll.interval.ms needs to be changed (and to
> what value)
> * View trends/patterns
> * Verify max.poll.interval.ms was hit using the max metric when debugging
> consumption issues (if logs are not available)
> * Configure alerts to notify when average/max time is too close to
> max.poll.interval.ms
