> 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
