time-between-poll-avg | kafka.consumer:type=consumer-metrics,client-id=([-.\w]+) | The average delay between invocations of poll(). |
time-between-poll-max | kafka.consumer:type=consumer-metrics,client-id=([-.\w]+) | The max delay between invocations of poll(). |
last-poll-seconds-ago | kafka.consumer:type=consumer-metrics,client-id=([-.\w]+) | The number of seconds since the last poll() invocation. |
poll-idle-ratio -avg | kafka.consumer:type=consumer-metrics,client-id=([-.\w]+) | The average fraction of time the consumer's poll() is idle as opposed to waiting for the user code to process records. |

The last-poll-seconds-ago metric will measure the time since the user last called poll() to provide more insight into how/when the user code calls poll() .
poll-idle-ratio-avg
There will be an additional metric that measures the idle time of the consumer in waiting for the user to process records returned from poll:
