[jira] [Created] (KAFKA-2306) New producer should emit metrics for buffer exhaustion

Dong Lin created KAFKA-2306:
-------------------------------

             Summary: New producer should emit metrics for buffer exhaustion
                 Key: KAFKA-2306
                 URL: https://issues.apache.org/jira/browse/KAFKA-2306
             Project: Kafka
          Issue Type: Bug
            Reporter: Dong Lin


In the old producer we have droppedMessageRate that allows user to monitor the number of messages dropped when buffer is full and block on buffer full is set to false. This metric is useful in operation. However, in the new producer we don't have this a metric.

The "errors" sensor in new-producers measures per-record error that is not limited to those caused by BufferExhaustedException. Thus it is not good enough.
