-------------------------------
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.
