[jira] [Commented] (KAFKA-1800) KafkaException was not recorded at the per-topic metrics

    [ https://issues.apache.org/jira/browse/KAFKA-1800?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14230111#comment-14230111 ] 

Jay Kreps commented on KAFKA-1800:
----------------------------------

Is it important to count this exception at the topic level? Maybe just count it at the global level?

> When KafkaException was thrown from producer.send() call, it is not recorded on the per-topic record-error-rate, but only the global error-rate.
> Since users are usually monitoring on the per-topic metrics, loosing all dropped message counts at this level that are caused by kafka producer thrown exceptions such as BufferExhaustedException could be very dangerous.
