Daniel Wojda created KAFKA-6176: ----------------------------------- Summary: numDroppedMessages metric should not be incremented when no data are lost Key: KAFKA-6176 URL: https://issues.apache.org/jira/browse/KAFKA-6176 Project: Kafka Issue Type: Bug Components: metrics Affects Versions: 1.0.0 Reporter: Daniel Wojda Priority: Minor
Mirror Maker can be configured to not lose the data when producing failed. However when Mirror Maker is configured correctly and no messages are lost, *numDroppedMessages* metric is increased in case of producer failure. It is misleading for people who monitor Mirror Maker. Could we increase that metric when messages are really dropped? Or at least change the name to "numProducerFailuers"? -- This message was sent by Atlassian JIRA (v6.4.14#64029)
