Message Conversions

Menu

The Message Conversions metric group contains metrics regarding the amount of message conversions occurring in the cluster. The metrics available are:

  • Fetch Message Conversions Per Sec
  • Produce Message Conversions Per Sec

 

Fetch Message Conversions Per Sec

The Fetch Message Conversions Per Sec metric displays the one minute rate, mean rate, and the number of messages from consumer requests to get new data that require message format conversion. Message conversions introduce a processing overhead as messages between the Kafka clients and brokers require conversion in order to be understood by both parties. Any fetch message conversions being performed indicates that some Kafka consumers are using a different version of Kafka to the Kafka brokers. To avoid unnecessary message conversions, ensure all Kafka clients are using the same version of Kafka as the Kafka brokers.

Expected value: 0

Produce Message Conversions Per Sec

The Produce Message Conversions Per Sec metric displays the one minute rate, mean rate, and the number of messages from producer requests to send data that require message format conversion. Message conversions introduce a processing overhead as messages between the Kafka clients and brokers require conversion in order to be understood by both parties. Any produce message conversions being performed indicates that some Kafka producers are using a different version of Kafka to the Kafka brokers. To avoid unnecessary message conversions, ensure all Kafka clients are using the same version of Kafka as the Kafka brokers.
