Kafka broker metricsetedit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

This metricset periodically fetches JMX metrics from Kafka Broker JMX.


The module has been tested with Kafka 2.1.1 and 2.2.2. Other versions are expected to work.


The Broker metricset requires Jolokiato fetch JMX metrics. Refer to the link for instructions about how to use Jolokia.

Note that the Jolokia agent is required to be deployed along with the Kafka JVM application. This can be achieved by using the KAFKA_OPTS environment variable when starting the Kafka broker application:

export KAFKA_OPTS=-javaagent:/opt/jolokia-jvm-1.5.0-agent.jar=port=8779,host=localhost
./bin/kafka-server-start.sh ./config/server.properties

Then it will be possible to collect the JMX metrics from localhost:8779.

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.


For a description of each field in the metricset, see the exported fields section.
