Kafka consumer metricset
editKafka consumer metricset
editThis 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 Consumers implemented in java and expose JMX metrics through jolokia agent.
Compatibility
editThe module has been tested with Kafka 2.1.1 and 2.2.2. Other versions are expected to work.
Usage
editThe Consumer metricset requires Jolokiato fetch JMX metrics. Refer to the link for more information about Jolokia.
Note that the Jolokia agent is required to be deployed along with the JVM application. This can be achieved by
using the KAFKA_OPTS environment variable when starting the Kafka consumer application:
export KAFKA_OPTS=-javaagent:/opt/jolokia-jvm-1.5.0-agent.jar=port=8774,host=localhost ./bin/kafka-console-consumer.sh --topic=test --bootstrap-server=localhost:9091
Then it will be possible to collect the JMX metrics from localhost:8774.
For a description of each field in the metricset, see the exported fields section.
