Configure the Java Options for Services Using JMX Agent in CDP

You can update the Java options for the services through the CDPUI.

Below are the detailed, service-wise details for all services supported by the JMX agent.

Prerequisite

/opt/acceldata/jmx/config/enabled

For example, for Cruise Control, verify thatvm_cruise_control.xml exists in this directory. If the required XML file is missing, adding the JMX configuration and restarting the service may cause the service to fail to start.

Kafka

If Kafka Connect is NOT enabled:

1. In the CM UI, navigate to Kafka > Configuration.
2. Search for Additional Broker Java Options (broker_java_opts).
3. Add the following line at the end:

-javaagent:/opt/acceldata/jmx/lib/jmxtrans-agent.jar=/opt/acceldata/jmx/config/enabled/vm_kafka.xml"

If Kafka Connect is enabled:

Add the following snippet at the end of the kafka-env template:

AGENT_PATH="/opt/acceldata/jmx/lib/jmxtrans-agent.jar"
if [[ "$KAFKA_OPTS" != *"$AGENT_PATH"* ]]; then
 CURRENT_CMD_STRING=$(ps -p $$ -o args=)
 if [[ "$CURRENT_CMD_STRING" == *"kafka-connect"* ]]; then
 -javaagent:$AGENT_PATH=/opt/acceldata/jmx/config/enabled/vm_kafka3_connect.xml"
    elif [[ "$CURRENT_CMD_STRING" == *"kafka start"* ]] || [[ "$CURRENT_CMD_STRING" == *"kafka-server-start"* ]]; then
        -javaagent:$AGENT_PATH=/opt/acceldata/jmx/config/enabled/vm_kafka3.xml"
 fi
fi
