You can update the Java options for the services through the CDP UI.

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

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:

export KAFKA_OPTS="$KAFKA_OPTS -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

        export KAFKA_OPTS="$KAFKA_OPTS -javaagent:$AGENT_PATH=/opt/acceldata/jmx/config/enabled/vm_kafka3_connect.xml"

    elif [[ "$CURRENT_CMD_STRING" == *"kafka start"* ]] || [[ "$CURRENT_CMD_STRING" == *"kafka-server-start"* ]]; then
