How to enable remote JMX on Kafka brokers (for JmxTool)?

Question

I enabled JMX on Kafka brokers by adding

KAFKA_JMX_OPTS=\"-Dcom.sun.management.jmxremote=true
                -Dcom.sun.management.jmxremote.authenticate=fa         


        

Answer 1

Kafka has provided all you need. When your start your server, activate the KAFKA_JMX_OPTS arg by using these command:

$KAFKA_JMX_OPTS JMX_PORT=[your_port_number] ./kafka-server-start.sh -daemon ../config/server.properties

Using those command, you activated JMX Remote and related port. Then you can connect your JConsole or another monitoring tools.

Answer 2

vim kafka_2.11-0.10.1.1/bin/kafka-run-class.sh

and then add the first two lines and comment as I have done for other lines, (Note : after doing this Kafka scripts cannot be used for client operations for listing topics.. for your client operations you need to use a separate scripts , download again in different locations and use)

export JMX_PORT=9096
KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=<ipaddress> -Dcom.sun.management.jmxremote.port=$JMX_PORT -Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT"



# JMX settings
#if [ -z "$KAFKA_JMX_OPTS" ]; then
# KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxremote.ssl=false "

#fi

# JMX port to use
#if [  $JMX_PORT ]; then
#  KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT "
#fi
