Kafka JMX monitoring

By default, Kafka does not allow remote JMX connections over RMI. To enable them, you need to:

• Define the connection when running Kafka broker.
  Windows example:

set JMX_PORT=9999 bin/kafka-server-start.bat config/server-1.properties set JMX_PORT=10000 bin/kafka-server-start.bat config/server-2.properties 

• Define the connection within the run script kafka-server-start.sh.
  Unix/Linux example:
  Add following options in the startup script for each Kafka server:

export KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote=true - Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=KAFKA-SERVER1" export JMX_PORT=9999 export KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote=true - Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=KAFKA-SERVER2" export JMX_PORT=9999

As per the Confluent article below, each component uses its own variable - https://docs.confluent.io/platform/current/kafka/monitoring.html
