I have to enable the following configuration for tomcat running in elastic beanstalk environment

-Dcom.sun.management.jmxremote.port=9000 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

I have absolutely no idea where I have to make these changes.

Elastic Beanstalk Configuration

64bit Amazon Linux 2016.09 v2.3.1 running Tomcat 8 Java 8

I believe elastic beanstalk create different set of folder structure for tomcat8

# whereis tomcat8
tomcat8: /usr/sbin/tomcat8 /etc/tomcat8 /usr/libexec/tomcat8 /usr/share/tomcat8

My Issue is resolved following this link https://bobmarksblog.wordpress.com/2016/08/08/monitoring-elasticbeanstalk-tomcat-instances-using-visualvm-via-ssh/

  • Please write a brief description of the link in an answer (not editing the question) and mark it as accepted :) – Alfabravo Dec 20 '17 at 18:12
  • Note: it wouldn't work for load-balancing environments, when you have more than 1 node – ALex_hha Jan 26 '18 at 8:19

The solution is a lot simpler than I thought.

To enable JMX in AWS Elastic Beanstalk you must add JVM command line configuration ->

Select Elastic Beanstalk environment -> 
Configuration -> Software Configuration -> 
Add following to “JVM command line options:”

in text box

 -Dcom.sun.management.jmxremote.port=9000 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

It will automatically trigger the changes and will update the servers, now in a security group (assigned to your instances), you must allow this port 9000.

Now you can connect to any of the instances at a time but viewing is public IP address from AWS console (web).

Please have a look at this link for more details. https://bobmarksblog.wordpress.com/2016/08/08/monitoring-elasticbeanstalk-tomcat-instances-using-visualvm-via-ssh/
