To set this up you will need to do the following:
- Have an AWS account
- Set up a IAM Role to be applied to a running instance which you want to monitor
- Start EC2 instance hosting Tomcat which has outbound access to the internet
- Download the AWS CLI package
- Create a script to extract the JVM stats and publish to CloudWatch using the CLI
- Set execution of the script in cron to publish the metrics at your desired frequency
