This project contains Brooklyn GUI support for a JMX console, allowing a JMX endpoint sensor on an entity to be linked in the Brooklyn console to a web-app which allows drill-down into JMX data points.
The code snippet is very small, and it is embedded in the class SampleJmxApp in this demo. That class starts a Tomcat server and sets up an active link from the JMX endpoint exposed by Tomcat.
You must have the projects github.com:brooklyncentral/brooklyn and github.com:ahgittin/jmx-console-webapp checked out and built
(with mvn clean install) and available in your local m2 repository.
For more information on the underlying JMX console see the github.com:ahgittin/jmx-console-webapp project.
To compile this project simply mvn clean install in the brooklyn-jmx-console-demo project, then run the JmxWarRunner (to start the JMX web console) and SampleJmxApp (to start the app in Brooklyn) classes.
(You can also start SampleJmxApp in the other standard ways offfered by
Brooklyn.)
To use in your own project, simply set up your POM as per this project and follow the instructions in the SampleJmxApp class.
Here is a sequence of screenshots showing the application:
