This application helps to visualize what is occurring on your scaled OpenShift application. It is an EE6 application that queues and writes a count of the traffic it is receiving to a Mongo database. When you access the application, it uses the d3 javascript libraries to render a force layout view of your application and the connected gears as well as the traffic they have served.
If you want to create your own copy of this application, just run the following command:
rhc app-create scaleapp jbosseap mongodb-2 -s --from-code https://github.com/matthicksj/scaling-demo.git
Then, to add 'hits' to your application, hit the following URL:
http://YOUR_APP/rest/add
To drive some simple traffic, you can run something like:
for i in {1..10000}; do curl -s http://YOUR_APP/rest/add > /dev/null; usleep 50000; done
