System Properties Sample

+
+
+

Congrats on your shiny, new Open Liberty sample app!

+

This sample app uses a System Properties microservice to return the properties of the system that you're running.

+
+ +
+
+
+

System Properties

+
+
+ + + + +
PropertiesValue
+
+
+ +
+ +
+

This sample app, running on Open Liberty, uses a microservice to get the system properties from your laptop and displays them in your browser. It also displays health information about the microservice (or it will when you've added the capability) and metrics for the microservice. Scroll down to learn more.

+

Where to next, captain?

+

Set course for the Open Liberty guides!

+

All of the info you need to continue your journey is here, laid out in easy to follow steps and examples. Searching our current selection makes it easy to find the guide that will help make your next project a reality.
