Supervising Java Application

[Chaima TOUIL]

Hi, 

I would like to supervise a #Java Application Apache Karaf and export personalized metrics. I used #Decanter #Prometheus, and i've installed decanter features and i must add some modifications in my code java(modules, packages,...) to authorize collecting data from the application.

Any ideas about this please? What should i add in my apllication source code?
