> Control plane events, such as {{AllocatedEvaluator}} and {{ActivatedContext}},  can easily be tracked by adding {{EventListener}} s to {{DriverConfiguration}} without disturbing the application. It would be good to make a Service that listens to and reports the events. Also, the Service can be enhanced to work as a general profiler by adding more event types for profiling.
> This service 
>  1) should be integrated with existing REEF applications.
>  2) should report events in a well-defined format.
>  3) can print the events to the file system.
>  4) can report the events to an external web server using RESTful API.
> This can be used to implement a realtime observation web UI like [spark-spree|http://www.hammerlab.org/2015/07/25/spree-58-a-live-updating-web-ui-for-spark/].
