Research direction

Examine Storm's existing metrics reporter mechanism in 'storm server/src/main/java/org/apache/storm/metrics/'. Consider adding an HTTP endpoint using Prometheus Java Simpleclient to expose metrics for nimbus and supervisor daemons. Review configuration options for enabling/disabling the endpoint. Look at similar implementations in other Apache projects for reference.
