---------------------------------

             Summary: Ability to report what components a flow is actually using
                 Key: NIFI-9498
                 URL: https://issues.apache.org/jira/browse/NIFI-9498
             Project: Apache NiFi
          Issue Type: New Feature
            Reporter: Otto Fowler


Nifi may have 100s of NARS and their components loaded, but for any flow the actual working set of NARS and components is a subset.

We often recommend that people remove NARS that aren't used from the nifi working set for various reasons, but there is no concrete way to identify what NARs you can remove.

NIFI should provide some set of features around allowing visibility into what the working set of NARS and components are for a given flow.

There are different levels of feature around this idea to be explored:
* a cli command that produces a report document from a live instance or from flow definition file
* a ui component that visualizes the graph and can export a report
* Actions from these things, to remove or restrict what is loaded in a cluster ( imagine a cluster whitelist for NARS that is share in the cluster )
* ???
* profit!!!
