>             Project: Apache NiFi
>          Issue Type: New Feature

> When attempting to troubleshoot a custom component in a NiFi installation, at least two pieces of information may be needed:
> 1. Which version of NiFi are you using?
> 2. Which version of the component are you using?
> Currently, the only available mechanism(s) (for determining the version of the component), i.e., 
>  - examining the lib directory to get the version of the nar, or 
>  - opening the log to the point where NiFi first "opened"/loaded the nar
>  requires log in access to the machine where NiFi is running.  
> Many environments (particularly corporate) are likely to be wary of granting log in access to all NiFi users (not to speak of the difficulty in explaining to a generic user how to find the version number of the component in question).
> Recommend making custom component/nar version numbers accessible in the NiFi User Interface (UI).
> Here are a few options for consideration:
>  - Include a list of nars (and their version numbers) alongside the Apache NiFi version number (currently provided in the about window/dialog). 
>  - For each components documentation, include the name and version of the deployable unit (nar) from which it was loaded.
>  - Add the information to the face of processor(s), e.g., enable a portion of the face of a processor (perhaps an i (for information) or a question mark icon) that upon mouse over, displays information about the processor, including the deployable unit (nar name and version) from which it came.
