---------------------------------
Resolution: Duplicate
> Need UI mechanism to acquire version number of custom components
> ----------------------------------------------------------------
>
> Key: NIFI-666
> URL: https://issues.apache.org/jira/browse/NIFI-666
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework, Core UI, Documentation & Website,
> Extensions
> Reporter: Robert J. Mills
> Priority: Minor
>
> 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.
