>                 Key: NIFI-6628
>                 URL:
>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Configuration
>            Reporter: Mark Payne
>            Priority: Major
> Currently, nifi has 3 logs that are generated: `nifi-app.log`, `nifi-user.log`, and `nifi-bootstrap.log`.
The vast majority of logs are written to `nifi-app.log`. This can result in the app log being
extremely verbose and difficult to follow if there are Processors that are configured with
an invalid username/password, etc. that result in spewing a lot of errors. As a result, it
can be very difficult to find error messages about framework/app itself.
> We should update the `logback.xml` file to add a new `nifi-framework.log` file that contains
framework-related loggers and let everything else go to `nifi-app.log`
