> Automatic diagnostic at NiFi restart/stop
> -----------------------------------------
>
>                 Key: NIFI-8752
>                 URL: https://issues.apache.org/jira/browse/NIFI-8752
>             Project: Apache NiFi
>          Issue Type: Improvement
>            Reporter: Lehel Boér
>            Assignee: Lehel Boér
>            Priority: Major
>          Time Spent: 2h 50m
>  Remaining Estimate: 0h
>
> Each time NiFi is restarted/stopped we should automatically execute the 'diagnostic' command:
>  
> {code:java}
> bin/nifi.sh diagnostics <filename>
> {code}
> before actually restarting/stopping NiFi. This would help gathering useful information when NiFi is stopped/restarted because of some issues.
> The diagnostic should be configurable in the bootstrap configuration:
>  * turn on/off this feature (default would be on)
>  * path to the directory where files are stored
>  * maximum number of files we retain before deleting old files
>  * maximum size of the folder before deleting old files
