Tests passed but still null. Attached my flow.xml.gz for you to work with.
Also RAT went off about unlisc files :)
```

> Utility to calculate MAX storage required for BackPressure on a Node

> Key: NIFI-3716
> URL: https://issues.apache.org/jira/browse/NIFI-3716
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joseph Niemiec
> Assignee: Eric Ulicny
> Priority: Trivial
>
> Today there is no way to understand the max amount of data which can be
> stored in backpressure for a given flow. Personally have had users configure
> queues with impossible backpressure amounts that would definitely fill the
> disk, having an operational tool to understand if anyone has done something
> so dramatic would be helpful.
> I see this produce a report by analyzing the FlowFile.xml.gz.
> * Total Storage for all queues Backpressure
> * Average Storage of all queues Backpressure
> * Min and Max of all queues Backpressure over the entire flow.
