Joseph Niemiec updated NIFI-3716:
---------------------------------
    Description: 
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.
