    works great now on multiple differing flow.xml.gz's... I am thinking that 
perhaps we should include the min/max/avg flow files per queue as well just in 
case some users decides to set it to 1billion for a 60 byte file...

> 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.
