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.
