> It is currently not possible to determine if a connection within a workflow is experiencing
backpressure. While metrics are provided in the ConnectionStatus object around objectsQueued
and bytesQueued this alone isn't enough to determine if any user defined backpressure is being
applied. The idea is to make that information about the backpressure available inside the
existing ConnectionStatus so that custom ReportingTasks can look for things like slow connections
and alert appropriately. 
> Mark Payne nifi dev list email excerpt - "It should be relatively easy. In FlowController,
we would have to update getGroupStatus() to set the values on ConnectionStatus
> and of course update ConnectionStatus to have getters & setters for the new values.
That should be about it, I think."
