             Summary: Detailed dataflow statistics/info needed for back pressure and expiration.
                 Key: NIFI-314
                 URL: https://issues.apache.org/jira/browse/NIFI-314
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core Framework
            Reporter: Matthew Clarke


Currently connections that have "File Expiration" set show this information through an icon displayed on the connection box on the graph.  This icon should be expanded to show what back pressure object and back pressure data size thresholds have been set. 

There are two pieces to this expanded information that are missing that would make this information more useful to the end user.
1. There should be some indication to the end user when one of the above set values is occurring.   (Are files actually expiring?  Is back pressure currently being applied?)
2. Expose this information in the summary table connections tab. While it is great that this information is exposed on the graph. On large dataflows it can be hard to find or go unnoticed.  The summary table serves as a great resources for identifying where issues exist within the dataflow.  Bulletins displayed on the graph also show here.  end users need to be able to find/identify from the summary table when things like file expiration and back pressure are occurring.
