>                 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.
