[jira] [Commented] (NIFI-766) UI should indicate when backpressure is configured for a Connection
[ https://issues.apache.org/jira/browse/NIFI-766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=14629973#comment-14629973 ] Mark Payne commented on NIFI-766: - Dan, Hmmm. Interesting idea. I can totally picture what you're talking about. And I very much like it. There are two things that I think may be a concern with that approach though (i don't know if these are legitimate concerns or not, personally - would need someone else to evaluate): would the computation/rendering of that be expensive? We already render quite a lot and for large flows can push browsers to the brink. Also, would it end up making the UI more difficult to see/read or would it be distracting? I do really like the concept though of showing how full they are. Perhaps [~mcgilman] or someone who knows more about UI's can weigh in. And it may require trying it out to know for sure if the performance would suffer. But if neither of those things are concerning, then yes, I love it :) UI should indicate when backpressure is configured for a Connection --- Key: NIFI-766 URL: https://issues.apache.org/jira/browse/NIFI-766 Project: Apache NiFi Issue Type: Improvement Components: Core Framework, Core UI Reporter: Mark Payne Fix For: 0.3.0 It is sometimes unclear why a Processor is not running, if it is due to backpressure. Recommend we add an icon to the Connection label to indicate that backpressure is configured. If backpressure is applied (i.e., the backpressure threshold has been reached), that icon should be highlighted somehow. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

My only concern is whether it would make sense to the user. We could always use the same concept in a mini progress bar that's labeled accordingly. We also need to be mindful of other suggestions for changes on the connection label (NIFI-767). We are constantly fighting a battle between rendering important details and keeping the application usable. I think we are nearing the point where we may need to reconsider how and what's rendered there. I don't actually know what this means currently, but I know that we can't just keep adding to it.

What if the background of a connection label was filled (left-right) indicating how close it is to applying back pressure? e.g. Lets say Back pressure object threshold is set to 10 for a connection, and there were 3 objects in it then the left 3/10ths of the label could be shaded gray if there were 6 objects the left 6/10ths of the label could be shaded gray if there are 10 objects or more the whole label could be shaded a gray(or another color) or maybe have a warning/bulletin label attached to it indicating that back pressure happened. This might be better illustrated with pictures... If what I am describing isn't clear i'll try and gen up some PNGs UI should indicate when backpressure is configured for a Connection --- Key: NIFI-766 URL: https://issues.apache.org/jira/browse/NIFI-766 Project: Apache NiFi Issue Type: Improvement Components: Core Framework, Core UI Reporter: Mark Payne Fix For: 0.3.0 It is sometimes unclear why a Processor is not running, if it is due to backpressure.
