             Summary: Improve visual indicator of which node(s) have reached the backpressure limit in a NiFi cluster
                 Key: NIFI-10825
                 URL: https://issues.apache.org/jira/browse/NIFI-10825
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Ryan Hendrickson


In a NiFi Cluster with backpressure set to 20,000 the queue and the queue showing 75,000 items in it, the visual indicator reports RED and hovering states: "Queue: 100% full (based on 20000 object threshold).
 
What's misleading about this statement is that the cluster itself is not 100% full at that relationship, one or more nodes are 100% full at that relationship.
 
It'd be great to see the hover improved to show a bar indicator of each node in the cluster and how far full it is, or show a simple table in the hover with the node hostname and the queue size % on that host. For example:
    node 1 : 50%
    node 2: 100%
    node 3: 100%
    node 4: 80%
    node 5: 10%
 
Then we'd know much quicker which nodes are loaded at that point and it would be much more obvious to a nifi layman that only a portion of the cluster has backpressure engaged.
