---------------------------------------
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.
