Michael W Moser updated NIFI-16109:
-----------------------------------
    Description: 
When viewing the Summary page on the Connections tab, if a connection is 
configured with 0 back pressure object threshold and/or 0 back pressure size 
threshold, then the UI shows "undefined % | undefined %" in the "Threshold % : 
Queued %" column

!image-2026-07-13-12-20-33-418.png!

In the screenshot above, the top connection has 0 in back pressure object 
threshold and size threshold.  The bottom connection has 10,000 object 
threshold and 1 GB size threshold.
