This carries the actual rising, or falling, threshold percentage value that was crossed to trigger this specific ERM violation notification. Including the actual threshold value in the trap itself, rather than requiring the receiver to look it up separately, means the notification is self-contained and can be logged or displayed with full context even if the receiving system has no live SNMP access back to the device. A trap reporting this field as 85 alongside a resource owner of io memory tells an admin, without any further polling, that 85 percent utilization is what specifically triggered this alert.
