This reports the per-user global notification severity -- the severity tier reached when this specific resource user's or group's utilization crosses a global, systemwide, threshold defined for that resource pool. This sits conceptually between the fully local per-user threshold field and the fully aggregate resource-owner-level global severity, letting an admin see when one individual consumer's share alone is enough to breach a systemwide alerting bar. Per the MIB's own example, if total processor memory utilization exceeds the systemwide minor rising threshold specifically because of one heavy consumer, that consumer's entry in this field would reflect that minor severity attribution.
