This records the ITU perceived-severity level that was in effect for a specific alarm at the moment it was logged, based on the object's name and severity-typed syntax rather than its generic shipped description. Because severity on an active alarm can change over time via escalation timers, this log entry preserves what the severity actually was at logging time, giving a historical audit trail distinct from the live active-alarm severity value. For example, a log row showing major(3) for a link-down event that later escalated to critical(2) tells a reviewer the fault was already significant well before it became an outage-level page.
