What is atmSuSystemHistoryAlrStatus?

This OID records the status state of a historical alarm (such as active, cleared, or acknowledged) to track the lifecycle of past events. Network engineers use this to understand which alarms have been resolved or are still pending attention. For example, a status value of cleared shows that the alarm condition is no longer present on the system.
