Module: USR-VHA-MIB
OID (symbolic): USR-VHA-MIB::usrVHAActiveSessionsCriticalAlarmThresh
OID (numeric): 1.3.6.1.4.1.429.4.84.10.2.1
Node type: OBJECT-TYPE

Access: read-only
Description: The critical alarm threshold for usrVHAActiveSessionsCurrent gauge. The allowed range of this object is 0 to usrVHAMaxSessions. If usrVHAMaxSessions is reduced below the value of this object, this object will automatically reduced so that this constraint holds. Object value of 0 disables this alarm and threshold.. IF this object is set to a non-zero value equal or less than the current value of usrVHAActiveSessionsMajorAlarmThresh, THEN usrVHAActiveSessionsMajorAlarmThresh will be automatically reduced to a valid value. IF this object is set to a non-zero value equal or less than the current value of usrVHAActiveSessionsClearAlarmThresh, THEN usrVHAActiveSessionsClearAlarmThresh will be automatically reduced to a valid value. This value is set indirectly by setting usrVHAActiveSessionsCriticalAlarmThreshPct Changing threshold values causes the alarm state to be re-evaluated. IF usrVHAActiveSessionsAlarmState is not 'critical' and the current gauge value is equal or greater than this critical threshold, and this critical threshold is non-zero, THEN usrVHAActiveSessionsAlarmState will change to 'critical'. See usrVHAActiveSessionsAlarmState for TRAP generation details.
What is usrVHAActiveSessionsCriticalAlarmThresh?
It is the critical alarm threshold for the usrVHAActiveSessionsCurrent gauge (active, non-dormant sessions), automatically capped at usrVHAMaxSessions and reducing the major/clear thresholds if needed to stay consistent. A value of 0 disables this alarm; otherwise, when active sessions reach or exceed it, usrVHAActiveSessionsAlarmState moves to 'critical', giving an admin a capacity warning specifically about actively transmitting sessions rather than the broader total.
