Transcoding Capacity Traps

The Oracle® Enterprise Session Border Controller sends the apSysMgmtGroupTrap as transcoding capacity nears its limit. This trap is sent and cleared for three conditions:

  • Total DSP usage exceeds 95%
  • Total AMR sessions exceed 95% of provisioned capacity
  • Total AMR-WB sessions exceed 95% of provisioned capacity
  • Total EVRC sessions exceed 95% of provisioned capacity
  • Total EVRCB sessions exceed 95% of provisioned capacity

The apSysMgmtGroupTrap contains the condition observed (apSysMgmtTrapType) and the corresponding value reached (apSysMgmtTrapValue). 

apSysMgmtGroupTrap 		NOTIFICATION-TYPE
	OBJECTS		{ apSysMgmtTrapType, apSysMgmtTrapValue }
	STATUS	   	current
	DESCRIPTION
	      " The trap will generated if value of the monitoring object
	      exceeds a certain threshold. "
	::= { apSystemManagementNotifications 1 }

When the resource usage retreats below a defined threshold, the Oracle® Enterprise Session Border Controller sends an apSysMgmtGroupClearTrap. 

apSysMgmtGroupClearTrap		 NOTIFICATION-TYPE
	OBJECTS		{ apSysMgmtTrapType }
	STATUS	   	current
	DESCRIPTION
	      " The trap will generated if value of the monitoring object
	      returns to within a certain threshold.  This signifies that
	      an alarm caused by that monitoring object has been cleared. "
	::= { apSystemManagementNotifications 2 }

The following table summarizes trigger and clear conditions for transcoding capacity alerts as sent in the the apSysMgmtGroupTrap:

The following SNMP Objects are inserted into the apSysMgmtTrapType when sending and clearing a transcoding capacity trap. You mayt query them individually with an SNMP GET.

  • apSysXCodeCapacity (1.3.6.1.4.1.9148.3.2.1.1.34)
  • apSysXCodeAMRCapacity (1.3.6.1.4.1.9148.3.2.1.1.35)
  • apSysXCodeAMRWBCapacity (1.3.6.1.4.1.9148.3.2.1.1.36)
  • apSysXCodeEVRCCapacity (1.3.6.1.4.1.9148.3.2.1.1.39)
  • apSysXCodeEVRCBCapacity(1.3.6.1.4.1.9148.3.2.1.1.40)
