80% CPU threshold alarms on Force 10 device even though CA Spectrum CPU threshold set to 85%
Environment
Component:
Cause
The CPU threshold alarm is from the device chAlarmExdCpuThreshold trap mapped in the $SPECROOT/SS/CsVendor/Force10/AlertMap file NOT from the Spectrum CPU threshold functionality configured in the Thresholds and Watches -> Thresholds subview in the Information tab of the model.
The out of the box device CPU thresholding functionality generates the 0x10f03 event when the CPU threshold is exceeded.
Major Dec 12, 2014 2:00:38 PM EST <Device Name> High CPU Utilization. The utilization of 88% for CPU instance 2 named 'CPU: 2' has exceeded the 80% threshold on model <Device Name> for more than the acceptable time period. System 0x10f03
The chAlarmExdCpuThreshold trap generates event 0x5bc0026:
Nov 24, 2014 9:00:55 PM EST fs0515-804 "A ""chAlarmExdCpuThreshold"" event has occurred, from Force10SwRtr device, named <Device Name>
The CPU utilization has exceeded 80%.
chAlarmVarInteger = 4
chAlarmVarString = CPU_THRESHOLD: Overall cp cpu usage above threshold.

The following is the $SPECROOT/SS/CsVendor/Force10/AlertMap file configuration for the chAlarmExdCpuThreshold trap:
# chAlarmExdCpuThreshold chAlarmVarInteger
1.3.6.1.4.1.6027.3.1.1.4.0.37 0x05bc0026 1.3.6.1.4.1.6027.3.1.1.4.1.1(1,0)\

# chAlarmVarPort
1.3.6.1.4.1.6027.3.1.1.4.1.4(4,0)
The following is the $SPECROOT/SS/CsVendor/Force10/EventDisp file configuration for the 0x05bc0026 event:
0x05bc0026 E 20 A 2,0x05bc0026,3,4
