Event Configuration
below theFalling threshold. Atpoint Bthe value againpasses theRising Threshold,but no
alarm is generated because the value has not yet become less than the Falling threshold.
Another Rising threshold alarm cannot occur until after a Falling threshold event has
occurred, which happens at point Y. The next Rising threshold event happens at point C.
Note that in order to have any of these events cause an alarm in the EPICenter Alarm
System, you need to define an alarm that responds to a CPU Utilization Rising Threshold
or CPU Utilization Falling Threshold event.
• If you define an alarm based on the CPU Utilization Rising Threshold event, an
EPICenter alarm will occur at the initial sample, and at points A and C. Because the
alarm was defined to respond to CPU Utilization Rising Threshold events, the falling
threshold trap events that occur at points X and Y do not trigger an EPICenter alarm.
• If you also define an alarm based on a CPU Utilization Falling Threshold event, then
EPICenter alarms would be generated at points X and Y.
