Figure 59: New Configuration window for a CPU Utilization Rule
The fields displayed are defined as follows:
For a CPU Utilization event, the other parameters, such as the MIB variable, threshold, etc., are
predefined by the Extreme switch agent to be the following:
NOTE
To define an alarm for a CPU Utilization threshold event, select SNMP Trap as the Event Type, then select CPU
Utilization Rising Threshold or CPU Utilization Falling Threshold as the Event Name.
If you define an alarm for a CPU Utilization Rising Threshold event, an alarm is generated each time
the sample value meets the following conditions:
●
The sample value becomes greater than or equal to the Rising Threshold for the first time (including
the initial sample) after the alarm is enabled. (This is the startup condition.)
Rule Name For CPU Utilization, the name is predefined because there can only be one rule of this type
on a device.
Rising Threshold A threshold value, in percent, that triggers an event when the CPU utilization rises past this
value. This value is also used to compute a falling threshold, which is defined as 80% of
the rising threshold.
Description The description of the
extremeCpuUtilRisingThreshold
MIB variable.
MIB Variable The MIB variable is predefined to be
extremeCpuUtilRisingThreshold.0
.
Falling Threshold This is predefined as 80% of the rising threshold.
Sample Interval The sample interval for a CPU Utilization alarm is also predefined, and is set to 3 seconds.
Sample Type The sample value (a percentage) is always an absolute value.
Startup Alarm The Startup condition is predefined to be Rising.
