to control the type of notification you want. See the steps outlined in
RMON Events.
10. Click in the Rising Threshold field and enter the high threshold for the
sampled statistic. A single alarm is generated for the object if either of the
following conditions is met:
• The current sampled value is greater than or equal to this threshold
and the value at the last sampling interval was less than this
threshold.
• The first sample after this entry becomes valid is greater than or
equal to this threshold and the associated Startup Alarm is equal to
Rising_or_Falling or Rising.
After a rising alarm is generated, another rising alarm will not be
generated until the sampled value falls below the Rising Threshold and
reaches the Falling Threshold.
11. Click in the Rising Event Index field and enter the index of the Rising
Threshold Event definition. This is the event in the Event Table which
will be generated when this Rising Threshold Alarm is triggered. Use this
to control the type of notification you want. See the steps outlined in
RMON Events.
12. Enter the Rate and Sample Type in the Sampling Information box.
• Rate—The interval in seconds over which data is sampled and
compared with the rising and falling thresholds.
• Sample Type—The method of sampling the selected variable. Choices
are:
- Absolute—The value of the selected variable is compared directly
with the thresholds at the end of the sampling interval.
- Delta—The value of the selected variable at the last sample is
subtracted from the current value and the difference compared
with the thresholds.
13. To complete the process, click the right mouse button, or select Save All
Changes from the File menu, and click OK in the dialog box that appears.
At this point you should see the Status button change to underCreation.
14. Close the window and return to the Alarm Table View.
NOTE
If you want to modify your selections, you can reenter the information as long
as the Status button indicates the alarm is underCreation. Do not modify your
entry for the Index field in an attempt to create another alarm. Close the
window and select New Alarm if you want to create another alarm.
