9-4-3 Modifying Time Parameters
Time parameters control the following characteristics:
Time Parameter Description
Interval Amount of time between each verification of a threshold status.
Trigger notice delay Amount of time that a threshold violation is maintained before triggering an alarm. By
default, an alarm is issued as soon as a condition is detected.
Normal notice delay After triggering an alarm, amount of time with no threshold violation before the alarm
status is removed from the threshold. By default, a normal notice is issued as soon as a
violation is no longer detected.
Follow the steps described below to modify any time parameters.
1. Open the Groups and Thresholds Configurations dialog box and click on the Thresholds tab to access the
corresponding tab page.

A threshold with these parameters verifies a threshold condition as per the specified monitoring interval. If the
condition is reached, and remains that way for a specified time (Trigger Notice Delay), an alarm is issued. After
the alarm is issued, if the condition returns to its normal state, and remains in that state for a specified time
(Normal Notice Delay), the threshold is reset to normal.
3. Select an interval from the Monitoring Interval box.
4. To activate a trigger notice delay, select the Trigger Notice Delay check box and select a delay time.
5. To activate a normal notice delay, select the Normal Notice Delay check box and select a delay time.
