Using durations for alerts is a great way to reduce the total number of alerts you receive. There are times when you want an alert to trigger as soon as the condition is detected. Other times, you may only want the alert to trigger when a condition exists for more than a certain amount of time.

For example, the WAN link out of your corporate headquarters might occasionally spike over 80% utilization. However, you only want to be alerted if the link is more than 80% for longer than 10 minutes. Set conditions to receive an alert when the utilization on the WAN link is over 80% for 10 minutes, and you will only receive an alert when there is a sustained spike.

The following example illustrates an alert that includes duration. Ensure that you select the Condition must exist check box and enter a duration.
