Configure a Network Traffic Analysis custom threshold:

  • Name. Used in the Threshold library and the quick select title on the Alert Center Dashboard.
  • Notification Policy. Select the notification policy to apply to this threshold. The policy initiates notifications when an item is outside the configured threshold limits.
  • Threshold Check Interval. Enter a time interval for Alert Center to check the WhatsUp Gold database for items that are out of the threshold limits.

    Automatically resolve items no longer out of threshold. Select this option if you want Alert Center to automatically resolve items when they return to the value within the threshold limit.

Tip: Notification policies are optional for most thresholds. Out of threshold items still appear on the Alert Center dashboard.

Add Condition Rules (chain together filters)

An example threshold involving multiple filters could state, "This threshold will alert when any host with Protocol matching TCP and Application matching pop3 sent or received more than 100 MB of data in the past 15 minutes."
