Blackout Summary Threshold

From the WhatsUp Gold navigation menu:

1. Select SETTINGS menu > Alerts and Actions > Alert Center.

   Alert Center Libraries view displays.

2. Click Thresholds Library panel (to expand it if collapsed).

   The Thresholds Library displays.

3. On the Thresholds Library panel, click the "add" button ().

   The Select Threshold Type dialog displays.

4. Choose Blackout Summary Threshold and click OK. (This adds a new Blackout Summary Threshold to your library.)

   The New/Edit Blackout Summary Threshold Alert dialog displays. (Now, you must configure your Blackout Summary Threshold.)

5. Edit the Blackout Summary Threshold configuration.

To configure a Blackout Summary threshold:

1. Configure the following:
   • Name. Specify a name for the threshold. This name helps you identify the threshold in the Threshold library and displays as the report title on the Alert Center Home page.
   • Threshold. The threshold alerts you when a blackout period has ended and an action would have been triggered by a passive monitor or state change.

   Note: You cannot configure threshold criteria for the Blackout Summary threshold.

   • Devices to Monitor. Click Select to select the devices to which the threshold applies. By default, the threshold applies to all devices. Use this dialog to select groups to which this threshold does not apply.
   • Notification. Select the notification policy to apply to this threshold. This policy begins sending notifications when an item is outside the configured threshold limits. If you do not see an appropriate threshold policy, or if the list is empty, click browse (...) to open the Notification Policy dialog and configure a new policy.
   • Threshold check. Enter a time interval for Alert Center to check the Network Performance Monitor database for actions that were not triggered because of a scheduled blackout period that has finished.

   Note: Configure the threshold check interval for a longer time than the sampling interval for thresholds relating to trends, such as percent utilization. Configure it for a time the same as (or similar to) the sampling interval when configuring a threshold for a health check.
   Avoid setting the threshold check interval to a very short time, as this can degrade system performance. In general, setting the threshold check interval to less than five minutes is not advised.

2. Click OK to save the threshold settings.

Clone a threshold based on a custom or built-in configuration:

1. Click on a threshold on the Thresholds Library panel you want to copy.
2. Click the Copy button, and click OK to create a new Blackout Summary Threshold.

   The Edit Blackout Summary Threshold dialog displays.

3. Save or customize your new threshold, either:
   • Type in a new value for Name field (or keep the default) and click OK to save to the Thresholds Library.
   • Follow the Edit Blackout Summary Threshold instructions.

Delete an existing Blackout Summary Threshold:

1. Select Blackout Summary Threshold you want to delete from the Blackout Summary Threshold panel.
2. Click the Delete button, and then click Yes to confirm the deletion.

   The Blackout Summary Threshold configuration is deleted.
