Custom 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 Custom Threshold and click OK. (This adds a new Custom Threshold to your library.)

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

5. Edit the Custom Threshold configuration.

To configure a custom performance monitor 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.
   • Show. Select either Global Monitors or Device Specific Monitors for the custom performance monitor type that you choose.
   • Custom performance monitor type. Select the custom performance monitor type from the menu. Select APC UPS, Printer, Active Script, SNMP, or WMI.
   • Monitor. The configured monitors of the selected type. These are the monitors used to determine if the measured parameters have dropped below or exceeded threshold limits.

   Note: When you select Global Monitors, this list is populated with custom performance monitors currently configured in the Monitor Library. When you select Device Specific Monitors, this list is populated with custom performance monitors currently configured for specific devices.

   • Threshold. Select and enter the desired threshold criteria variables and values. The default threshold is configured to alert when the custom performance monitor average value exceeds 10 for 30 minutes.
   • Devices to Monitor. Click Select to choose the devices to which the threshold applies. By default, the threshold applies to all devices where the applicable monitor is enabled.
   • 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.

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

   • Threshold Check. Enter a value for the threshold check interval, or the interval at which the Alert Center checks the WhatsUp Gold database to see if there are items that are outside the threshold parameters.
   • Select Automatically resolve items no longer out of threshold to have Alert Center automatically resolve items when they go back inside the parameters of the threshold.

   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 Custom Threshold.

   The Edit Custom 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 Custom Threshold instructions.

Delete an existing Custom Threshold:

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

   The Custom Threshold configuration is deleted.
