Configuring a disk utilization threshold

To configure a disk threshold:

1. From the WhatsUp Gold web interface, go to Alert Center > Threshold Library. The Alert Center Threshold Library dialog appears.
2. Click New. The Select Threshold Type dialog appears.
3. Select Performance Disk, then click OK. The New/Edit Disk Utilization Threshold dialog appears.

   

4. Specify or select the appropriate information in the dialog boxes:
   • 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. Select and enter the desired threshold criteria variables and values. The default threshold triggers an alert when disk utilization exceeds 95% for more than 1 day. In addition to disk utilization, this threshold can also be configured to alert when free space exceeds or falls below a specific value.
   • 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.

   Note: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alert Center Home page.

   • Threshold check. Enter a value for the threshold check interval, or the interval at which the Alert Center checks the WhatsUp Gold database for items that are outside the threshold parameters.
   • Select Automatically resolve items no longer out of threshold to 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 adviced.

5. Click OK to save the threshold.
