Configuring a Failover threshold
To configure a failover threshold:
- From the WhatsUp Gold web interface, go to Alert Center > Threshold Library. The Alert Center Threshold Library dialog appears.
- Click New. The Select Threshold Type dialog appears.
- Select Failover, then click OK. The New Failover Threshold dialog appears.
- Specify or select the appropriate information in the dialog box.
- 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 the desired threshold criteria variables and values. You can configure the threshold to alert you when any event occurs, when an error occurs, or when an informational event occurs. By default, the threshold is configured to alert you when any event has occurred in Failover.
- 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 to see if there are items that are outside the threshold parameters.
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 inadvisable. - Click OK to save the threshold.
