Threshold. Select and enter the threshold criteria variables and values. You can
choose to create a threshold based on discards, errors, or a combination of the two.
The default threshold is configured to alert when inbound or outbound interface
utilization exceeds 100 discards per minute for more than 20 minutes.
- and / or -
when errors for inbound or outbound interface utilization exceeds 100 errors per
minute for more than 20 minutes.
Note: If you select both error and discard thresholds, each error and discard are reported as
separate items (rows) in the dashboard report.
Devices to Monitor. Click Select to choose the devices to which the threshold
applies. By default, the threshold monitors 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 to see if there are items
that are outside the threshold parameters. The default threshold check is 10 minutes.
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
inadvisable.
