Track devices experiencing failed, incomplete, or malformed connections.

Managing Failed Connections:
From the Thresholds Library in the WhatsUp Gold Alert Center Libraries view, you can perform the following Failed Connections operations.
Add. Create a new Failed Connections.
From the WhatsUp Gold navigation menu:
Alert Center Libraries view displays.
The Failed Connections displays.
The Select Failed Connections Type dialog displays.
The Configure Threshold Alert dialog displays.
Edit. Adjust, tune, and configure an existing Failed Connections.
Track devices experiencing failed, incomplete, or malformed connections. See port scanning, probing, and DoS attacks.
Configure a Network Traffic Analysis failed connections threshold:
Automatically resolve items no longer out of threshold. Select this option if you want Alert Center to automatically resolve items when they return to the value within the threshold limit
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.
Add Condition Rules
Note: Sources sending sampled data are not displayed as a selection option in the Traffic to monitor list because Network Traffic Analysis cannot determine that traffic has failed on sampled data.
Tip: When you select a source, traffic for all interfaces on the source is monitored. When you select an interface, only traffic for the selected interface is monitored.
Exclude Hosts. Select to ignore the traffic for a list of hosts you assemble here.
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.
Tip: Avoid setting the threshold check interval to a very short time. Aggressive intervals can degrade system performance. In general, setting the threshold check interval to less than five minutes is not advised.
Copy. Clone a new Failed Connections based on an existing Failed Connection configuration.
Clone a threshold based on a custom or built-in configuration:
The Edit Failed Connections dialog displays.
Delete. Remove Failed Connections from library.
Delete an existing Failed Connections:
The Failed Connections configuration is deleted.
