How to: Add a Threshold Rule
Threshold rules in load tests compare a performance counter value with either a constant value or another performance counter value.
Adding a Threshold Rule
To add a threshold rule
Open a load test.
In the Load Test Editor, expand the Counter Sets node.
Expand one of the Counter Categories in one of the Counter Sets. For example, you can select LoadTest:Scenario. Expand the node.
Right-click one of the counters, for example, User Load, under LoadTest:Scenario. Select Add Threshold Rule.
The Add Threshold Rule dialog box is displayed.
You can choose from two types of rules: Compare Constant and Compare Counter. Select the appropriate type and set the values.
Set the Alert If Over property to True to indicate that exceeding a threshold is a problem. Set the Alert If Over property to False to indicate that falling below a threshold is a problem.
