Once tests have been provisioned, you can specify threshold values for specific time windows. This allows setting alarm thresholds that match varying patterns of use or load in the IT infrastructure. For example, if nightly back-up jobs increase the utilization levels of a server during the evening hours, then you can set higher threshold levels for this time period so that unnecessary alarms are not generated. The day time thresholds can be set to be lower to ensure that a quality end-user experience is provided.
Setting Time Based Thresholds for One or More Tests
Select the Administration tab.
On the Manage Devices page, for a given device click the Tests link.

Check the Adaptive Threshold check-box. A Configure link displays when you do.
Click the Configure link. An Edit Time-Based Thresholds window displays.
Specify warning and critical threshold values for hourly ranges for each weekday. Each time you specify an hourly range for a weekday, the "hours outstanding" range is added below it, until all the hours of the day are accounted for.
After you have filled out the grid of threshold values, click the Apply button.
