 Use the **Adjust alert thresholds** page to customize the threshold level for specific alerts to influence their alert volume. For example, if you're running comprehensive testing, you might want to lower alert thresholds to trigger as many alerts as possible.
 
-Alerts are always triggered immediately if the **Recommended test mode** option is selected, or if a threshold level is set to **Medium** or **Low**, regardless of whether the alert's learning period has already completed.
