Because this data collection occurs at most once per day and you can configure it to run as infrequently as once per week, you may experience a significant delay before new alerts are generated with your new alert threshold. You canconfigure your wait monitoring using the Monitored SQL Server Properties window.

Apply different alert thresholds to multiple databases or disks

Some of the available alerts allow you to apply them independently to multiple databases or disks on your monitored SQL Server instance. When you click the alert to modify the thresholds, notice that a list of your databases or disks appears with the associated thresholds as they are currently set. Click Edit to make your changes. The Database Threshold Configuration dialog lets you specify the database, and then select the thresholds for that database only. The Disk Threshold Configuration dialog provides the same functionality, only disks replace the databases.

SQL Diagnostic Manager allows you to configure generic alert settings as a template that you can apply to servers and groups of servers in your organization. Click > Alert Configuration Templates and complete the required fields to configure an alert template.

Informational alerts

Informational alerts allow you to set a threshold that when generated triggers a status that does not affect the overall status of the server within SQL Diagnostic Manager. You can use informational alerts to notify an administrator of the state of a particular metric for a server or trigger secondary processes that could take action to prevent issue escalation.
