Configure disk thresholds

The Disk Threshold Configuration dialog allows you to set alert thresholds for selected disks on your SQL Server instance. Not all alerts are available for applying disk-specific thresholds. The following alerts include disk-specific settings:

• OS Disk Free Space (Size)
• OS Disk Full (Percent)

Use the Advanced button to set how and when alerts are raised by limiting the number of alerts and notifications generated.

4. On the Configuration tab, click Add.
5. Select the disk from the available drop-down list.
