The Disk Notification notifies you of the total disk usage by Logpoint file systems. When there is a new notification, the navigation bar displays an alert. Click the Notification icon to open Notification Center.
Disk Notification¶
Notifications have one of two severity levels:
Notification with critical severity when the disk usage reaches 80% of its allocated space.
Notification with alert severity when the disk usage reaches 90% of its allocated space.
A Logpoint administrator can configure these values to generate notifications at any threshold. Similarly, manually configured notifications also do not include severity.
Note
If you configured disk notification before upgrading to Logpoint v6.8.0, Logpoint adds and generates the default two severity level notifications. Pre-existing notifications and notifications configured prior to Logpoint v6.8.0 do not include severity level.
The Disk, CPU, and Memory Notifications use a common SSH Certificate.
