If you click the Schedule tab on the top navigation bar, the Schedule category and links appear. These pages enable you to track the actions taking place within your systems. An action is a scheduled RHN task that is to be performed on one or more client systems. For example, an action can be scheduled to apply all Errata Updates to a system.

Rollback Package Actions
System Reboots
Errata Updates
Configuration File Alteration (deploy, upload, and diff)

Each page in the Schedule category represents an action status.
