Triggers are events that cause a task to run. These include running tasks on a Schedule, when the system is Idle, when a change occurs on the file system, when a hotkey is pressed, when an entry is written to the system event log, when a certain error dialog appears on the screen, when certain performance thresholds are reached and much more. When a task is "triggered" the steps in the task (comprised of "actions") are executed.
Triggers are constructed in the Task Administrator in the Task Properties. To access trigger settings for tasks, open the Task Administrator, double click the task or select the task then select File | Properties.
When a task is triggered, it automatically creates a dataset called AMTrigger. This dataset can be used within a task to determine whether or not the task was started by a trigger, which trigger it was, and properties of that trigger. See Using AMTrigger for more information.
