By default, event monitoring is active 24 hours a day, 7 days a week. If you only want to monitor for an event at certain times, you can assign it a schedule. System-generated events cannot be placed on a schedule since they are always on.
Note: It is possible to disable a rule entirely by unchecking the On box in the Event Rules list.
