17.14 Scheduler triggers

Triggers attached to the scheduler follow the same basic rules and formats as attaching them to other objects; however, not all attribute options are valid for each object. The scheduler, like the other objects, has a unique set of trigger rules. The table below details the methods, options, and other notable details associated with attaching triggers to the scheduler.
