Overview
The Scheduler decides who is on call at any given moment. Add a schedule as a target in an escalation policy, and Oppex pages whoever it resolves as on call the instant an incident fires — you never update a contact list by hand.
A schedule is made of one or more layers, each with its own rotation of people, its own timing, and its own rule for who counts as on call. The pages in this section walk through building one from scratch, in the order you'd normally set one up.
