On-call schedules
Decide who gets paged, by rotation, and cover for people who are away.
1Add a schedule
Monitoring → Alerts → On-call → Add a schedule. Choose how long each turn lasts (a week or a day), when it hands over, the time zone, when the first turn starts, and who takes turns, in order.
2Page whoever is on call
Add an email or push notification destination (Monitoring → Alerts → Destinations) and choose the schedule as its recipient. Alerts then go to whoever is on call when they fire.
3Cover for someone
On the schedule, put someone else on call for a while, such as while the person whose turn it is is away. The schedule goes back to its rotation afterwards.
