Build on-call schedules and rotations so the right person gets woken up at 3 AM - not everyone. Set overrides for holidays and hand-offs. Your team stays sane, and incidents still get handled.
Incident fires -> on-call roster consulted -> escalation chain paged until ACKed -> incident closed.
Build weekly, bi-weekly, or custom rotation schedules. Everyone takes their fair share. The schedule is always visible so your team knows exactly who's on call and when their turn comes around. Multiple schedules for different teams or services.
People take holidays. People get sick. People swap shifts because they have a dentist appointment on Tuesday. Overrides let you handle all of it without breaking the underlying rotation. One-time overrides for specific date ranges, and the original schedule stays intact.
If the on-call engineer doesn't respond in 5 minutes, escalate to the next person. Then the next. Different channels at each step - SMS first, then phone call. Every incident gets handled, even if someone's phone is on silent or they slept through the notification. Acknowledge to stop escalation, or let it keep climbing.
Install one agent. Get security monitoring, infrastructure alerts, and on-call management - all included, every plan.
