Introducing Signal: On-Call Alerting System

Introducing Signal 🚨

• Signal is our new on-call paging and alerting system. Create schedules, define escalation paths, and trigger alerts via Rules or manual page.
• Schedules: Define who is on call and when.
• Escalation Policies: Set time-based escalation if the on-call person doesn't respond.
• Pages: Trigger an alert manually or via automation that contacts the on-call user(s) by SMS, call, or push notification.
• Signal helps teams respond faster to urgent issues and ensures coverage around the clock.
