  sources:
    - prometheus
    - datadog
    - cloudwatch
    - new_relic
    
  severity_levels:
    critical:
      response_time: 5_minutes
      channels: [pagerduty, slack_urgent, sms]
      escalation: immediate
      
    high:
      response_time: 15_minutes
      channels: [slack_alerts, email]
      escalation: after_15_minutes
      
    medium:
      response_time: 1_hour
      channels: [slack_alerts]
      
    low:
      response_time: 24_hours
      channels: [slack_logging]
      
  routing_rules:
    - if: service == "payments"
      team: payments_oncall
      severity_boost: +1
      
    - if: service == "auth"
      team: security_oncall
      
    - default:
      team: platform_oncall
