Alerting Layer Alerts are routed through a dedicated alerting service (PagerDuty, Opsgenie, or equivalent) that ensures delivery, tracks acknowledgement, and escalates unacknowledged alerts according to the escalation framework. The alerting service must guarantee delivery; an alert that is generated but not delivered is worse than no alert, because it creates a false sense that the monitoring system is working. Alert fatigue is a serious operational risk. Too many low-value alerts cause operators to ignore the alerting system entirely, including the high-value alerts. Threshold tuning and alert suppression for known, documented conditions are essential. The PMM plan documents the suppression rules and the rationale for each, ensuring that suppression does not mask genuine compliance issues. Each alert carries metadata linking it to the relevant AISDP module, the compliance obligation it relates to, and the severity tier. This metadata enables compliance-focused triage and reporting. Key outputs

• Dedicated alerting service with guaranteed delivery
• Alert fatigue mitigation through threshold tuning and suppression
• Per-alert metadata (AISDP module, compliance obligation, severity)
• Suppression rules documented with rationale
