The On-Call Paging Aggregation Policy

Multiple alerts in 5 minutes are usually one incident. The aggregation policy that prevents a 50-page incident.

The rule

Alerts within 5 minutes of each other for the same service: aggregated into one notification.

The aggregation has a list of contributing alerts. The on-call sees the full picture.

Scope

Per service. Cross-service alerts do not aggregate; they may be separate incidents.

Severity-aware: high-severity always pages even if it overlaps with a lower-severity aggregation.

Save

Typical incident: 10-30 alerts collapse to 1-3 notifications. Cognitive load drops.

Triage starts with the merged view. Faster comprehension.
