pagerduty

Overview

Set up PagerDuty for incident management with on-call schedules, escalation policies, and integrations. Covers service creation, Events API for triggering alerts, schedule management, and automation via the REST API.

Best Practices

• Use dedup_key to prevent duplicate incidents for the same issue
• Set intelligent alert grouping to automatically correlate related alerts
• Include runbook links and dashboard URLs in alert custom details
• Configure support hours to route low-urgency alerts during business hours only
• Rotate on-call weekly and limit shifts to avoid burnout
• Use event orchestration to suppress noisy alerts and enrich events before routing
