description: Route alerts, run on-call rotations, and drive incidents in Grafana IRM / OnCall — integrations (Alertmanager / Grafana Alerting / generic webhook / PagerDuty), Jinja2 routing + grouping templates, escalation chains (wait → notify schedule → notify team → webhook → auto-resolve), schedules (web + iCal + Terraform `grafana_oncall_schedule`), Slack chatops with Acknowledge/Resolve/Silence, and the P1-P4 incident lifecycle. Use when wiring Alertmanager to OnCall, deciding which team gets paged, building rotations from a Google Calendar / iCal, hooking up Slack notifications, or declaring an incident from an alert — even when the user says "page the platform team on critical alerts", "send Prometheus alerts to Slack", "set up our on-call rota", "escalation policy", or "auto-resolve when the alert clears" without naming OnCall / IRM. Heads up — OnCall OSS is in maintenance mode (archived March 2026); Grafana Cloud users should use IRM.

# Grafana OnCall & IRM
> **OnCall docs**: https://grafana.com/docs/oncall/latest/
> **IRM docs**: https://grafana.com/docs/grafana-cloud/alerting-and-irm/
> Grafana OnCall OSS is in maintenance mode (archived March 2026). Cloud users → **IRM**. Concepts (chains, schedules, integrations) are identical.
## Prerequisites
- Grafana Cloud stack with IRM/OnCall enabled
- API token (`Authorization: <token>`)
- Slack workspace + admin to install the OnCall app (for ChatOps)
## Core concepts
| Concept | Description |
|---------|-------------|
| **Integration** | Webhook URL accepting alerts; one per source |
| **Route** | Jinja2 condition that maps to an escalation chain (first True wins) |
