Caution

As of 2026-03-24, the Grafana OnCall OSS project is archived. The grafana/oncall repository is read-only, and active development continues in Grafana Cloud IRM. For a fully supported and actively maintained alternative, Grafana Cloud IRM offers a modern approach to incident response and on-call management.

Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.
