Grafana Cloud IRM provides an integrated solution for on-call management and incident response, which can be connected to self-hosted versions of Grafana OSS or Enterprise using a webhook integration. This connection allows users to utilize Grafana Cloud IRM's features, such as on-call scheduling, escalation chains, and incident tracking, without needing to fully migrate to Grafana Cloud. The system supports routing alerts based on custom policies and distinguishes between important and default notifications to tailor responses. Heartbeat monitoring ensures the reliability of the alert-to-incident pipeline by automatically creating incidents if expected alerts are not received within a set timeframe. Users are encouraged to configure their alert rules to ensure only critical alerts trigger a response, and they can take advantage of the free-tier plan in Grafana Cloud to explore these features.
