Single-node alert evaluation for high availability

UpdateUnverifiedAdded Sep 24, 2026

Grafana alerting has added single-node alert evaluation for high availability clusters. When enabled, only one Grafana instance in the HA cluster evaluates alert rules, reducing query load on data sources. Normally, when you run multiple instances of Grafana, all alert rules are evaluated on all instances by default.
