Introduction
Alert rule evaluation
Evaluation within a groupHow rules are evaluated within a group
Each evaluation group contains an evaluation interval that determines how frequently the rule is evaluated. For instance, the evaluation may occur every 10s, 30s, 1m, 10m, etc.
Rules in different evaluation groups can be evaluated simultaneously.
Rules within the same evaluation group can be evaluated simultaneously or sequentially, depending on the rule type:
Grafana-managed rules within the same group are evaluated concurrently—they are evaluated at different times over the same evaluation interval but display the same evaluation timestamp.
Data source-managed rules within the same group are evaluated sequentially, one after the other—this is useful to ensure that recording rules are evaluated before alert rules.
Grafana-managed rules imported from data source-managed rules are also evaluated sequentially.
