An alert rule is a set of evaluation criteria that determines whether an alert will fire. The alert rule consists of one or more queries and expressions, a condition, the frequency of evaluation, and optionally, the duration over which the condition is met.
While queries and expressions select the data set to evaluate, a condition sets the threshold that an alert must meet or exceed to create an alert. An interval specifies how frequently an alert rule is evaluated. Duration, when configured, indicates how long a condition must be met. Alert rules can also define alerting behavior in the absence of data.
Note
Grafana managed alert rules can only be edited or deleted by users with Edit permissions for the folder storing the rules.
Alert rules for an external Grafana Mimir or Loki instance can be edited or deleted by users with Editor or Admin roles.
