 When the conditions of a rule are met, it creates an alert. If the rule has actions, they run at the defined frequency. For example, the rule can send email notifications for each alert at a custom interval. For an introduction to the concepts of rules, alerts, and actions, refer to [Alerting](../alerts.md).
