Alert dependencies

Alert dependenciesΒΆ

Using alert inhibition rules, Alertmanager decreases alert noise by suppressing dependent alerts notifications to provide a clearer view on the cloud status and simplify troubleshooting. Alert inhibition rules are enabled by default.

The following table describes the dependency between alerts. Once an alert from the Alert column raises, the alert from the Silences column will be suppressed with the Inhibited status in the Alertmanager web UI.
