Caution

This feature is available starting from MOS 21.1.

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 the OpenStack-related alerts. For other alerts, see Mirantis Container Cloud Operations Guide: Alert dependencies.

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.
