What Is an Inhibition Rule?

An inhibition rule mutes a set of alerts whenever a matching source alert is already active, on the assumption they share one cause. For example, a firing cluster-down alert can inhibit the dozens of per-service alerts that outage triggers. The inhibited alerts still exist but are held back from notification.

Why it matters

One failure often lights up many downstream alerts at once. Inhibition keeps responders focused on the originating problem instead of paging them for every symptom.
