問題文
The store's cluster becomes entirely unreachable. An alert for the whole cluster fires, and so do dozens of alerts for individual services inside it. The team wants only the cluster-level page. Which feature is designed for this?
選択肢
- Grouping, configured so that all the service-level alerts and their label sets are collapsed into the cluster-level notification.
- The keep_firing_for clause on the cluster-level rule, which suppresses the notifications of the other rules for the duration it specifies.
- Silencing, applied to the service-level alerts in Alertmanager with an expiry that matches the outage duration.
- Inhibition, configured so that the cluster-level alert mutes the notifications of the service-level alerts while it is firing.
