Eventi di allarme e EventBridge
CloudWatch invia eventi ad Amazon EventBridge ogni volta che un CloudWatch allarme viene creato, aggiornato, eliminato o cambia lo stato dell'allarme. Puoi utilizzare EventBridge questi eventi per scrivere regole che intraprendano azioni, come avvisarti quando un allarme cambia stato. Per ulteriori informazioni, consulta What is Amazon EventBridge?
CloudWatch garantisce la trasmissione degli eventi di modifica dello stato di allarme a EventBridge.
