Acara alarm dan EventBridge
CloudWatch mengirimkan peristiwa ke Amazon EventBridge setiap kali CloudWatch alarm dibuat, diperbarui, dihapus, atau mengubah status alarm. Anda dapat menggunakan EventBridge dan peristiwa ini untuk menulis aturan yang mengambil tindakan, seperti memberi tahu Anda, ketika alarm berubah status. Untuk informasi selengkapnya, lihat Apa itu Amazon EventBridge?
CloudWatch menjamin pengiriman peristiwa perubahan status alarm ke EventBridge.
Contoh peristiwa dari CloudWatch
Bagian ini mencakup contoh peristiwa dari CloudWatch.
