Hi gengz, di tutorial kali ini kita akan coba untuk instalasi cloudwatch untuk EC2, support monitor memory juga loh. Yuk kita coba aja.

Requirement : EC2 sudah terbuat dan sudah bisa diremote via ssh

Kita mulai dengan membuat IAM Roles dulu ya. Silahkan akses url berikut https://console.aws.amazon.com/iam/. Lalu masuk ke Roles
