Memulihkan instans Amazon Elastic Compute Cloud

CloudWatch Alarm berikut memulihkan instans EC2 ketika mengalami kegagalan pemeriksaan status selama 15 menit berturut-turut. Untuk informasi selengkapnya tentang tindakan alarm, lihat Membuat alarm yang menghentikan, menghentikan, atau memulihkan instance di CloudWatch Panduan Pengguna Amazon.

Membuat dasbor dasar

Contoh berikut membuat CloudWatch dasbor sederhana dengan satu widget metrik yang menampilkan pemanfaatan CPU, dan satu widget teks menampilkan pesan.

JSON

{
    "BasicDashboard": {
        "Type": "AWS::CloudWatch::Dashboard",
        "Properties": {
            "DashboardName": "Dashboard1",
            "DashboardBody": "{\"widgets\":[{\"type\":\"metric\",\"x\":0,\"y\":0,\"width\":12,\"height\":6,\"properties\":{\"metrics\":[[\"AWS/EC2\",\"CPUUtilization\",\"InstanceId\",\"i-012345\"]],\"period\":300,\"stat\":\"Average\",\"region\":\"us-east-1\",\"title\":\"EC2 Instance CPU\"}},{\"type\":\"text\",\"x\":0,\"y\":7,\"width\":3,\"height\":3,\"properties\":{\"markdown\":\"Hello world\"}}]}"
        }
    }
}
    

YAML

BasicDashboard:
  Type: AWS::CloudWatch::Dashboard
  Properties:
    DashboardName: Dashboard1
    DashboardBody: '{"widgets":[{"type":"metric","x":0,"y":0,"width":12,"height":6,"properties":{"metrics":[["AWS/EC2","CPUUtilization","InstanceId","i-012345"]],"period":300,"stat":"Average","region":"us-east-1","title":"EC2 Instance CPU"}},{"type":"text","x":0,"y":7,"width":3,"height":3,"properties":{"markdown":"Hello world"}}]}'

Buat dasbor dengan side-by-side widget

Contoh berikut membuat dasbor dengan dua widget metrik yang muncul berdampingan.

    "DashboardSideBySide": {
        "Type": "AWS::CloudWatch::Dashboard",
        "Properties": {
