Amazon CloudWatch-Vorlagenausschnitte

Verwenden Sie diese Beispielvorlagen, um Ihre Amazon CloudWatch-Ressourcen in CloudFormationzu beschreiben. Weitere Informationen finden Sie in der Amazon CloudWatch Ressourcentyp-Referenz.

Fakturierungsbenachrichtigung

Im folgenden Beispiel, sendet Amazon CloudWatch eine E-Mail-Benachrichtigung, wenn die Gebühren Ihres AWS-Kontos den Alarm-Schwellenwert übersteigen. Um Nutzungsbenachrichtigungen zu erhalten, aktivieren Sie Fakturierungsbenachrichtigungen. Weitere Informationen finden Sie unter Erstellen eines Abrechnungsalarms zur Überwachung Ihrer geschätzten AWS Gebühren im Amazon CloudWatch Benutzerhandbuch.>

CPU-Nutzungsalarm

Der folgenden Beispiel-Ausschnitt erstellt einen Alarm, der eine Benachrichtigung versendet, wenn die durchschnittliche CPU-Auslastung einer Amazon EC2-Instance 90 Prozent länger als 60 Sekunden überschreitet und das über drei Bewertungszeiträume.

"CPUAlarm" : {

Wiederherstellung einer Amazon Elastic Compute Cloud-Instance

Der folgenden CloudWatch-Alarm stellt eine EC2-Instance wieder her, wenn für 15 aufeinanderfolgende Minuten Störungen der Statusprüfung aufgetreten sind. Weitere Informationen zu Alarmaktionen finden Sie unter Erstellen von Alarmen zum Anhalten, Beenden, Neustarten oder Wiederherstellen einer EC2-Instance im Amazon CloudWatch Benutzerhandbuch.

Erstellen eines grundlegenden Dashboards

Das folgende Beispiel erstellt ein einfaches CloudWatch-Dashboard mit einem Metrik-Widget, das die CPU-Auslastung anzeigt, und einem Text-Widget, das eine Nachricht anzeigt.

{
    "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\"}}]}"
        }
    }
}
    

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"}}]}'

Erstellen eines Dashboards mit Side-by-Side-Widgets

Im folgenden Beispiel wird ein Dashboard mit zwei Metrik-Widgets erstellt, die nebeneinander angezeigt werden.

{
    "DashboardSideBySide": {
        "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\":\"metric\",\"x\":12,\"y\":0,\"width\":12,\"height\":6,\"properties\":{\"metrics\":[[\"AWS/S3\",\"BucketSizeBytes\",\"BucketName\",\"amzn-s3-demo-bucket\"]],\"period\":86400,\"stat\":\"Maximum\",\"region\":\"us-east-1\",\"title\":\"amzn-s3-demo-bucket bytes\"}}]}"
        }
    }
}
