修改加速警示預設組態

雖然您無法修改預設組態設定檔，但您可以在自訂設定檔中使用與預設組態區塊相同的 ConfigurationID 來指定組態區塊，以提供預設值的覆寫。如果您這樣做，整個組態區塊會覆寫要套用標記組態的預設組態區塊。

例如，請考慮下列預設組態設定檔：

{
    "AWS::EC2::Instance": {
        "AMSManagedBlock1": {
            "Enabled": true,
            "Tag": {
                "Key": "ams:rt:ams-monitoring-policy",
                "Value": "ams-monitored"
            },
            "AlarmDefinition": {
                "AlarmName": "${EC2::InstanceId}: AMS Default Alarm",
                "Namespace": "AWS/EC2",
                "MetricName": "CPUUtilization",
                "Dimensions": [
                    {
                        "Name": "InstanceId",
                        "Value": "${EC2::InstanceId}"
                    }
                ],
                "Threshold": 5,
                ...
            }
        }
    }
}

若要將此警示的閾值變更為 10，您必須提供整個警示定義，而不只是要變更的部分。例如，您可以提供下列自訂設定檔：

{
    "AWS::EC2::Instance": {
        "AMSManagedBlock1": {
            "Enabled": true,
            "Tag": {
                "Key": "ams:rt:ams-monitoring-policy",
                "Value": "ams-monitored"
            },
            "AlarmDefinition": {
                "AlarmName": "${EC2::InstanceId}: AMS Default Alarm",
                "Namespace": "AWS/EC2",
                "MetricName": "CPUUtilization",
                "Dimensions": [
                    {
                        "Name": "InstanceId",
                        "Value": "${EC2::InstanceId}"
                    }
                ],
                "Threshold": 10,
                ...
            }
        }
    }
}
