修改加速警报默认配置

虽然您无法修改默认配置文件，但您可以通过在自定义配置文件中指定与默认配置块相同的 ConfigurationI d 的配置块来覆盖默认配置文件。如果这样做，则整个配置块将覆盖要应用标签配置的默认配置块。

例如，考虑以下默认配置文件：

{
    "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,
                ...
            }
        }
    }
}

要将此警报的阈值更改为 10，您必须提供完整的警报定义，而不仅仅是要更改的部分。例如，您可以提供以下自定义配置文件：

{
    "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,
                ...
            }
        }
    }
}
