在以下示例中，系统会为连接到匹配的 Linux 实例的每个磁盘创建警报。

```
{
    "AWS::EC2::Instance::Disk": {
        "LinuxDiskAlarm": {
            "Tag": {
                "Key": "ams:rt:mylinuxinstance",
                "Value": "true"
            },
            "AlarmDefinition": {
                "MetricName": "disk_used_percent",
                "Namespace": "CWAgent",
                "Dimensions": [
                    {
                        "Name": "InstanceId",
                        "Value": "${EC2::InstanceId}"
                    },
                    {
                        "Name": "device",
                        "Value": "${EC2::Disk::Device}"
                    },
                    {
                        "Name": "fstype",
                        "Value": "${EC2::Disk::FSType}"
                    },
                    {
                        "Name": "path",
                        "Value": "${EC2::Disk::Path}"
                    }
                ],
                "AlarmName": "${EC2::InstanceId}: Disk Usage Too High - ${EC2::Disk::UUID}"
                ...
            }
        }
    }
}
```

在以下示例中，系统会为连接到匹配的 Windows 实例的每个磁盘创建警报。

```
{
     "AWS::EC2::Instance::Disk": {
        "WindowsDiskAlarm": {
            "Tag": {
                "Key": "ams:rt:mywindowsinstance",
                "Value": "true"
            },
            "AlarmDefinition": {
                "MetricName": "LogicalDisk % Free Space",
                "Namespace": "CWAgent",
                "Dimensions": [
                    {
                        "Name": "InstanceId",
                        "Value": "${EC2::InstanceId}"
                    },
                    {
                        "Name": "objectname",
                        "Value": "LogicalDisk"
                    },
                    {
                        "Name": "instance",
                        "Value": "${EC2::Disk::Path}"
                    }
                ],
                "AlarmName": "${EC2::InstanceId}: Disk Usage Too High - ${EC2::Disk::UUID}"
                ...
            }
        }
    }
}
