【问题描述】：
我编写了一个 PowerShell 脚本来自动下载、安装、配置和启动 Windows EC2 实例上的 AWS CloudWatch 代理。
现在我有一个任务来获取 CloudWatch 代理的指标，例如 Windows EC2 实例的 %CPU 使用率、% 内存使用率和 % 磁盘空间使用率，这需要在我们使用 amazon-cloudwatch 配置的 config.json 上进行定义- agent-config-wizard.exe 向导。
请帮助我在 cloudwatch 自定义指标上为 Windows EC2 实例配置 %CPU 使用率、% 内存使用率和 % 磁盘空间使用率，需要为 config.json 文件配置 AutoScalingGroupName 已经存在。
我不想做太多复杂的事情，我只需要在 Windows EC2 实例的 cloudwatch 自定义指标上配置 %CPU 使用率、% 内存使用率和 % 磁盘空间使用率的自定义指标的 config.json 文件。
我搜索了搜索引擎，无法找到帮助我配置 config.json 文件的确切答案。 我搜索了示例 AWS CloudWatch 代理指标，但无法找到 config.json，它为我提供了 %CPU 使用率、% 内存使用率和 % 磁盘空间使用率。

config.json 文件用于 Windows CloudWatch 代理的自定义指标需要配置。

请帮助我获取 CloudWatch 代理的自定义指标以显示在 config.json 上，这些指标将显示 Windows EC2 实例的 CPU 百分比、内存使用百分比和磁盘空间百分比！
操作系统：Windows 操作系统 64 位
到目前为止，该脚本适用于 Windows Server 2012、2016。
我将使用相同的 config.json 文件来配置自定义 cloudwatch 代理指标。
