运行AWSFIS-Run-CPU-Stress报错：Windows EC2实例平台不匹配

错误原因很明确：你使用的AWSFIS-Run-CPU-Stress是Linux平台专用的SSM预定义文档，无法在Windows EC2实例上执行，因此触发平台不匹配报错。

解决方法是替换为Windows专属的SSM文档AWSFIS-Run-CPU-Stress-Windows，修改后的实验脚本如下：

{
  "description": "Test CPU stress predefined SSM document for Windows",
  "targets": {
    "testInstance": {
      "resourceType": "aws:ec2:instance",
      "resourceArns": ["arn:aws:ec2:region:123456789012:instance/instance_id"],
      "selectionMode": "ALL"
    }
  },
  "actions": {
    "runCpuStress": {
      "actionId": "aws:ssm:send-command",
      "parameters": {
        "documentArn": "arn:aws:ssm:region::document/AWSFIS-Run-CPU-Stress-Windows",
        "documentParameters": "{\"DurationSeconds\":\"120\"}",
        "duration": "PT5M"
      },
      "targets": {
        "Instances": "testInstance"
      }
    }
  },
  "stopConditions": [
    {
      "source": "aws:cloudwatch:alarm",
      "value": "arn:aws:cloudwatch:region:123456789012:alarm:awsec2-instance_id-GreaterThanOrEqualToThreshold-CPUUtilization"
    }
  ],
  "roleArn": "arn:aws:iam::123456789012:role/AllowFISSSMActions",
  "tags": {}
}

额外注意事项：

• 确认目标Windows实例已正确安装并运行SSM Agent，没有SSM Agent无法执行SSM命令
• 检查FIS角色AllowFISSSMActions的权限策略，确保它拥有执行AWSFIS-Run-CPU-Stress-Windows文档的权限
