为CloudWatch EC2实例配置AWS EC2代理的自定义度量[%CPU、%内存、%DiskSpace]

Question

我编写了一个PowerShell脚本，用于自动下载、安装、配置和启动CloudWatch EC2实例上的AWS代理。

现在，我有一个任务要获取CloudWatch代理的度量，如%CPU使用率、%内存使用率和% EC2实例磁盘空间使用率，这将需要在config.json上定义，我们使用Agent -config-wizard.exe向导进行配置。

请帮助我获得%CPU使用率，%内存使用率和%磁盘空间使用配置的云观看自定义度量的Windows EC2实例，需要配置config.json文件与AutoScalingGroupName已经存在。

我不想做太多复杂的事情，我只需要config.json文件，它的自定义度量为%CPU使用率、%内存使用率和%磁盘空间使用配置，用于EC2实例的cloudwatch自定义度量。

我已经搜索过搜索引擎，无法找到准确的答案来帮助我配置config.json文件。我搜索了示例AWS CloudWatch代理度量，找不到config.json，它给了我%CPU使用率、%内存使用率和%磁盘空间使用率。

用于自定义度量的config.json CloudWatch代理需要配置。

请帮助我获得CloudWatch代理的自定义度量标准，以便在config.json上显示CPU的%Usgae、内存的使用%和EC2实例磁盘空间的%Usgae！

操作系统: Windows OS 64位

到目前为止，该脚本正在为Windows 2012、2016进行测试。

我将使用相同的config.json文件来配置自定义的cloudwatch代理度量。

使用这些AWS博士验证配置了所有正确的权限。很可能您只是缺少正确的IAM权限。

要进一步排除故障，可以通过在“度量”之前添加以下部分(确保更新区域)来启用调试：{：

"agent":  {
              "metrics_collection_interval":  60,
              "region":  "us-east-1",
              "logfile":  "c:\\ProgramData\\Amazon\\CloudWatchAgent\\Logs\\amazon-cloudwatch-agent.log",
              "debug":  true,
              "run_as_user":  "cwagent"
          },
 "metrics": {
              ...

在添加了这个之后，用config.json重新导入.\amazon-cloudwatch-agent-ctl.ps1 -a fetch-config -m ec2 -c file:'C:\Program Files\Amazon\AmazonCloudWatchAgent\config.json' -s。
