Question

我已经编写了一个PowerShell脚本来自动执行Windows EC2实例上的AWS CloudWatch Agent的下载，安装，配置和启动。

现在，我有一项任务需要获取CloudWatch Agent的指标，例如Windows EC2实例的％CPU使用率，％内存使用率和％Disk空间使用率，这些需要在config.json上定义，我们使用amazon-cloudwatch- agent-config-wizard.exe向导。

请帮助我获取在Windows EC2实例的cloudwatch自定义指标上配置的％CPU使用率，％内存使用率和％Disk空间使用率，它们需要使用AutoScalingGroupName配置config.json文件。

我不想做很多复杂的事情，我只需要配置具有％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，即可在Windows EC2实例的cloudwatch自定义指标上进行配置。

我在搜索引擎中进行了搜索，无法找到确切的答案来帮助我配置config.json文件。我已经搜索了示例AWS CloudWatch Agent指标，无法找到config.json，它给出了％CPU使用率，％内存使用率和％磁盘空间使用率。

用于自定义指标的Windows CloudWatch Agent的

config.json文件需要配置。

请帮助我获取CloudWatch代理的自定义指标以显示在config.json上，该指标将显示Windows EC2实例的CPU使用率，内存使用率和磁盘空间使用率！

OS：Windows OS 64位

该脚本目前可用于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。

使用这些 AWS docs验证您是否配置了所有正确的权限。您可能只是缺少正确的IAM权限。

要进行进一步的故障排除，您可以通过在“指标”之前添加以下部分（确保更新区域）来启用调试功能：{：

"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": {
              ...

添加此内容后，请用.\amazon-cloudwatch-agent-ctl.ps1 -a fetch-config -m ec2 -c file:'C:\Program Files\Amazon\AmazonCloudWatchAgent\config.json' -s

重新导入您的config.json。

检查以下位置的日志：

C：\ ProgramData \ Amazon \ CloudWatchAgent \ Logs
C：\ ProgramData \ Amazon \ AmazonCloudWatchAgent \ Logs

为Windows EC2实例配置AWS CloudWatch Agent的自定义指标[％CPU，％Memory，％DiskSpace]
