问题
I have written a PowerShell script to automate of download,install,configuration and start of AWS CloudWatch Agent on Windows EC2 Instance.
Right now I have a task to fetch Metrics of CloudWatch Agent such as %CPU Usage, %Memory Usage & %Disk Space usage of Windows EC2 Instance that would need to define on config.json which we configure using amazon-cloudwatch-agent-config-wizard.exe wizard.
Please help me to get %CPU usage, %Memory Usage and %Disk Space usage configure on cloudwatch custom metric for Windows EC2 Instance which need to configure for config.json file with AutoScalingGroupName already exists.
I don't want to do much complex thing, i just need config.json file with custom metric of %CPU usage, %Memory Usage and %Disk Space usage configure on cloudwatch custom metric for Windows EC2 Instance.
I have searched over search engine, unable to find out exact answer to help me configure for config.json file. I have searched for sample AWS CloudWatch Agent metric, unable to find config.json which give me %CPU Usage,%Memory Usage and %Disk Space Usage.

Kindly please help me to get custom metrics of CloudWatch Agent to present on config.json that will show %Usgae of CPU, %Usage of Memory and %Usgae of Disk Space for Windows EC2 Instance!
OS: Windows OS 64 bit
The script is working for Windows Server 2012, 2016 so far tested.
I will use same config.json file to configure custom cloudwatch agent metric.
