Amazon CloudWatch Command Line Interface Reference
AWS provides two sets of command line tools that each support CloudWatch. This section describes the CloudWatch command line interface (CLI). For more information about downloading and installing the CLI, see Set Up the Command Line Interface.
You can also use the AWS Command Line Interface to control and automate CloudWatch on Windows, Mac, and Linux. We also offer the AWS Tools for Windows PowerShell if you prefer to script in the PowerShell environment.
