<a name="examples-cloudwatch"></a>

Amazon CloudWatch (CloudWatch) is a monitoring service for Amazon cloud resources and the applications you run on Amazon. You can use the following examples to program [CloudWatch](http://www.amazonaws.cn/cloudwatch) using the Amazon SDK for C\$1\$1.

Amazon CloudWatch monitors your Amazon resources and the applications you run on Amazon in real time. You can use CloudWatch to collect and track metrics, which are variables you can measure for your resources and applications. CloudWatch alarms send notifications or automatically make changes to the resources you are monitoring based on rules that you define.

For more information about CloudWatch, see the [Amazon CloudWatch User Guide](https://docs.amazonaws.cn/AmazonCloudWatch/latest/DeveloperGuide/).

**Note**  
Only the code that is necessary to demonstrate certain techniques is supplied in this Guide, but the [complete example code is available on GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/cpp). On GitHub you can download a single source file or you can clone the repository locally to get, build, and run all examples.
