-// Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the
-// applications you run on AWS in real-time. You can use CloudWatch to collect
-// and track metrics, which are the variables you want to measure for your resources
-// and applications.
+// CloudWatch provides the API operation methods for making requests to
+// Amazon CloudWatch. See this package's package overview docs
+// for details on the service.
 //
-// CloudWatch alarms send notifications or automatically make changes to the
-// resources you are monitoring based on rules that you define. For example,
-// you can monitor the CPU usage and disk reads and writes of your Amazon Elastic
-// Compute Cloud (Amazon EC2) instances and then use this data to determine
-// whether you should launch additional instances to handle increased load.
-// You can also use this data to stop under-used instances to save money.
-//
-// In addition to monitoring the built-in metrics that come with AWS, you can
-// monitor your own custom metrics. With CloudWatch, you gain system-wide visibility
-// into resource utilization, application performance, and operational health.
-// The service client's operations are safe to be used concurrently.
-// It is not safe to mutate any of the client's properties though.
-// Please also see https://docs.aws.amazon.com/goto/WebAPI/monitoring-2010-08-01
