// 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 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
