// This is the Amazon CloudWatch API Reference. This guide provides detailed
// information about Amazon CloudWatch actions, data types, parameters, and

// associated API calls, go to the Amazon CloudWatch Developer Guide (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide).
//
// Amazon CloudWatch is a web service that enables you to publish, monitor,
// and manage various metrics, as well as configure alarm actions based on data
// from metrics. For more information about this product go to http://aws.amazon.com/cloudwatch
// (http://aws.amazon.com/cloudwatch).
//
//  For information about the namespace, metric names, and dimensions that
// other Amazon Web Services products use to send metrics to Cloudwatch, go
// to Amazon CloudWatch Metrics, Namespaces, and Dimensions Reference (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html)
// in the Amazon CloudWatch Developer Guide.
