NOTE – A new version of the Amazon CloudWatch User Guide is available at https//www.amazon.com/dp/B07643SJ8F This is official Amazon Web Services (AWS) documentation for Amazon CloudWatch. This documentation is offered for free here as a Kindle book, or you can read it online or in PDF format at You can use Amazon CloudWatch to monitor, manage, and publish various metrics on your AWS cloud resources, as well as configure alarm actions based on data from metrics. This guide provides conceptual information about CloudWatch and shows you how to use the service to create new web applications or integrate with existing ones. You can use this guide to program using the command line interface (CLI) or the Query API. This guide also explains how to integrate CloudWatch with other Amazon Web Services, such as Amazon Elastic Compute Cloud (Amazon EC2), Elastic Load Balancing, Amazon Simple Notification Service (Amazon SNS), and Auto Scaling.
It's full of examples on how to configure CloudWatch. Lacks a big picture view and the structure is unfit for reference. I would like Amazon to move this guides to searchable repository and make the guide a more big picture that's helps users understand the thinking behind the API.
