Amazon CloudWatch announces out-of-the box, best practice alarm recommendations for AWS service-vended metrics. It provides alarm recommendations and alarm configurations for key vended metrics, along with the ability to download pre-filled infrastructure-as-code templates for these alarms. Furthermore, you can now see in-line descriptions for AWS service metrics across the AWS console, which enables you to easily see metric details to help you troubleshoot or assess system health.
