You can monitor, alarm and receive notifications on the operational performance of your Amazon CloudFront distributions within just a few minutes of the viewer request using Amazon CloudWatch. CloudFront automatically publishes six operational metrics, each at 1-minute granularity, into Amazon CloudWatch. You can then use CloudWatch to set alarms on any abnormal patterns in your CloudFront traffic. To learn how to get started monitoring CloudFront activity and setting alarms via CloudWatch, please view our walkthrough in the Amazon CloudFront Developer Guide or simply navigate to the Amazon CloudFront Management Console and select Monitoring & Alarming in the navigation pane.
