There are several ways to use an Amazon CloudWatch Internet Monitor monitor after you create it: for example, you can view information in the CloudWatch dashboard, get information by using the Amazon Command Line Interface, and set health alerts.

Your monitor provides information about your application and configuration preferences so that Internet Monitor can customize measurements and metrics to publish in events for you. Internet Monitor collects measurements from the global infrastructure footprint for Amazon. These measurements are a tremendous amount of network performance and availability information, from all over the world. By using information from the resources that you add for your application, Internet Monitor publishes performance and availability measurements for you that is scoped to the city-networks (that is, client locations and ASNs, typically internet service providers or ISPs) where your application is active. So, the measurements and metrics in the Internet Monitor dashboard and in CloudWatch Logs —about availability, performance, monitored bytes transferred, and round-trip time—are specific to your client locations and ASNs.

Internet Monitor also determines when there are anomalies in performance and availability. By default, Internet Monitor overlays your traffic with the availability and performance measurements that Amazon has collected for each source-destination pair in your client locations, to determine when there are notable drops in performance or availability.
