Amazon CloudWatch Internet Monitor New2023年〜
A service that monitors application performance and availability over the internet
What It Does
Amazon CloudWatch Internet Monitor is a service that monitors the internet-facing performance and availability of your applications. Leveraging AWS global network intelligence, it detects latency, packet loss, and availability issues by ISP and region.
Use Cases
Used for monitoring the performance of globally deployed web applications, detecting access issues with specific ISPs or regions, and providing data to inform CloudFront and Route 53 routing optimization decisions.
Everyday Analogy
Think of it like a road traffic information system. It provides real-time visibility into congestion (latency) and road closures (outages) on each road (ISP), helping you choose the optimal route (routing).
What Is Internet Monitor?
CloudWatch Internet Monitor is a service that monitors your application's internet performance from the end user's perspective. Register CloudFront distributions or VPCs as monitoring targets, and it displays city- and ISP-level performance metrics based on AWS global network data.
Health Events and Notifications
Internet Monitor generates health events when it detects performance or availability degradation. It shows the affected cities, ISPs, and traffic volume, helping you understand the scope and impact of the issue. You can integrate with EventBridge to trigger automatic notifications or response actions when health events occur. For practical tips on leveraging health events and notifications, books (Amazon) are also a helpful resource.
Getting Started
Create a monitor in the Internet Monitor section of the CloudWatch console and select the resources to monitor (CloudFront distributions, VPCs). Specify the percentage of traffic to monitor and set health event thresholds.
Things to Watch Out For
- Billed based on the number of monitored resources and traffic volume
- Monitoring is based on AWS global network data, so traffic that does not pass through AWS is not covered
