Adding resources to your monitor - Amazon CloudWatch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Adding resources to your monitor

When you create a monitor, you associate your application's resources with it: Amazon Virtual Private Clouds (VPCs), Network Load Balancers, Amazon CloudFront distributions, or Amazon WorkSpaces directories. Then Internet Monitor knows where your application's internet-facing traffic and clients are located, so it can determine the relevant measurements to publish for your monitor.

You can add the following resources to a monitor in Internet Monitor.

  • VPCs: Each VPC that you add in a Region is a monitored resource. When you add a VPC, Internet Monitor monitors the traffic for any internet-facing application in the VPC, for example, an application hosted on an Amazon EC2 instance, behind an Network Load Balancer, or in an Amazon Fargate container.

  • Network Load Balancers: Each NLB that you add is a monitored resource.

  • CloudFront distributions: Each CloudFront distribution that you add is a monitored resource.

  • WorkSpaces directories: Each WorkSpaces directory that you add in a Region is a monitored resource.

When you monitor traffic for VPCs, traffic for applications that are hosted on load balancers behind the VPC is monitored. You can choose to monitor traffic for individual Network Load Balancer load balancers instead of monitoring a VPC with multiple load balancers. This can be helpful, for example, if you need to understand and configure features for better performance or efficiencies at the load balancer level. Or, you might need compliance information at the Network Load Balancer level.

When you add resources to a monitor in Internet Monitor, be aware of the following:

  • VPCs that you add must be connected to the internet with an Internet Gateway configured.

  • You can add a combination of Amazon VPC and CloudFront distributions, or you can add WorkSpaces directories, or you can add Network Load Balancers. You can't add Network Load Balancers or WorkSpaces directories together with other types of resources.

There are Regional differences for opt-in Regions to keep in mind when you add VPCs and NLBs as resources. For more information, see Supported Amazon Web Services Regions for Amazon CloudWatch Internet Monitor.

In addition, there are differences for resources about measuring last-mile latency. For Internet Monitor latency measurements, VPCs, NLBs, and WorkSpaces directories do not include last-mile latency.
