Add or create an Amazon CloudWatch Internet Monitor monitor with Amazon VPC
When you create a Amazon Virtual Private Cloud VPC in the Amazon Web Services Management Console, you can optionally choose to also set up monitoring for it in Amazon CloudWatch Internet Monitor. You can add the VPC to an existing monitor, or you can opt to create a new monitor for the VPC in the Amazon VPC console.
By using Internet Monitor with your VPC, you can view and evaluate measurements and metrics about availability, performance, monitored bytes transferred, and round-trip times that are specific to your application's client locations and ASNs (typically internet service providers). Internet Monitor also determines when there are anomalies in performance and availability and creates health events in your monitor, which you can choose to be notified about. To learn more about how you can use a monitor to manage and improve your clients' experience with your application, see Using an Internet Monitor monitor.
Important
To create a monitor, or add a VPC to an existing monitor, you must have the correct permissions in place. For more information, see Identity and Access Management for Amazon CloudWatch Internet Monitor.
Add a VPC to an existing monitor
You can choose to have Amazon CloudWatch Internet Monitor add a new VPC to an existing monitor for you when you create the VPC in the Amazon Web Services Management Console. After you add the VPC, wait a few minutes, and then metrics for the VPC will start being shown on the Internet Monitor console.
You can edit the monitor at any time, to remove the VPC or add another VPC or other resources. You can also change the percentage of traffic that you're monitoring, or make other changes. If you choose to remove the VPC from the monitor, traffic from clients to that VPC is no longer monitored by Internet Monitor.
To learn more about updating a monitor, see Editing or deleting an Internet Monitor monitor.
Create a monitor for a VPC
If you opt to create a monitor for a VPC, the Create monitor wizard walks you through the steps. You add the VPC as a monitored resource when you create the monitor. If you like, you can also choose a percentage of client traffic that you want to monitor for your application (the default is 100%).
You can learn more by reviewing the information in Creating a monitor in Amazon CloudWatch Internet Monitor using the console.
Pricing
With Amazon CloudWatch Internet Monitor, you pay only for what you use. Pricing for Internet Monitor has two components: a per monitored resource fee and a per city-network fee. A city-network is the location that clients access your application resources from and the network (an ASN, such as an internet service provider or ISP) that clients access the resources through.
