CreateMonitor

Creates a monitor in Amazon CloudWatch Internet Monitor. A monitor is built based on information from the application resources that you add: VPCs, Network Load Balancers (NLBs), Amazon CloudFront distributions, and Amazon WorkSpaces directories. Internet Monitor then publishes internet measurements from AWS that are specific to the city-networks. That is, the locations and ASNs (typically internet service providers or ISPs), where clients access your application. For more information, see Using Amazon CloudWatch Internet Monitor in the Amazon CloudWatch User Guide.

When you create a monitor, you choose the percentage of traffic that you want to monitor. You can also set a maximum limit for the number of city-networks where client traffic is monitored, that caps the total traffic that Internet Monitor monitors. A city-network maximum is the limit of city-networks, but you only pay for the number of city-networks that are actually monitored. You can update your monitor at any time to change the percentage of traffic to monitor or the city-networks maximum. For more information, see Choosing a city-network maximum value in the Amazon CloudWatch User Guide.

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

ClientToken

A unique, case-sensitive string of up to 64 ASCII characters that you specify to make an idempotent API request. Don't reuse the same client token for other API requests.

Type: String

Required: No

HealthEventsConfig

Defines the threshold percentages and other configuration information for when Amazon CloudWatch Internet Monitor creates a health event. Internet Monitor creates a health event when an internet issue that affects your application end users has a health score percentage that is at or below a specific threshold, and, sometimes, when other criteria are met.

If you don't set a health event threshold, the default value is 95%.

For more information, see Change health event thresholds in the Internet Monitor section of the CloudWatch User Guide.

Type: HealthEventsConfig object

Required: No

InternetMeasurementsLogDelivery

Publish internet measurements for Internet Monitor to an Amazon S3 bucket in addition to CloudWatch Logs.

Type: InternetMeasurementsLogDelivery object

Required: No

MaxCityNetworksToMonitor

The maximum number of city-networks to monitor for your resources. A city-network is the location (city) where clients access your application resources from and the ASN or network provider, such as an internet service provider (ISP), that clients access the resources through. Setting this limit can help control billing costs.

To learn more, see Choosing a city-network maximum value in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 500000.

Required: No

MonitorName

The name of the monitor.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [a-zA-Z0-9_.-]+

Required: Yes

Resources

The resources to include in a monitor, which you provide as a set of Amazon Resource Names (ARNs). Resources can be VPCs, NLBs, Amazon CloudFront distributions, or Amazon WorkSpaces directories.

You can add a combination of VPCs and CloudFront distributions, or you can add WorkSpaces directories, or you can add NLBs. You can't add NLBs or WorkSpaces directories together with any other resources.

Note

If you add only Amazon VPC resources, at least one VPC must have an Internet Gateway attached to it, to make sure that it has internet connectivity.

Type: Array of strings

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: arn:.*

Required: No

Tags

The tags for a monitor. You can add a maximum of 50 tags in Internet Monitor.

Type: String to string map

Map Entries: Minimum number of 0 items. Maximum number of 200 items.

Key Length Constraints: Minimum length of 1. Maximum length of 128.

Value Length Constraints: Minimum length of 0. Maximum length of 256.

Required: No

TrafficPercentageToMonitor

The percentage of the internet-facing traffic for your application that you want to monitor with this monitor. If you set a city-networks maximum, that limit overrides the traffic percentage that you set.

To learn more, see Choosing an application traffic percentage to monitor in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No
