CreateAppMonitor - CloudWatch RUM


Creates a Amazon CloudWatch RUM app monitor, which collects telemetry data from your application and sends that data to RUM. The data includes performance and reliability information such as page load time, client-side errors, and user behavior.

You use this operation only to create a new app monitor. To update an existing app monitor, use UpdateAppMonitor instead.

After you create an app monitor, sign in to the CloudWatch RUM console to get the JavaScript code snippet to add to your web application. For more information, see How do I find a code snippet that I've already generated?

Request Syntax

POST /appmonitor HTTP/1.1 Content-type: application/json { "AppMonitorConfiguration": { "AllowCookies": boolean, "EnableXRay": boolean, "ExcludedPages": [ "string" ], "FavoritePages": [ "string" ], "GuestRoleArn": "string", "IdentityPoolId": "string", "IncludedPages": [ "string" ], "SessionSampleRate": number, "Telemetries": [ "string" ] }, "CustomEvents": { "Status": "string" }, "CwLogEnabled": boolean, "Domain": "string", "Name": "string", "Tags": { "string" : "string" } }

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.


A structure that contains much of the configuration data for the app monitor. If you are using Amazon Cognito for authorization, you must include this structure in your request, and it must include the ID of the Amazon Cognito identity pool to use for authorization. If you don't include AppMonitorConfiguration, you must set up your own authorization method. For more information, see Authorize your application to send data to AWS.

If you omit this argument, the sample rate used for RUM is set to 10% of the user sessions.

Type: AppMonitorConfiguration object

Required: No


Specifies whether this app monitor allows the web client to define and send custom events. If you omit this parameter, custom events are DISABLED.

For more information about custom events, see Send custom events.

Type: CustomEvents object

Required: No


Data collected by RUM is kept by RUM for 30 days and then deleted. This parameter specifies whether RUM sends a copy of this telemetry data to Amazon CloudWatch Logs in your account. This enables you to keep the telemetry data for more than 30 days, but it does incur Amazon CloudWatch Logs charges.

If you omit this parameter, the default is false.

Type: Boolean

Required: No


The top-level internet domain name for which your application has administrative authority.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 253.

Pattern: ^(localhost)|^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$|^(?![-.])([A-Za-z0-9-\.\-]{0,63})((?![-])([a-zA-Z0-9]{1}|^[a-zA-Z0-9]{0,1}))\.(?![-])[A-Za-z-0-9]{1,63}((?![-])([a-zA-Z0-9]{1}|^[a-zA-Z0-9]{0,1}))|^(\*\.)(?![-.])([A-Za-z0-9-\.\-]{0,63})((?![-])([a-zA-Z0-9]{1}|^[a-zA-Z0-9]{0,1}))\.(?![-])[A-Za-z-0-9]{1,63}((?![-])([a-zA-Z0-9]{1}|^[a-zA-Z0-9]{0,1}))

Required: Yes


A name for the app monitor.

Type: String

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

Pattern: ^(?!\.)[\.\-_#A-Za-z0-9]+$

Required: Yes


Assigns one or more tags (key-value pairs) to the app monitor.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.

Tags don't have any semantic meaning to AWS and are interpreted strictly as strings of characters.

You can associate as many as 50 tags with an app monitor.

For more information, see Tagging AWS resources.

Type: String to string map

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

Key Pattern: ^(?!aws:)[a-zA-Z+-=._:/]+$

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

Required: No
