# CfnAppMonitorPropsMixin

Creates a CloudWatch RUM app monitor, which you can use to collect telemetry data from your application and send it to CloudWatch RUM.

The data includes performance and reliability information such as page load time, client-side errors, and user behavior.

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.
