With the Application Insights JavaScript SDK you can collect and investigate the performance and usage of your web page or app. Historically we have offered onboarding through manually adding a script to your application and redeploying. Manually adding the script is still supported, but recently we have added the ability to add client-side monitoring from the Azure portal in a few clicks as well.
If you have enabled Application Insights in Azure, you can add page view and user telemetry. You can learn how to switch on server-side monitoring in our documentation.

Read about it on the Azure blog.
