Configure performance monitoring in Microsoft Azure Cloud Services

Application Insights is in preview.

Application Insights for Visual Studio Online can monitor your live web application’s performance and help you diagnose any performance issues or exceptions that occur. If there are any issues such as slow responses or uncaught exceptions, you can be notified by email. You’ll be able to open the stack trace in Visual Studio to pinpoint the problem in the code.

If your web service runs as a web role in Microsoft Azure Cloud Services, you add some scripts to your application solution in Visual Studio, and then redeploy your solution. You can monitor any web service, whether it’s an ordinary website or, for example, the server component of a phone app. The monitor collects data with very little overhead.

(There are other help topics about ASP.NET applications on an IIS server and Java web applications.
