Analyzing the health of back-end services by using Visual Studio Application Insights

Application Insights  is an extensible analytics service that monitors your live application. It
helps you to detect and diagnose performance issues and to understand what users actually do with
your app. Application Insights designed for developers to help you to continuously improve the
performance and usability of your services or applications.

Application Insights works with both web/services and stand-alone apps on a wide variety of
platforms: .NET or J2EE, hosted on-premises or in the cloud.

Application Insights is aimed at the development team. You can use it to do the following:
 Analyze usage patterns to understand your users better and to continuously improve your app.

 Count page views, new and returning users, geolocation, platforms, and other core usage
statistics.

 Trace usage paths to assess the success of each feature.

 Detect, triage, and diagnose performance issues, and fix them before most of your users are
aware.

 Get alerts on performance changes or crashes.

 Explore metrics to help diagnose performance issues, such as response times, CPU usage, and
dependency tracking.

 Get availability tests for web apps.

 Gain insight from exception reports and alerts.

 Access the powerful diagnostic log search (including log traces from your favorite logging
frameworks).
