Helps you identify the "hot" code path spending the most time handling a particular web request.
* Snapshot debugger
When an exception occurs, you can automatically collect a debug snapshot from your live web application. The snapshot shows the state of source code and variables at the moment the exception was thrown. The Snapshot Debugger in Azure Application Insights monitors exception telemetry from your web app. It collects snapshots on your top-throwing exceptions so that you have the information you need to diagnose issues in production.
