Performance Snapshot

VTune
Profiler
provides several analysis types that are tailored to examine various application types and aspects of performance. Performance Snapshot captures a picture of these aspects and presents an overview of the workings of your application.
Use Performance Snapshot when you want to see a summary of issues affecting your application. This analysis also includes recommendations for other analysis types that you can run next for a deeper investigation.
