Open Analysis Results

VTune
Profiler
 analyzes the target, finalizes the result, and opens the collected data in the default viewpoint. The data collection results (
*.
vtune
 file) show up in the Solution Explorer (for the
VTune
Profiler
 integrated into Visual Studio)/Project Navigator (standalone) under the project folder, in the alphabetical order. For executable files imported to the Visual Studio project, the data result node appears at the solution level. Double-click a result to open the collected data in the default viewpoint.
  • You can provide a meaningful name for the result (for example, application name) for better identification. To do this, select the result, right-click and choose
    Rename
    . The file extension
    *.
    vtune
     cannot be changed.
  • To change the result name template or the default directory for result location, go to
    Tools > Options
     (or
    Options...
     in the standalone interface menu) and select
    Intel VTune
    Profiler
    version
     > Result Location
     from the left pane of the
    Options
     dialog box.
  • You may program hot keys to start/stop a particular analysis. For more details, see http://software.intel.com/en-us/articles/using-hot-keys-in-vtune-amplifier-xe/.
