    VTune
    Profiler
    stops collecting data and displays the warning message:
    Collection was cancelled by the user. The data cannot be displayed.

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/.
