Intel® VTune™ Amplifier provides the following options to run performance analysis:
Run local or remote analysis using the standalone graphical interface
Run local or remote analysis using the command line interface
Prerequisites:
For Linux* or Android* application analysis, make sure to configure your remote system and prepare your application for analysis.
For Linux targets, download and install the debug info packages available for your system version.

Analysis Results
VTune Amplifier analyzes the target, finalizes the result, and opens the collected data in the default viewpoint. The data collection results (*.amplxe file) show up in the Project Navigator under the My Amplifier Results folder, in the alphabetical order. Double-click a result to open the collected data in the default viewpoint.
Note
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 *.amplxe cannot be changed.
To change the result name template or the default directory for result location, go to Options... and select Intel VTune Amplifier 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/.
