Call Count

Enable the stack collection for the hardware event-based sampling analysis and configure the Intel® VTune™ Amplifier to statistically approximate the number of calls to sampled functions.

1. Click the New Analysis button on the VTune Amplifier toolbar.

   The New Amplifier Result tab opens with the Analysis Type window active.

2. In the Analysis Type window, select the Algorithm Analysis > Advanced Hotspots analysis type from the left pane.

   The Advanced Hotspots configuration pane opens on the right.

3. From the Collection level options, select Hotspots, call counts, stacks and context switches.
4. Click the Start button on the right to run the analysis.

   VTune Amplifier collects the data statistically estimating the number of calls to each function and provides the analysis data in the Estimated Call Count column in the Hotspots viewpoint.
