Callstacks Report

Intel® VTune™ Profiler collects call stack information during User-Mode Sampling and Tracing Collection or Hardware Event-based Sampling Collection with stack collection enabled. Use the callstacks report to see how the hot functions are called. This report type focuses on call sequences, beginning from the functions that take most CPU time.

You can use the -column option to filter the callstacks report and focus on the specific metric, for example: 

vtune -report -callstacks -r r001ah -column="CPI Rate"

NOTE:

To display a list of columns available for callstacks report, enter: vtune -report callstacks -r <result_dir> column=?

Examples

Example 1: Callstacks Report with Limited Items

The following example generates a callstacks report for the most recent analysis result and limits the number of functions and function stacks to 5 items. 

vtune -report callstacks -limit 5
