Description

Use the loop-mode option when performing data collection, finalization or importation, to set loop view for the result or report. You can also use this option with the report action to override the project-level setting for viewing a hierarchy of the loops in your application call tree.

Example

This command displays the data collected during the Hotspots analysis in the callstack report that is filtered to show loops only:

vtune -R callstacks -loop-mode=loop-only
