This analysis is deprecated in GUI and available from command line only.

TSX Hotspots analysis type uses hardware event-based sampling collection and is targeted for the Intel® processors supporting Intel® Transactional Synchronization Extensions (Intel® TSX). This analysis type uses the UOPS_RETIRED.ALL_PS hardware event that emulates precise clockticks and helps identify performance-critical program units inside transactions.


vtune -collect tsx-hotspots [-knob <knobName=knobValue>] [--] <target>

Knobs: sampling-interval, enable-stack-collection.


For the most current information on available knobs (configuration options) for the TSX Hotspots analysis, enter:

vtune -help collect tsx-hotspots
