This directory contains resources associated with using ETW/xperf. Most of these resources are associated with blog posts on: https://randomascii.wordpress.com/category/xperf/ For specific details on this project see this post which includes some documentation and an explanation for why this project was created: https://randomascii.wordpress.com/2015/04/14/uiforetw-windows-performance-made-easier/ The core project is UIforETW which is a graphical user interface for recording and managing ETW traces. It makes it much easier to control how traces are recorded than using batch files or Microsoft's wprui. UIforETW also works around numerous problems with ETW tracing (fixing symbol loading issues) and adds extra features such as categorizing chrome processes. UIforETW also lists all the recorded traces and displays editable notes associated with each on. UIforETW is somewhat biased towards Chrome development - it has some features that are specific to Chrome developers - but it is fully functional for non-Chrome developers as well. To use UIforETW you have to install the Windows Performance Toolkit (version 8.1 is currently the latest version) and then run UIforETW.exe. This is not an official Google project and is not supported by Google in any way.
