That's neat. The modern equivalent to that these days, on Windows, is to leverage ETW and Windows Performance Analyzer. Potentially with a custom plugin that can visualize your specific perf data as a first-class WPA citizen (i.e. indistinguishable from any other perf data being analyzed, which means you can group/query/filter etc. just like anything else).

I wrote a plugin for a past employer to visualize our internal product event hierarchy performance as if it were a normal C/C++ call stack, it was pretty cool. ETW and WPA are phenomenal tools. I miss them both dearly when on Linux.
