Instrumentation plugin for Qt Creator

Next to the Static Code Quality plugin, I'm also researching an instrumentation plugin for Qt Creator.

This instrumentation plugin will use tools like Systemtap and DTrace. This unfortunately limits the plugin to unix/linux systems. Windows does not contain, as far as I know, tools like Systemtap or DTrace, or they will be extremely expensive. I would love to know a Windows alternative I can use for this plugin.

The goal is the get something similar like Apple Instruments inside Qt Creator.
However, I'm still experimenting with ideas and implementations, so no concrete goals yet.
