Does Call Graph collector work on pure unmanaged code?

Does Call Graph collector work on pure unmanaged code?

Hi,

Our entire database server software package is unmanaged code and most of them is in ring 3 and few of them is ring 0. Thesoftware consists of many different processes (running in many threads) and dll. I tried to intrument one .EXE filecall graphand have no luck. Similarly, Ihave no luck ononedll file (user code)instrumentation. I tried instrumenation level -- minimal, exports, or all functions which lead me the same result --- No module from the activity was loaded. No results were generated for this run.

I have no problem on Sampling and Counter.

Intel Vtune book states that Call graph can work on managed code or mix of managed & unmanaged code. This seems implying that unmanaged code is not instrumentable by vtune. Am I missing something?? Or manybe the way I set up my activity and call graph is incorrect??

Your help & advice will be greatly appreciated.

Judy
