Hi John, DTrace on my unix VM thinks it does not know ioShowDisplayOnWindow (I guess because I use X11 display). With a Mac VM I it works. To trace ioShowDisplayOnWindow you don't need a dedicated probe (and hence no specialized VM). The DTrace "pid" provider allows you to trace any function entry (and return): pid$target::ioShowDisplayOnWindow:entry { printf("%s'%s\n", probemod, probefunc); } Cheers, Adrian On May 11, 2010, at 19:03 , John M McIntosh wrote:
Ah, nice, yes very nice.
One interesting one to have a probe for would be ioShowDisplayOnWindow so one can understand how much screen drawing goes on.

Now there's also a DTrace provider for the Squeak VM:

DTrace is a powerful, kernel-based dynamic tracing framework. With the new provider one can analyze the execution of Pharo/Squeak applications.
My post is an introduction that should get you quickly started. I've attached a pre-compiled VM for OS X.
Hope you like it :)
