I'm having some troubles getting scripts that use the profile::
stuff to work in 11.0. They seem to do exactly nothing:
<1:02pm>macpro03/gallatin:darwin>sudo /usr/bin/cpuwalk.d
Sampling... Hit Ctrl-C to end.
<wait 60 seconds>
^C
<1:03pm>macpro03/gallatin:darwin>
Whereas on a different mac running 10.x, it works:
<DING!>macpro02/gallatin:~> sudo /usr/bin/cpuwalk.d
Sampling... Hit Ctrl-C to end.
^C
PID: 18 CMD: notifyd

Is there some trick to getting dtrace profiling to work in Lion?
Thanks,
Drew
