It's understood about the realities of commercial decisions, however, if you really want to trace APPS that means user space dtrace and 7.2 just doesn't have the hooks to do non-kernel dtrace. As a side note, realize that Dtrace support in FreeBSD had a serious problem a couple of years ago when the lead developer suddenly dropped dead (Very literally, to out great sadness), and it took a while for alternative resources to fill the gap. > > On 2011-09-16 18:46, Matthias Andree wrote: >> Am Freitag, den 16.09.2011, 14:30 -0600 schrieb Charlie Martin: >>> I need to add some custom static dtrace probes in 7.2 apps; the >>> online >>> documentation refers only to 9 however.
