Hey all, I've been playing around with Perl's SystemTap integration (in core since 5.12.0), but I've been struggling to find any documentation on it. I've deduced enough to get info on subroutine entry/exit, but wondered what else was out there?
Also - I wondered if it was possible to create user-defined points -- I gather it's possible for the DTrace implementation (see http://search.cpan.org/~chrisa/Devel-DTrace-Provider-0.02/lib/Devel/DTrace/Provider.pm) but that code seems to be too tightly bound to DTrace to work with SystemTap. Cheers, Toby PS. Have posted up my notes on getting it going under Ubuntu at: http://blog.dryft.net/2011/03/profiling-perl-with-systemtap-on-linux.html -- Turning and turning in the widening gyre The falcon cannot hear the falconer Things fall apart; the center cannot hold Mere anarchy is loosed upon the world
