I've ported my additional DTrace probes to blead perl, adding the following probes

• new-sv and del-sv to track Perl allocations,

• main-enter and main-exit to show what part of Perl's execution phase we're in

• load-module-entry and load-module-return to instrument use, require, do.

I've also started to document the probes at http://wikis.sun.com/display/DTrace/perl+Provider

To use the patch, get bleadperl:

1. $1

apply the patch: cd bleadperl ; patch ../bleadperl.diff run configure with dtrace enabled:

1. $1

make make test make install run./perl.d (also found at http://distributedinformation.com/DTrace/ ) and then run whatever Perl code you want to instrument.
