create an execution graph / Devel::DProf doesn't work with POE

saxman25 has asked for the wisdom of the Perl Monks concerning the following question:

hi, I have an application written in perl which makes use of POE (http://search.cpan.org/~rcaputo/POE-1.003/lib/POE.pm).

Now I like to use Devel::DProf on this application for creating an execution graph of the script. But end up with the bug mentioned here:
http://search.cpan.org/~rgarcia/perl-5.10.0/ext/Devel/DProf/DProf.pm#BUGS

The culprit is within the POE:
panic: Devel::DProf inconsistent subroutine return at /usr/lib/perl5/vendor_perl/5.10.0/POE/Kernel.pm line 798.

My question:
Are there any similiar possibilities for extracting this kind of information which don't stumble over POE?
Or any other way to automatically generate something like an execution graph while running a skript? (not just "dry parsing" of code but following the exact execution during runtime)

thanks

for creating an execution graph of the script. Try Devel::Trace, then turn that into a graph :)	[reply]

thanks. but how can I translate the output of Devel::Trace into a execution graph? dprofpp can't handle the format of the Trace. is there a more general visualisation tool that allows to configure the syntax of the input file? or a module which generates dprofpp compatible output?	[reply]

Devel::DProfLB is compatible with, and produces the same output as Devel::DProf, but with fewer bugs.	[reply]

thanks a lot! yes, DProfLB can handle the POE.	[reply]
