Perl profiler

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

I am having a real "middle age" moment... I cannot remember the name of a programming "thing".. Here is what I need/want to do... 1. I have a huge perl program; it has tons of subs, which are well commented, but the structure is very much like a big run on sentence... 2. I need to tool that will show me the way the program logic runs whent he program is invoked...what calls what when etc... I have forgotten the name of the category of tools which does it is...someone said they thought this type of tool is called a profile...but for the life of me I cannot remember... my aged brain thanks you in advance... cid

You may want a debugger, included with Perl, or possibly a profiler: Devel::DProf. Both of these tools are very helpful, and some other code analysis tools you might want to try out on this monster are: Xref - code crossreferencing, Devel::Cover - Code coverage analysis, and Runops::Trace - trace what the perl runloop is doing from your program.

See Devel::DProf or Devel::Profiler. Update (now that I'm off my phone and back to a real browser): To get a call tree from one of those, use `dprofpp -t` or `dprofpp -T`. The lower case `-t` may be easier to read because repeated function calls are condensed and shown with a repetition count.	[reply] [d/l] [select]

Perhaps you mean a "call graph generator". Here is one (no idea as to its usefullness). This appears to be another.	[reply]
