in reply to Tracking memory of a running application

If you don't need exact size (that is, you only want to track the memory perl uses, and not the memory used by XS modules loaded, or libraries those modules use, and don't mind a little slop on top of that) you can use Devel::Size, hand it your top-level namespace pointer, and let it rip. It will use a pretty massive amount of memory itself as it runs, so don't be too surprised.

Usage is:

use Devel::Size qw(total_size); print total_size(*::), "\n";

    See Re: Total Memory Size Used up by a Perl Script for a little further info.

      Huh. I thought I'd fixed the warnings that you've seen in one of the recent versions of Devel::Size, but maybe not.

      I've an outstanding patch for it, so maybe I'll poke at the thing a bit and push out a new release with fewer warnings.

[Corion]: And the second rule that I've learned is, that there is no one-off job, so writing a program for it pays off almost immediately. The third rule is to give all my programs numbers and have them reproduce that number in the name of their output files. :)
[Discipulus]: the true part is that also specification change between years.. but well our job is cheap but dont abuse of us.. ;=)
[LanX]: Choroba: do you miss chaos with ties? apply at the US government.. ;)
[ambrus]: Corion: those are good rules.
[ambrus]: Discipulus: oh sure. the input data has different filenames every time I get them.
[ambrus]: the directory structure may be 1, 2, or 3 deep, it may have spaces in the filename or not, it has dates in various format, different keywords for the same meanings, and the dates and other keywords are assembled in various ways.
[Discipulus]: no ambrus by specification i mean for example license per core instead of per socket, so fields are different
