how to get memory info from python?

[Gardner Pomper]

Hi,

I'm pretty new to python, but I have not found any way to find out how much
memory is being used by my python application. I have some fairly large data
to load in and I am concerned about hitting the 2GB limit on my 32 bit
processes.

I would like to have the program check itself for memory usage. I know I can
get the memory information from a 'ps -l'. Btw, I will be running on AIX and
linux, although I may do some development on Windows.

I posted a similar question awhile back but have not been able to get any
info. I wanted to see if Python could be embedded in game consoles -- but
the lack of memory info is a dealbreaker. If you look in google there are a
lot of people asking this same question with no info!

Well.....
I little poking around in obmalloc.c came up with:

/* Print summary info to stderr about the state of pymalloc's
structures.
* In Py_DEBUG mode, also perform some expensive internal consistency
* checks.
*/
void
_PyObject_DebugMallocStats(void)
{

}

obmalloc.c also has a LOT of infomation about Pythons memory in
comments.

So there's certainly the possibility of a roll-your-own. although
maybe only for the DEBUG build.

obmalloc.c also has a LOT of infomation about Pythons memory in
comments.

But obmalloc.c has a high performance penalty and can't be recommend
for productivity systems that must work on a game console.
