Tracking Memory Usage

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

Assuming that I don't want to recompile Perl with -DDEBUGGING_MSTATS, what's the easiest way to determine memory usage on RH9 Linux (RAM and swap)? Is it to manually read the /proc/$$/statm file?

I'm playing around with tail recursion techniques and it looks like goto &code is leaking memory. This appears to be a known issue, even though perl561delta lists this problem as fixed and I'm using 5.8.0 (yeah, I know. I need to upgrade).

Cheers,
Ovid

what's the easiest way to determine memory usage The memory profiling thread covered several alternatives.	[reply]

Proc::ProcessTable is useful but it cycles thru all the pids everytime you want to update, which isn't a leak, but it's alot of overhead.

Perhaps GTop might be what you are looking for. e.g. under mod_perl I use it to find out about the shared memory size... Best regards, perl -e "s>>F>e=>y)\martinF)stronat)=>print,print v8.8.8.32.11.32"	[reply]
