Hi,

I need your help to implement something to monitor CPU/MEM usage during or at the end of the execution of a perl program.

Imagine that a program that runs every N minutes which is launched by another Perl program, the execution of the latter can vary from a few seconds to 1 minute. How can I get CPU/MEM usage that result from executing this program.

some of the requirements are:

• monitoring should interfere as little as possible with the execution of the program.
• monitoring should use a minimum of system resources
• OS independent as possible. should run in Linux, Win32, HP-UX, Solaris, AIX. Ok but lets focus first in Linux.

I've thought in some approaches:

1. Implement my own Devel::MyProfiler and run the program with -d "option". (ex: $ perl -dMyProfiler program.pl)
2. Implement a wrapper that get stats every N seconds from /proc/pid or "$ ps aux", and gets the average stats at the end of the program
3. Implement a parallel program that makes a "$ ps aux" every N seconds
4. Using a process trace tool!!
5. ???

Any tip will be helpfull!!!
