How to detect memory leaks on RHEL releases (RHEL4, RHEL5)

How to detect memory leaks on RHEL releases (RHEL4, RHEL5)

Dear Masters

I work in a system testing team and we work on complete black box testing with no access to the code or programs.
While running traffic on the system we would like to observer if any of the process are leaking memory and if there are an leaks in the memory of the system at a high level.

Are there an tools that can be used on RHEL4, RHEL5 systems.

Any inputs in this direction is very helpful to us.

Thank you in anticipation.

Kind Regards,
Satya Prasad

In order to easy present/analyze historical data I suggest you to install some monitoring tool - Zenoss (I personally like it), Cacti, Ganglia or so on.

i can recommend valgrind - http://valgrind.org/

on RH5 you have the use of systemtap, a solaris dtrace like tool - http://sourceware.org/systemtap/

note however that none of these tools are easy, the are _great_ tools. but you need to take time to learn them.
