Memory management

[Joe Profaizer]

What's a quick and easy way to identify memory allocated to individual processes? Or which processes are memory hogs?

Thanks!

vmstat,top.

I would use:

top

...jcd...

Glance is the tool of choice but a quick and dirty way to do this (and the price is right!)
is:
ps -el | grep -v "PID" | sort -r -k10,10

This will sort the process list in reverse order of SZ.

You probably also should look at shared memory via ipcs -ma.

Hi Joe:

Several things come to mind:

Probably the easiest is this script from Bill Hassell:

# UNIX95= ps -e -o "user,vsz,pid,ppid,arg" | sort -rnk2 | more

'glance' and 'top' are very useful tools, too.

'ipcs' displays information in short format for the message queues, shared memory segments, and semaphores that are currently active in the system.

Hi Joe,
with glance you can select a individual process and obtain a detailed report of the diferents kinds of memory it uses (text, data, stack, shmem).
Other tool that report individual use of memory is top and "ps -l"(in physical pages) but are less detailed and even can give a wrong measure.

Joe,

If you have a recent version of Glance, try this:

glance -adviser_only -syntax /opt/perf/examples/adviser/proc_mem_leak
