Hi:

If you are interested in the amount of memory proceesses are consuming, try this:

# UNIX95= ps -e -o "user,vsz,pid,ppid,args" | awk 'NR>1' | sort -rnk2

Note the blank (space) character after the equal sign and before the 'ps' command.

The list returned is for all processes, in descending order of process size. See the 'ps' man pages for more information.

Regards!

Hi,
The best tools to do that is Glance (but it is not free). You can also use ps (yes it do that also): ps -elf, but it don't give all informations like RSS/VSS/BSS etc...but it give you still a good information about the size of a process.

Cheers.

You can look at open processes in glance and drill in to see details.

You can attach the tusc utility to a process and get every single instruction into a log file. tusc is not included on most systems and you will have to find a copy.

I am attaching my performance data collection scripts as a courtesy, you may be able to fine tune these to get you some data as well.

In addition to all above,

You can use top command to get the details.

we use several tools.

glance plus (not a fee product)
top
perfview & measureware (also not free)

perfview & measureware can get extreemly detailed information on just about ANYTHING you want to look at from cpu, memory, disk.... you name it.

glance /(glance plus) is a good real time tool for this.

In the GUI version of Glance, on the process list screen, click "configure", then "sort fields". You can then select which fields you wish to sort on - Resident Memory or Virtual Memory.

By default glance only show you processes that use more than 20000 Kbytes of RSS. What you need to do is change that value so that you get a wider range of process list.
# glance -g
==> In the glance window type "o", then choose ..
1) Process
In the "Resident Set Size" area enter "0" (ie set it to zero KBytes). Hit enter till it prompt you to confirm these settings. Confirm it with "y".

# gpm

That will give you the Glance graphical screen. Drill down the reports you needed from the "reports" menu. You will get process, memory and other resource usages from there.
