Which process use what amount of memory

[Jonathan Caplette_1]

I guys,

I would like to know how I can know what process use how much of the memory... I got a machine that is very slow... and when I do a "top", the CPU are idle at about 98%, the memory (free) is now at 9MB on a total of 4GB... Here is the output of top:

Load averages: 1.88, 1.90, 1.89
285 processes: 280 sleeping, 4 running, 1 zombie
Cpu states:
CPU LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
0 1.90 0.0% 0.0% 1.6% 98.4% 0.0% 0.0% 0.0% 0.0%
1 1.89 0.2% 0.0% 0.4% 99.4% 0.0% 0.0% 0.0% 0.0%
2 1.64 0.0% 0.0% 0.8% 99.2% 0.0% 0.0% 0.0% 0.0%
3 2.09 0.0% 0.0% 0.4% 99.6% 0.0% 0.0% 0.0% 0.0%

Glance is not free but it has a 60 day trail available. This tool can do the job.

This tool can also get you that information.

Attaching a background perf data collector as well.

Hello,

Try :

UNIX95= ps -e -o ruser,vsz,pid,args | sort -rnk2 | more

Add on note to my previous post. There is a space behind the equals sign in the command I posted.

Check zombie from list.

Here's one I use:

#!/bin/sh
# memtop - show top memory users and pid
# VSZ is in KB
echo "VSZ(KB) PID RUSER COMMAND"
UNIX95= ps -e -o 'vsz pid ruser args' |sort -nr|head -30
