Memory Usage by User.

[Barakati]

Hi

Could anybody show me how to find memory and cpu usage by each user and porcess.


Thanks in advance.

Hi,

You can see the cumulative usage of memory and cpu systemwise and userwise by using top, sar, glance.

If you want to know the memory usage per process you can use the too1 kmeminfo.

Hi,

use glance /kmeminfo.

'top' shows the process specific breakup of cpu%, mem (RES) etc.

[Sani]

Hi ,

glance will give all such information.

Hi ,

You can run Glance, will show memory and CPU usage by each user.
(more info man glance)

Thanks,
Johnson

ps -e -o ruser,pid,vsz=Kbytes --sort user|grep

The above would be just an approximation of usage and hence called virtual size, to get the right usage use tools like Glance Plus.

Actually i am trying to get total memory used by all processes owned by each user.

With glance i could see only a subset of process owned by each process.

On my HP_UX server memory is 98% used on an avg as seen by glance. I would like to know i) what user consumes how much memory.

Could you please clarify.

UNIX95= ps -e -o vsz=Kbytes -o pid,args=Command-Line | sort -rnk1

Hi,

I read one website stating..
For Example,

# UNIX95= ps -eo vsz,ruser,pid,args | sort -rn | more
26332 ids 1685 ./idsagent -a
5296 root 2178 /usr/sbin/stm/uut/bin/tools/monitor/fpl_em
4760 root 2713 /opt/perf/bin/rep_server -t SCOPE /var/opt/perf/datafiles/loggl
4068 root 1487 /opt/perf/bin/scopeux
4052 root 1243 /opt/dce/sbin/rpcd
3364 root 2715 /opt/perf/bin/alarmgen -svr 2714 -t alarmgen /var/opt/perf/data
3180 root 1465 /opt/perf/bin/midaemon
3148 root 1495 /usr/sbin/swagentd -r

And then look at the 1st column in the output to see the amount of memory used by this process for data/text and stack. This value is in pages, so multiply by 4096 to determine the size in bytes. Anytime you see that the size (SZ) is a four-digit number, that's relatively large, so it's one to watch over time and to see if it continues to grow, and therefore may have a memory leak.


Then i tried this.


#UNIX95= ps -eo vsz,ruser,pid,args | sort -rn | awk '{ val +=$1} END {print (val*4096)/(1024*1024*1024)}'
144.494

Do you think this value is in GB.
Is that means currently my machine using 144.494 GB? i do not think. I am trying to get the complete usage on my memory by all users. then by each users.
Is that possible using above command.

Please clarify.

[Barakati]

Thanks all i get it.

i did not concentrated on "vsz".
UNIX95= ps -eo ruser,pid,args,vsz=Kbytes |grep applmgr | awk '{ val +=$4} END {print (val)/(1024*1024)}'

will give me memory used by user "applmgr" in GB.

But if it is actual. How can i get actual using commands like this?

Thanks

[Barakati]

Hi Experts,

Do you think this command gives exact or very close to actual memory used by the user.

Because when i check the same on glance it is totally different.

with this command i sam 42.067 mb used by one user.

and it more than 500 mb on glance by the same user.

Any hints where i am going wrong.

Hi,

you can use the HP tool kmeminfo to get the memory usage by user process and Kernel.

for CPU usage, please check
# top -d5 s10
# sar -Mu 2 10
