Hi..

This may help you

Or download top utility for solaris from sunfreeware.com


Thanks

I have some restrictions on dowloading the TOP utility in my environment. Is there any other way we can find the memory for each application.

Cut and paste the following into a script:
========Start cut below====================
#!/bin/sh
############################################################
PS=/bin/ps
CUT=/usr/bin/cut
SORT=/usr/bin/sort
HEAD=/usr/bin/head

if [ -x $PS -a -x $CUT -a -x $SORT -a -x $HEAD ]
then
echo
echo " %CPU PID TIME VSZ USER COMMAND"
echo
$PS -aef -o pcpu= -o pid= -o time= -o vsz= -o user= -o args= |
$CUT -c -130 | $SORT -r | $HEAD -10
else
exit 1
fi
======================End cut above===================

Can't claim the credit for this as it's someone else's (sorry I forget who exactly), but it seems to work OK. HTH.

Hi

I found VSZ for one application is 14488 and my pagesize is 8192. Does it mean that the memory taken by that applicaton is 14488*8192 = 118685696

pls explain

The first column (%CPU) gives you the percentage CPU the particular process is using, and will hopefully give you some idea of how memory-hungry your applications are. Cheers.

i got it..

VSZ - The total size of the process in virtual memory, in kilobytes.

thx KEN

 

[KenCunningham]

Well done. Glad to have been of help.

Ken

Right now if the application is in the sleep mode we are unable to find the VSZ using that script. I need to stop and start that application then i am able to know the memory usage. Is it possible to find the memory using the PID.

First i can do ps -edf | grep <app>

then with that pid i want to know how much memory it is taking in sleep mode....

Pls do the needful
