How can i monitor the process memory or cpu effort ?
Which is the shell command that let me do this ??
Is there an option of "ps" shell command??
I'm working on unix server: Sun Solaris 2.7.

Thank you in advance for your help
bye

Hi
You can use sar -u 5 10 this means that it will check the load placed on your cpu every five seconds and will run ten times give you an average % for it.

Andrea,

The top command gives you the information you're asking for in an easy to read format.

Mike's right about Top, but it's not always available on Solaris media for some reason. You can download it from

http://www.sunfreeware.com.

Alternatively, cut and paste the following script )provided by one of the kind people on here, but I can never remember who:

#!/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

Hope this helps.

An old favourite: -

/usr/ucb/ps -aux | head 10 (10 highest cpu processes )

/usr/ucb/ps -auv | haed 10 (memory processes)
