Hi Ahmed,

You can use UNIX95 variable with ps

# UNIX95= ps -ef -o sz,vsz,pid,comm

Also, Glanceplus will be helpful.

thanks Arun,
see below is the output so where is size of memory here taken by process? and can I sort it by higher usage?

SZ VSZ PID COMMAND
1098 4428 14256 cm
1410 7244 14892 cm_uat02
1098 4428 14251 cm

For calculating Mb you have to use specialised script.

Use this for reference:

get glance for feasible monistoring.

Hi Ahmed,

You can use this command as well,

UNIX95= ps -ef -o pid,ruser,vsz,args|sort -nrk3

Output will be sorted from High to low. These are in KB. You may need to convert them into MB for your need.

Use like,

UNIX95=1 ps -ef -o vsz= -o pid= -o comm= | sort -rnk1 | awk '{ print $1/1024" MB "$2" "$3; }'

will give MB size for memory usage.

Final better solution:

# UNIX95=1 ps -ef -o vsz= -o pid= -o comm= |sort -rnk1 | awk 'BEGIN{printf "Memory PID Process\n";}{ printf "%-3.2f MB %-5d %-15s\n",$1/1024,$2,$3; }'
