Process memory usage

jpcast_real — Tue, 06 Apr 2004 08:39:39 GMT

I have look at the ps and fuser options to know if it is possible to know the amount of memory a process is using , but I havn't found anything. I need the same information of a process I get with the TOP command but with a tool which lend me integrate it into a script..

Thanks

Hello,

Look at the ps -o option.
Consider also glance.

Try this script:

# cat usermem

#!/bin/ksh
# usermem - display memory claimed by a user
# gwild 06232003
#
if [ $# -lt 1 -o $ $# -gt 1 -a $# -lt 4 $ ]
then
echo "Usage:"
echo "usermem \"userid\""
echo "Example:"
echo "usermem gwild"
exit 1
fi
echo " "

USER=$1
t=0
for j in `UNIX95= ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line | sort -rnk1 | grep -v Kbytes | grep $USER | awk '{print $1}'`
do
t=`expr $t + $j`
done
echo "\nMemory claimed by $USER: $t Kbytes.\n"

Or this one:

# cat processmem
#!/bin/sh
# processmem - display memory claimed by a process
# gwild 03192004
#
if [ $# -lt 1 -o $ $# -gt 1 -a $# -lt 4 $ ]
then
echo "Usage:"
echo "processmem \"process\""
echo "Example:"
echo "processmem rpc"
exit 1
fi
echo " "

PROCESS=$1

mps=0
#for sz in `ps -elf | grep $PROCESS | grep -v grep | awk '{print $10}'`
for sz in `UNIX95= ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line | sort -rnk1 | grep -v Kbytes | grep $PROCESS | awk '{print $1}'`
do
mps=`expr $mps + $sz`
done
#echo `expr $mps \* 4096`
echo "\nMemory claimed by $PROCESS: $mps Kbytes.\n"

UNIX95= ps -C "Your_process" -o "vsz,args,ruser,pid"

Will give you memory size in KB. Also you can check text mem size of your process with
ps -efl|grep your_process. The SZ colums is size in pages. Check man page of ps.

Also you can get that with glance.

This is what I get when I execute the option -o :

Dartanan:/etc> ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line
ps: illegal option -- o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup]
[-Z psetidlist]
Dartanan:/etc> ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line
ps: illegal option -- o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup]
[-Z psetidlist]

Now do a
