memory for a process

[Chris Baugh]

Does anyone know te easiest way of working out the amount of memory a particular process is using?

[Pedro Cirne]

Hi,

You can use the "top" there you have the total size, including Virtual Memory and the Resident Size, the memory currently ocupied on phisical RAM.

Enjoy :-)

You can use glance and process parameter it will give all the details

[Chris Baugh]

Isn't the memory reported by top a summary, rather than for each individual process?

[Gopi Sekar]

you can use top command to find out the current memory usage of the process.

you can also get these information through ps with some extra output tokens

Hi

Glance is a better product for this,the details are correct from the glance output.

Here's a script:

# cat /usr/local/bin/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"
