Memory Cosumption

HutchAdmin — Thu, 06 Nov 2003 03:08:26 GMT

Hi,

Can any one tell me how can I extract the details of memory consumptions. I need the following details.

Total Memory
Memory Used
Unused Memory

Thanks

Glance is a good tool for this if you have it.

Otherwise

"dmesg" shows how much physical RAM you've got (at least for a while). The only other way I have found of getting actual memory is with "c" and using "pstat_getstatic()" system call and multiplying the physical memory value by 4. I can attach an example program if you like.

"vmstat" is good for showing average memory and free memory (in pages).

grep -i physical /var/adm/syslog/syslog.log --> gives RAM in machine.

glance -m Gives details abt used, free mem.

vmstat 5 5 -- check free mem column. (free memory in pages. each page is 4096 kb)

Hi,

Glance is the tool you need. It is free for 60 days. If you install it, you are able to view memory usage per proces.

For total memory, here's a little script I use:

HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

MYMEM=$(echo "${MYSYMBOL}/D" \
| adb $HPUX /dev/kmem \
| grep "${MYSYMBOL}: *." \
| awk '{printf "%.0f MB\n",$2/256}')
echo $MYMEM
