I want to get the total memory usage.
I have tried topas,
MEMORY
Real,MB 15808
% Comp 28.5
% Noncomp 72.4
% Client 72.4

PAGING SPACE
Size,MB 8192
% Used 1.2
% Free 98.7

but don't know which one is it.

try this scripts, then you see the real memory usage:

#!/bin/ksh
clear
echo "`/usr/bin/svmon -G `">xx
cat xx|grep memory|awk '{print $2"\t"$3"\t"$4}'>mem_frames
cat xx|grep pg |awk '{print $3"\t"$4}'>mem_pages
echo "Real memory Usage"
echo "-----------------------------"
cat mem_frames|while read size inuse free
do
rsize=$(printf "%s\n" 'scale =5; '$size'/1024/1024*4' | bc)
rinuse=$(printf "%s\n" 'scale =5; '$inuse'/1024/1024*4' | bc)
rfree=$(printf "%s\n" 'scale =5; '$free'/1024*4' | bc)
percent=$(printf "%s\n" 'scale =3; '$inuse'/'$size'*100' | bc)
echo "Total Installed : $rsize GB"
echo "Total Used : $rinuse GB"
echo "Total Free : $rfree MB"
echo "REAL MEMORY USAGE : % : $percent"
echo "-----------------------------"
done
echo ""


cat mem_pages|while read pgsize pginuse
do
paging_size=$(printf "%s\n" 'scale =5; '$pgsize'/1024*4' | bc)
paging_used=$(printf "%s\n" 'scale =5; '$pginuse'/1024*4' | bc)
percent2=$(printf "%s\n" 'scale =3; '$pginuse'/'$pgsize'*100' | bc)
echo "Paging Space Usage"
echo "-----------------------------"
echo "Total Pg Space : $paging_size MB"
echo "Pg Space Used : $paging_used MB"
echo "Percent Used PAGING : $percent2"
echo "-----------------------------"
done

What is your definition of "total memory usage"?

If you simply look for "non-free" physical memory, or, "active virtual
memory" (that is, the amount of virtual memory being used for all
programs, regardless in ram or paging space, excluding file cache),
then "vmstat" is the easiest tool, and you can run it as any user.

See,

(check the description for "avm" and "fre")
