Swapped out memory size


I am working on finding out the memory usage of my application for past few todays.

I too posted some question's here earlier.

Ok now i come to know that the
Memory Usage = Resident size + Swaped out memory size of the particular process.

I can get the Resident set size through ps command.

I want to know , how i can find the Swapped out memory size of the particular process.

second question

As my application spawn's 'n' threads , to calculate memory usage , whether, i need to consider all the threads or the memory usage of the parent process is enough.

Pl. help me

Thanks in advance

Here is the brutal way (if you have enough RAM): disable swap. Type:
swapoff /dev/hdx
with x the letter of your swap partition.
Then compare with the usage when swap is on.

try this:
ps -aux |grep -v CPU | awk '{print "UID: " $1 " " "%MEM: " $4 " " "VMSZ: " $5 " " "RESMSZ: " $6" " "CMD:" $11}' | sort -nk 4,4

VMSZ Virtual memory size in bytes.
REMSMZ Resident Set Size

check the man on proc for greater detail
