Hi all
Recently I dig out my old script that count the total number of
swapped out pages. Basically, the script looks like this (sorry for
any obvious typo):
for a in /proc/[0-9]*
do strings $a/cmdline;
echo ;
grep Swap $a/smaps | awk '{ SUM += $2 } END { print SUM }';
echo ----------------;
done
the problem is: the total number of swapped out pages (in kilobytes)
doesn't match the output of "free" (swap used column). The difference
is not really big, it ranges around 1-2 megabytes in my measurements.
Anybody knows why?
