This one's for Dougie following this week's meeting -- the attached file
is a better script for analysing swap usage as reported
Save it somewhere, chmod it so that it's executable, and run it
(possibly via sudo if you can't read all of the files in /proc/*/smaps)
and it will output swap usage (in kB), process PID and process name.
You can bung it though sort -n to order by swap usage.
Random note 1: http://weather.ou.edu/~apw/projects/stress/ (which is in
the Debian archives as package 'stress') was very useful for making my
system return non-zero results with this script.
Random note 2: I haven't programmed in perl in a couple of years, and
I've forgotten *everything*. Writing that script was far harder than
it should have been, and I completely failed to come up with a utterly
obfuscated one-liner, which was my real goal.
Random note 3: I've absolutely no idea how accurate the smaps
information is. Google might know that.
