re 10: I'm the author of collectl. If there's something inconsistent with the documentation could you let me know what is?

While I don't have any quick answers to the problem of finding the guilty process, one thought that comes to mind is to try a smaller monitoring interval, something you can to do with most of the 'standard' utilities. For example you could do

collectl -i.1 --vmstat -oT

to see the same output vmstat would show, only prefaced with a timestamp and you'd see one sample every second. If that's not enough you could try 0.01 seconds or anything in between but that's probably overkill. 9-)

you could also try

collectl -i.1 --top

to see what top might show or even

collectl -i.1 -sD

to see what iostat would show. far too many other commands to show here, but you could always look at collectl.sourceforge.net
