quite honestly there are so many stats I'm not that familiar with all of
them in detail. for example memory stats come from /proc/meminfo and
/proc/vmstat and virtually all utilities that report the same data. might
be helpful to look at some other utilities to confirm they're reporting the
same numbers and how they've documented it. if there are better words I can
add to collectl descripting I'll be happy to do so

Hello.
I was emptying out a swap volume (swapoff) and looking at the output of
collectl -sm --verbose -oT , while trying to make sense of a system with
a continuously rising swap occupation despite vm.swappiness set to 0.
Since the total swap memory was progressively shrinking down from a few
hundreds MB, I can't quite understand the values of swapped-in memory in
the GB range ( e.g. 6220M, 8536M ).
Is it a collectl bug or just a misunderstanding of mine?
