I'm looking at the output of i() and observer's processes tab and am
really struggling to make sense especially of the latter.

Most processes have zero Reds if I believe observer. Then a couple of
seconds later they don't. Or is it telling me Reds since I started looking
? i() output certainly makes more sense.

Do they use different units for heap and stack ?

Should I see anything that nearly agrees (taking into account the fact
that many processes are always changing) ?

Or is it that there is room for better documentation (otherwise this tool
seems somewhat untrustworthy) ?

This is emulator 5.9.3.1 on XP.

Jon

Observer reports (by default) the reductions since last update,
you can change that in the View menu, with accumulate.
And you can change the refresh rate.

The memory comes from process_info(Pid, memory) see doc on that.
