[rrd-users] DERIVE or COUNTER

I read the manual page and see your point. Would it
be fair to say that *any* COUNTER that is zeroed on reboot would be
better off being a DERIVE? I'm not sure that detecting the difference
between an overflow and a zeroing is worth attempting, and that seems to
mean this is the only 'correct' solution.

My graphs are looking great now, by the way. ;-)

Cheers
Michael
