Going back to your point, while I don't need this myself anymore (although I
just see another message apparently asking for the same thing), how about
- make a new DATA type that is similar to GAUGE without smoothing
- add a rrdtool create flag for GAUGE where it's marked as no smoothing
I haven't looked at the code and can't comment on how difficult either is,
but I can think of several legitate uses for GAUGE where smoothing would not
be ok (not counting my bitfield thing, which is admittedly mabye a bit
beyond what rrdtool fields were originally meant for, even if it happens to
work great ;) ).
