I had a simple thought this morning: just ignore any value that's been
interpolated by cacti and throw it away.
An easy way to detect one is that it's very unlikely that it'll be an
integer, so instead of

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
this:
- make a new DATA type that is similar to GAUGE without smoothing
or
- 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 ;) ).

If you are referring to the message I posted, as I read the doc, or
at least the into, it says:<br>
<br>
<blockquote> <i>GAUGE does not save the rate of change. It saves
the actual value itself. There are no divisions or calculations.</i><br>

Which is not what I am seeing.<br>
<br>
I am (trying to) record actual numbers of items in queues. These are
integer values, not rates.<br>
As I read the doc, that is explicitly what GAUGE is supposed to
record.<br>
