[rrd-users] values being averaged.

Thanks for the reply,

I had already read through the documentation, man pages and tutorials
before posting. I had also spent some time with just trial and error
where I wanted to clarify some of the examples as see what happened if.
So your assumption was wrong :-)

My biggest assumption was that the documentation was correct, this seems
to be incorrect, as the tutorial rrd_beginners
http://oss.oetiker.ch/rrdtool/tut/rrd-beginners.en.html states quiet
"GAUGE does not save the rate of change. It saves the actual value
itself. There are no divisions or calculations."

And the man page rrdcreate
http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html states:
"The data is also processed with the consolidation function (CF) of the
archive. There are several consolidation functions that consolidate
primary data points via an aggregate function: AVERAGE, MIN, MAX, LAST."

And you say the above is not correct.

It seems this tool will not do what I expected it to, and from your
abrupt reply I do not expect to get a useful answer.  Also since you did
not comment on the incorrect answer to he other post with a similar
query, I will look elsewhere.

It is impossible to have 2.3 kids, yet per household we do.

You are operating on assumptions, and these are wrong.

Please read the tutorials, the documentation and visit my site.
