Offlist, Neil and I found that <ds><value> is not, ah,
"trustable" for type GAUGE: enclosed is an example where we
updated a GAUGE DS with the values 1, 1, 1 but the resulting
<ds><value> value is 1.89e+02?!

Using "rrdtool fetch" acts as expected and I wrote:

 There's no problem/bug per se.  Just ignore <ds><value></value></ds> 
 and inspect the <rrd><database></database></rrd> values!

Tobi,

I'm back to thinking that RRDtool really should allow for

  % rrdtool last --values --ds ifoper:ifadmin
  947262300 1.00 1.00

or somesuch.  If you agree, I will clean up my code for that
stuff and generate v1.0.10 patches.

later
