It's my understanding that fetch will use the highest resolution RRA
containing the entire time interval you request (start time through
end time).  If you perform an rrdtool dump, do you see the values
you're looking for?  We need more detail about your rrd file
(specifically the RRA definitions) to be helpful.  Please send the
rrdtool create command you used to create the rrd or a full rrd dump.
