Are you sure rrd_fetch is what you want?  The format given on
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/doc/rrdfetch.en.html
states that rrdfetch requires a CF (consolidation function).  This means
it's going to "do something" to the raw data - e.g. average it.  From
your description it sounds like you want raw values.  Maybe you want
something more along the lines of rrdxport
