Altering the *.cfg file, I've managed to create an *.rrd db file
that updates normally and looks like this:

                  ds0           ds1

 982578000: 6.5660333114e+03 4.6758617978e+04

 982582500: 3.6021819072e+03 1.1544228251e+04

So far, so good.....Then I tried to generate a graph:

/usr/local/rrdtool/bin/rrdtool graph test.gif /
DEF:in=cisco16.1.rrd:ds0:AVERAGE /
DEF:out=cisco16.1.rrd:ds1:AVERAGE /
--start 982578000 --end 982582500

and I get back 0x0, which I can't translate into an error :(

any suggestions?

thanks in advance,
