i'm new to rrdtool - i know that my question has been put in the past at
least for several times and yes i read the tutorial/man pages - and i try to
do the following:
- read each min / 5th min a value, store it in the rrd and get the sum of
all these values for 1 hour.
- create the daily graph (in hour step), the weekly graph (day step), the
monthly graph (week step) and the yearly graph (month step)
- so based on the tutorial i've created the following files and results:

create "test.rrd" --start NOW --step 60 DS:test:GAUGE:120:0.0:U
rrdtool update test.rrd NOW+60:10 NOW+120:0 NOW+180:20 
rrdtool fetch test.rrd TOTAL --start NOW-24*60 --end NOW

the result is NaN for all 24 hours. Why? What did i misunderstood?!
