would like to use rrd files as 'buffer' for longterm granular data
collection.
and need to be able to store e.g. 4 month worth of 2 minute collections
before i 'export' them into my longterm storage..
(2 weeks would be sufficient, but just playing around currently)

tried to create a rrd file with something like:
rrdtool create 'somefile.rrd' -b-1y -s120 DS:iod:COUNTER:360:0:U
DS:lioqd:COUNTER:360:0:U DS:iodb:COUNTER:360:0:U DS:ioo:COUNTER:360:0:U
DS:ioob:COUNTER:360:0:U RRA:AVERAGE:0.6:1:86400

and was expecting to see 86400 rows when running a 'fetch' without start and
end restrictions.

but i only get around 720 rows...

read the rrdtool tutorials a few times already, 
but seems i'm just not smart enough :(
TIA!
