Hi Sven,
rrdtool fetch will use the data which
a) covers the timerange you requested
b) has a higher or equal resolution to what you requested ...

If I keep averages say over 10 and 30 seconds:
RRA:AVERAGE:0.5:10:360
RRA:AVERAGE:0.5:30:240

Hi Alex,
I am not sure about your question. Are you asking why I want to fetch data
with arbitrary time resolutions?
It is interesting to see dynamics of network characteristics in different
timescales. RRD file can store statistics in only a limited set of time
resolutions, which are fixed and c
