[rrd-developers] Re: Feature status/requests - sub second resolution & 'relative' time

[Stanislav Sinyagin]

Hi Pete,

out of topic, but I really wonder why you'd really need to put such 
data into RRD. If that's for graphing only, you could utilize Gnuplot, 
or probably hack RTG (http://rtg.sourceforge.net), since it uses SQL 
storage as backend.

RRDtool is excellent in processing periodically updated data series,
but IMHO for single 10-minute shots it seems to be the wrong tool.

regards,
Stan
