Hi All, Ok, it's been some time since I visited rrdtool, and I was going to make an rrd to store my temperatures. So I got into deciding what I needed for archives, and I think I've just confused myself.
If I wanted to store temperature data for say 2 years. Taking a temperature reading every half hour. I got to thinking, wouldn't I just need one RRA? Namely: RRA:AVERAGE:0.5:1:17520 where 17520 is the number of half-hours in a year? But to me this just doesn't look right. I think I'm missing the entire concept or RRA's here..While I think this would work to give me my half-hour readouts for a year, do I need an RRA for each "level" of read-outs I want, ie, a daily RRA, a weekly RRA, a montly RRA and a yearly RRA? But doesn't rrdtool figure this out anyway when I go to graph it? I've read the documenation on-line, but still am confused as to why I'd need more than one RRA:AVERAGE statement for my data I guess is the bottom line. I realize I've completely rambled on here, my apologies. I've simply confused myself here! Any help is greatly appreciated.
