Close, but no cigar!
You probably do not want 1 minute averages for 732 days. If so, you just need
the last RRA and skip the rest.
Else, make it for instance:
For 2days/2h,
1 minute averages
(50hrs * 60 min) / 1 min = 3000 points
For 12.5days,
5 minute averages
(300hrs * 60) / 5 min = 3600 points
For 50days,
30 minute averages
(1200hrs * 60) / 30 = 2400 points
For 732days,
4 hour averages
(17568hrs * 60) / (4 x 60) = 4392 points
The number of rows is the number of consolidated data points.

Subject: [rrd-users] Storing data once a minute
Hello,
I need to write data in an RRD databse every minute. I've done the
calculations, but would like a "rrd veteran" to double check my answer. Any
suggestions or help is greatly appreciated.
For 2days/2h, 50hrs*60 = 3000 points
For 12.5days, 300hrs*60 = 18000 points
For 50days, 1200hrs*60 = 72000 points
For 732days, 17568hrs*60 = 1054080 points
when I setup up the archive it should look like:
"--step=60",
"DS:input:GAUGE:120:U:U",
"DS:output:GAUGE:120:U:U",
"RRA:AVERAGE:0.5:1:3000",
"RRA:AVERAGE:0.5:30:18000",
"RRA:AVERAGE:0.5:120:72000",
"RRA:AVERAGE:0.5:1440:1054080"
Thanks,
Mike
