Your RRA holds 1461 samples, each sample calculated by taking the average of 288 consecutive inputted values. If more than 30% (0.3 x 100%) of those 288 values are the unknown, the sample becomes unknown. Otherwise the sample becomes the average of all known values of the 288 values. > ------------------------------------------- > rrdtool create target.rrd > --start 1023654125 > --step 10 > DS:mem:GAUGE:300:0:671744 > RRA:AVERAGE:0:1:288 > RRA:AVERAGE:0.3:6:1440 > RRA:AVERAGE:0.3:72:1460 > RRA:AVERAGE:0.3:288:1461 > --------------------------------------------- > > RRA:AVERAGE:0:1:288 > my interpretation:: > the data will be saved every 10 seconds for 288 rows, > which means the graph is saved for (288*10) / (60sec/min) = 48 mins. Correct. and > RRA:AVERAGE:0.3:6:1440 holds 6 x 1440 x 10 / 3600 = 24 hours of data in 1 minute samples.
