One RRA is 24 rows, 1 PDP per CDP (with a default of 300 seconds per PDP). The lenght is thus 24*300 seconds == 7200 seconds. The other RRA is 10 rows, 6 PDPs per CDP, 60*300 seconds == 18000 seconds. > rrdtool graph speed.gif \ > --start 920804400 --end 920808000 \ > DEF:myspeed=test.rrd:speed:AVERAGE \ > LINE2:myspeed#FF0000 > Which RRA is used??? Because both RRA are defined with AVERAGE. Could > someone explain this to me? This one is asking for 920808000-920804400 == 3600 seconds. Assuming updates were not made after 920804400 + 300*24 = 920811600, the data will be available in the 1st RRA.
