>From this we cannot see how your rrd database was built. Do a rrdtool info <filename.rrd>, you'll see something like this:
step = 300 rra[0].rows = 599 rra[0].pdp_per_row = 1 rra[1].rows = 700 rra[1].pdp_per_row = 6 rra[2].rows = 775 rra[2].pdp_per_row = 24 rra[3].rows = 796 rra[3].pdp_per_row = 288 rra[3] covers rows * pdp_per_row * step = 796 * 288 * 300 seconds. That is the longest time for which the rrd database will hold data. Does you largest rra cover more than 4 hours?
