As far as I know it has to do with the RRD create parameters.
I would suggest that you digg in the documentation of RRD especially the create command.
It is possible but will require to remove your current rrd files.
And it also will have a bigger filesize ofcourse.
I'm not good in this stuff, but I thought this is close to reality.
There is a RRA called AVERAGE which is defined like:
Store the AVERAGE value over a period of 1 cycles 600 times
if your cycle time is 300sec then you will store every 5min the value and this 600 times so:
Store every 5 min a value for 50 hours
Store the average value over 30 minutes for 12,5 Days
Store the average value over 2 hours for 50 days
Store the average value over 24 hours for 600 days
So as you can see to more time elapses the more the values will be averaged.
Now you could say you want to store the 5 min value for 30 days by changing the first RRA to:
( 30 days * 24 hours * 60 minutes) / 5 minutes cycle time = 8640
If i'm mistaken please let me know
