[rrd-users] Re: Weekgraphs shows only one day.

[Stephan Harren]

You'll have to do it like this:

RRA:AVERAGE:0.5:1:576
RRA:AVERAGE:0.5:6:384
RRA:AVERAGE:0.5:24:384
RRA:AVERAGE:0.5:288:366

1st line means that you save 576 initial values.
2nd line means that you save 384 values averaged from 6 initial values.
3rd line means that you save 384 values averaged from 24 initial values.
4th line means that you save 366 values averaged from 288 initial values.

(certainly, numbers of saved values are changeable)

Dump your rrd with rrdtool dump <rrdfile> and take a look at it, this 
will make things more clear. If you create an rrd, it is created to have 
a defined number of values, they are filled up with NaNs and this number 
won't change any more. What you did is, you defined your AVERAGE 
data-source to save 288 5-minute values and that's it.

HTH,
