Hi there,

I have a couple of questions, first of all my base rrdtool command is:
...
--step 60
DS:trafficOUT:COUNTER:120:0:U
DS:AvgTrafficOUT:COMPUTE:trafficOUT,8,*
RRA:AVERAGE:0.5:1:1440
...

I want to know if there is a command wich returns the number of days
from the start. I want to use it with the COMPUTE command.
The second question is, how can I make a variable with auto-increase?, i
mean, to do something like: DS:num:COMPUTE:num,1,+

Thanks in advance!
