I see what you are saying and this makes sense, but how do you work
out the seconds for a month as a month could contain between 28 and 31
days - or does rrdtool treat all months as 28 days?
Also, if I don't have a full month worth of data then I will be
over-calculating the total?

I am liking this function and I have the following:
DEF:ifInOctets=<RRD>:ifInOctets:MAX
VDEF:ifInOctetsTotal=ifInOctets,TOTAL
PRINT:ifInOctetsTotal:\'%6.1lf %sB\'
I am storing RRA's with both MAX and AVERAGE CF functions as users
like to be able to see the peaks as well as the averages.
I have read the man page for TOTAL, but I am still slightly confused -
does it use the same theory as above (e.g. multiply the value by the
amount of seconds)? Also, if I don't have a full weeks worth of data,
could it over-calculate?
For this to be accurate I am assuming I really need to use the AVERAGE
DS as opposed to the MAX DS or my values will be too high?
Thanks,
Chris
