[mrtg-developers] Consolidation algorithm?

We use MRTG without rrdtool, just with rateup, to produce graphics from
several routers. Now we would like to produce a log from the logs. This
log should be a mini log showing stats only for months.
I know that rateup uses a consolidation algorithm to produce the logs. Is
it possible to use that consolidation algorithm to create another log with
values by month? What are the consolidation functions?
I am not used to network development and it is dificult to me to deduce how
are created the values in the logs.
How are calculated the values: average incoming transfer, average outgoing
transfer, maximum incoming transfer and maximum outgoing transfer? May I
use those values to create a log file with only month values?
I've been reading trough the code, but it is dificult to me to understand
Also I have tried to build rateup with Visual C++ 6.0 to run it in debugging
mode to figure out the algorithm but I have these errors:
LINK : warning LNK4098: defaultlib "LIBCMT" conflicts with use of other
libs; use /NODEFAULTLIB:library
rateup.obj : error LNK2001: unresolved external symbol _gdImagePng
Debug/rateup.exe : fatal error LNK1120: 1 unresolved externals
I linked with libgd.lib from the one used to build php. Maybe this is where
I am wrong in building.
Please, any help will be appreciated.
