We wrote our own collector in C as this collector is really very small and
just reads UDP packages and writes them nearly as-is into a MySQL database.
BTW: As far as I read mysql is much faster than Oracle. Although Oracle has
of course *many* features still missing in MySQL so it would be worth to
consider using MySQL for netflow and export the then summarized data somewhen
back to the Oracle for further accounting.
The program that calculates free- (two subnets on one router), intern- (i.e.
in our network) and extern-traffic is written in Perl. It takes about 2h
to process the 1-2GB raw data we get per day and gives us per network
statistics.
