MRTG and Cacti are different products, and may use different Nagios plugins.

MRTG creates a website, puts the logs in that website's directory, and
dynamically creates graphs based on the log data.  On my Ubuntu
Nagios/MRTG machine, the logs & web pages are in /var/www/mrtg.

Each port gets its own log, so for instance on my switch 10.5.10.4,
port 15, the log file is:

nagios at itweb1:/var/www/mrtg$ ls -l 10.5.10.4_15.log
-rw-r--r-- 1 root root 74442 2011-05-04 15:40 10.5.10.4_15.log

and the service bandwidth check in Nagios is:

define service{
        use                     generic-service ; Inherit values from a template
        host_name               switch-CoreA
        service_description     Port15
        check_command
check_local_mrtgtraf!/var/www/mrtg/10.5.10.4_15.log!AVG!1000000,1000000!5000000,5000000!10
        }

I haven't used Cacti, so can't offer tips there.
