If I do a show int on my router it shows the following:
75344074 packets output, 707884711 bytes, 0 underruns
How do i figure out how much traffic is really going throough the interface?
I thought if you dropped the last 6 numbers of the number that shows as bytes that this would do it for me but the number does not make sense since the card is only capable of 45 Meg.
I tried a converter but that number did not make sense either.

Those numbers represent the total amount sent since last restart or clearing of counters.About 675gig if my maths correct.
To get an average speed/bit rate you can look at
5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec
Or simply take note of the byte count at one point in time and then at a later take it down again, then calculate the average usage over that time.
I would suggest you have a look at a free product called Cacti.
You install it on a linux server and then add devices and interfaces to be polled.
It then can generate graphs of line usage, error rates and some other information.
It can also graph cpu usage over time.
Its a really good tool to keep track of trends in line and cpu usage.
