config t

int serial x

load-interval 30

Default is 300 seconds or 5 mins

Using show int serial x you should be able to see load on the interface at 30 second intevals.

Check load i.e 255/255 is using 100% 125/255 is 50% utilization.

BTW

A tool you could look at using is mrtg - see www.mrtg.org

The load interval option sould be quickest for you.

thanks for the reply. i was hoping to see if I could see what sort of traffic is actually passing through or at least what protocols are chewing up the bandwidth

If supported by your gateway software and hardware, you can enable NetFlow cache ("ip route-cache flow") on ther serial interface, with or without exporting it to a NetFlow collector:

This will let you get a quick snapshot of the through traffic with "show ip cache flow" on the gateway, or a longer term view on the NetFlow collector/reporting tool.

thats the command I was looking for! thanks a mill
