You could try one of the following two approaches:

1)  Try to find an OID that gives you the "load" value (as shown by
    a show interface xxx command).  This will probably be [x/255] so
    you need to do some math on it (multiply by 100, divide by 255).
    I don't know if there is one available and if so, I wouldn't be
    surprised if this would be device and OS dependant.

2)  Use the ifInOctets and ifOutOctets counters.  Divide by the outcome
    of (linkspeed / 100).  You will have to set this value manually or
    write a script that retrieves all three values and returning the
    outcome.

Regards,
