Your MaxBytes setting is too low it seems.  Try setting an AbsMax parameter
to something significantly higher or raising your MaxBytes to what is
actually the maximum for what you are monitoring.  If MRTG gets a reading
over what's specified in the MaxBytes setting, it discards it and assumes
its a 0 - unless you have the AbsMax parameter.
