MRTG reads information given to it.

A Cisco usually keeps counters. MRTG reads the difference between two
counters at an interval of 5 minutes, and calculates the amount of bps
according to that.

Have a look at this:

WithPeak

       By default the graphs only contain the average values of
       the monitored variables - normally the transfer rates for
       incoming and outgoing traffic.  The following option
       instructs mrtg to display the peak 5 minute values in the
       [w]eekly, [m]onthly and [y]early graph. In the example we
       define the monthly and the yearly graph to contain peak as
       well as average values.

       Examples:
