And you can redraw the mrtg graph as fast as the hardware can run the computations to redraw the pretty graphics. However there are practical limits. What would you rather have the CPU in your hub/switch/router do - run the snmp manager or move packets from one interface to another? most switches and routers I've worked with don't have the CPU power to run the snmp manager at the frequency that you want to have to make it look 'real time' and still do the job they are supposed to be doing. real time output is an illusion here.
