Devmon / MRTG

Hi,

Could I get a quick-and-dirty explanation regarding the Devmon implementation in Xymon 4.3.x?

The way I understand it, Devmon provides SNMP capabilities to Xymon so the monitoring server can poll SNMP capable devices.

How is this different to Integrating MRTF data into XYMON, for example?

If I am interesting in getting bandwidth for various device interfaces, I am assuming it is best to do via Devmon rather than integrate MRTG?

Lastly, is there a readme / howto that explains devmon-xymon setup?

Thanks, Mario
