When you're done, restart the Nagios and start collecting data, such as the following tips for about 2 minutes to see the graphical interface.

This graph will have in,out network card traffic, which can be verified on the server Ifstat

in addition, http://nagios.manubulon.com/ This site is also worth a look, there are http://nagios.manubulon.com/check_snmp_int.pl scripts that also enable monitoring of the network
