There are different ways for achieving this, I looked at 3 tools before setting up our system: <ol><li>MRTG : Easy to configure, plugin for generating alarms available in the nagios default plugins, bad visualization (static html pages) </li><li>Cacti: Good visualization, difficult integration to nagios, graphic configuration difficult to automate. </li><li>check_snmp_int + pnp4nagios: Excellent visualization (zoom, pdf generation and calendar in pnp4nagios). Stable plugin with support for regular expressions for selecting interfaces. </li></ol>All the options will give you a good overview of the bandwidth usage. I use the 3rd one since the integration to nagios is simple and the visualization is very good. Both pnp4nagios and check_snmp_int are available in the nagios exchange site.
