“I was reading the Swedish computer magazine, Tech
World. There was an article about an appliance solution that could
give a report about unused switch ports. The box PortIQ from
Infoblox costs approximatly 10.000 Euro. op5 has developed this
feature at a customer site and is included with op5 Monitor, op5
has published the code as opensource.“This guide will describe howto get it running in op5 Monitor.
op5 Monitor is vanilla Nagios with some addons so it should be no
problem to follow this guide in a Nagios environment”
