First of all I have to say I'm a complete newbie on Nagios. I have to make a large work which involves Nagios and there's something I need to make clear.
My question is: which protocols can Nagios collect and analize? I guess SNMP won't be a problem, but I'd like to know if it can also work with RMON, SFLOW and NETFLOW. If routers/switches send information using these protocols, will Nagios be able to treat and analize them?
