Nagios Support Forum

Hello everybody,
I'm trying Nagios for my thesis about Industrial Ethernet network,which is usually a switched Ethernet architecture composed by a PLC, some switches and some remote I/O. I need a tool that allow me to do:

1)Autodiscovery of the devices connect to a LAN(MAC address and IP address).
2)Draw a L2 topology map.I'm using LanTopoLog which reads the forwarding tables of the switch,but I would like to find a tool that has LLDP functionality
3)Bandwith usage for each port of a switch
4)Protocols that are present in each port of a switch.
I' ve seen in this topic https://support.nagios.com/forum/viewto ... ap#p255146 that I cannot achieve point 2. Is it right?
Thanks in advance for your support,
Kind regards,
Alessandro

As @scottwilkerson mentioned, this is possible but you would need to create the map yourself in NagVis.

The only way to get this type of may would be to create it yourself. We have a tool called NagVis included in Nagios XI for creating custom maps

Nagios XI may not be able to do everything you mentioned "out of the box", but will do most of it. You can scan a network via the Auto-Discovery wizard to find devices on the network, and you can run the Network Switch / Router wizard to monitor the status and bandwidth on each port of a switch or a router.
