I need to monitor the traffic rate in my LAN. I have installed nagios core 3.2 and I can monitor services like CPU load, disk usage, http server, etc. but now, How to monitor traffic?
I am using GNU/Linux Debian Squeeze in all the machines of my LAN.
Switch: Cisco 1900 series
I have tried this tutorial but it refers to files that does not exists in my system (eg. /usr/local/nagios/etc/objects/switch.cfg), I think is because of version.
