One of the benefits of working in IT is that there is typically a healthy supply of miscellaneous, half-functioning equipment to mess around with. [Vittore] had an old laptop with a busted LCD sitting around (Google Translation), so he figured he might as well get it to do something useful. With a spare desktop LCD panel and some software tweaking, he built himself a slick network monitoring panel that hangs in his office.
He stripped the laptop down to the bare essentials, and mounted it along with an LCD screen in a plexiglass enclosure. He has Nagios running a server in his office, and with the help of a few plugins, he created a simple web interface that show him the topology of his entire network. The panel itself runs a live version of Debian, which he configured to load up his Nagios web page each time it is started.
While having the ability to view the status of every network-connected device in an instant is great, he didn’t stop there. While browsing around online, he found diagram for a simple USB-based performance monitor that uses a PIC to drive a pair of VU meters. He hooked the meters up to a router monitored by Nagios, so he can watch office’s bandwidth usage in real time.
