A script I developped that pulls information out of Nortel routers and switches via snmp and shows it on a webpage. For more info click here.
Almost two years ago I uploaded some nagios plugins to nagiosexchange.com, nowadays monitoringexchange.com. I make the downloads available via my own website too so if you are looking for some plugins these might be handy. They are available for download here. Enjoy! And leave a reply if you use them, I'd much appreciate that :)
