So, a while back I wrote something I wanted to use for work. It wanted to have something that documents all the different parts in our environment how they are connected. Links to the documentation, infos on how to contact the support team and stuff.
I wanted to have all of this from high level business / information flow point of view, down to a IP, Port, Data Center, Rack detail level.
I started to write a simple status board web app thingy for my own needs. Currently it pulls data from public transport, news feeds, and a weather forecast. There is some basic support for Nagios data in there but that is still work in progress.
