Built with Ruby, Sinatra, Faye, Redis, and D3.JS
Faye runs as Rack middleware, Sinatra handles initial HTTP request/serving of client assets (which uses D3.JS for visualization). Redis holds on to the monitoring data in a TRIM'd List.
Mostly just a quick experiment to get more familiar with the technologies listed above.
