Showing stats with collectd + d3js

Install dependencies:

1. Install rrdtool. On Mac, homebrew works. On Linux, use apt-get install rrdtool, apt-get install librrd-dev. On Windows, figure this out yourself (and add instructions here). Make sure rrdtool is on the path (try $which rrdtool, $rrdtool).

2. Get node dependencies:

    $cd node
    $npm install
   

Unit tests

• by npm (a script is configured in package.json)
