If you want realtime insight into user behaviour, statsd[1] might work for you. It's what Etsy uses[2] to send tracking data to Graphite[3], a realtime graphing system. Graphite is a bit ugly, so Paperless Post wrote a nice front end for it, named Graphiti[4].<div>

I've been tasked with creating a user activity tracking engine, in order to build more complete profiles on our users, their preferences and common activities. </div><div style="font-size:14px;font-family:Calibri,sans-serif">
<br></div><div style="font-size:14px;font-family:Calibri,sans-serif">But I'm not really sure in which direction to go, I'm pretty sure that it's got to be a separate app, with a fast write database, something like MongoDB perhaps. Along with an exposed REST API to post and retrieve data.</div>
