Plug and expand analytics

[knutole]

Refactor analytics

• add CPU load analytics from server side
• add ga.js to webpage, track directly to Google Analytics
• app.log() shortcut
• send user monitoring to slack
• track by using events whenever possible
• track all interactions
• track lots of stuff server side also

Analytics has fallen out, need to plug back into Slack, ga.js.

Also we need a plan for analytics, since we want to track everything anonymously. Google Analytics is perhaps good enough, at least it's powerful. Heap also looks nice, although with a pricetag with > 5000 sessions/month.

We also need to streamline our logging on client-side. Create a separate Wu object for this, which is called from various places in code. Something short, like:

// store on global app
app.analytics = new Wu.Analytics();

// log event with shortcut (see below)
app.log('opened Data Library');

Wu.Analytics = Wu.Class.extend({

   initialize : function () {
       // create shortcut
       app && app.log = this.log;
   },

   log : function (event) {
      var user = app.Accout;
      var user_id = user.getUuid();
      var username = user.getUsername();

      // create message
      var message = username + ' ' + event;

   },

   sendEvent : function () {
       // see api.socket.js, already implemented there.

       // also send to Google Analytics from client
   },
});

Some of this is already implemented. We need to refactor everything and clean it up.

TODO

• plug slack back in
• refactor, clean up existing analytics
• send analytics events to server (websockets)
• send analytics to google
• write tests
