Here is how you can add a new poller as of now (the API may move):

```js
// in plugins/index.js
var myPoller = function() {}; // whatever
myPoller.type = "hello";

exports.initWebApp = function(app) {
  app.get('pollerCollection').add(myPoller); // add the poller to the webapp
};

exports.initMonitor = function(monitor) {
  monitor.pollerCollection.add(myPoller); // add the poller to the monitor
};
```

Before offering a "magic" extension point, we already have to make it powerful. 

As for the UI extension, I'm on it, more to come soon :smile:
