* Time Series Database: Lets you do forecasting and anomalous alerts. Basically lets your alerts have context
* Expression Language so you can manipulate that data: Makes the data you collect and how you alert more orthogonal
* Templating for alerts (Built on Go templates, can include graphs, tables, links, etc)
* IDE interface for developing and alert handling workflow. It also lets you test alerts against history which allows for rapid alert development.
So other than "it does alerting" it is a very different beast from Nagios.
