Bosun really is different in many ways than Nagios. There are 4 major components that are a the root of Bosun: * 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.
