Developing web monitoring applications with Spring

In this recipe, we are going to show you how to build a web application to monitor the server CPU load and memory usage. The server status in the example is sent by a .NET client, but you can expand the example using other languages or operating systems; it's enough to publish a message using the de facto standard JSON protocol—a textual protocol with a very simple grammar (see http://www.json.org/ for the full description). For example, a simple JSON-encoded message looks like the following text:

{"UPDATETIME":"23/06/2013 22:55:32","SERVERID":"1","CPU":10,"MEM":40}

We will introduce Spring Insight now. With Insight, you can monitor the web application's performance and its correct behavior.
