The scheduler pushes messages to the system service every 10 seconds, then the system service broadcasts the messages to any connected clients. You will also learn how to use a JavaScript `WebSocket` object in an HTML file to build a WebSocket connection, subscribe to different events, and display the broadcasting messages from the `system` service in a table.

-The `SystemLoadScheduler` class uses the [hotspot=systemClient file=1]`SystemClient` class to establish a connection to the server by the `ws://localhost:9081/systemLoad` URI at the [hotspot=postConstruct file=1]`@PostConstruct` annotated method. The [hotspot=sendSystemLoad file=1]`sendSystemLoad()` method calls the client to send a random string from either [hotspot=messages file=1]`cpuLoad`, [hotspot=messages file=1]`memoryUsage`, or [hotspot=messages file=1]`both` to the `system` service.
