You can close the browser to stop viewing the Dashboard at any time. This does not, however, stop the Dashboard server.
If you are using the Dashboard application (Section 3.24.3, “Using the Dashboard locally: Starting the Dashboard with default parameters and automatic browser opening”) you can stop the Dashboard server by right-clicking on the system tray icon and selecting ”Exit”.
If you started the Dashboard server (Section 3.24.4, “Using the Dashboard over the network: Starting the Dashboard server with custom parameters”), then you can stop the Dashboard server by killing the process.
