The System Status function is provided for you to show messages to your Users at run-time if something important has happened to the system or server they need to know about.
Messages can be Success (by default green), Warning (amber), Error (red) or Info (blue). Clicking the button will display the message.
You can provide default and start-up messages (and message types) and also choose whether an Alert will be displayed when the System Status changes (to anything other than default).
You can set the System Status through Dashboard State and see the System Status in 3 ways: via the System Status button in the Home Toolbar or via the System Status toolbar and tool panel.
