Using Graphical Status Monitors
The graphical status monitoring tools described in this chapter are also referred to as enterprise management frameworks. These tools monitor multiple systems from a central location and display status information graphically.

Besides, even if the console or front panel doesn't indicate any problems, network problems can make the system inaccessible to the end-user. Graphical status monitors can detect connectivity problems because they rely on network polls to gather status information.
