Monitoring Hardware Components
One of your responsibilities as a system operator is to understand how your system is
configured so you can check that the hardware and software associated with it are in

As a standard for what is normal in your operating environment, it is helpful to have
copies of:
System configuration diagrams of your particular system (see the example in
