1. A method of evaluating a computer system comprising the steps, executed by a modeling data processor, of:
- producing a model of a configuration representing physical devices in the computer system, connections of the physical devices in the computer system, and workloads which are processes that use system resources provided by the physical devices of the configuration of the computer system in the data processor;
displaying, on a visual display device coupled to the modeling data processor, a diagram representative of the configuration of the computer system;
modifying the configuration of the computer system to provide a modified configuration in response to an input to modify;
modifying the model of the computer system in accordance with the modified configuration of the computer system;
determining new values of selected metrics for the modified model of the computer system, with said selected metrics including measurable values representative of a performance characteristic of the computer system; and
displaying on the visual display device a diagram of the modified configuration of the computer system.

Abstract
A modeling system provides a display of a computer system'"'"'s configuration along with selected system metrics. An operator can change the configuration by using the display and display commands. Metrics representative of the performance of the computer system would then be determined for the changed configuration, and could presented along with the display of the new system configuration.
