1. A management system for generation of a management object model including a structured hierarchy of objects representing hardware components of a computer system for performing management of the computer system, the management system comprising: a processor; and a memory coupled to the processor, wherein the memory comprises program instructions configured to implement: component modules operable to define mappings from instrumentation of the hardware components to objects representing those hardware components, wherein one of said component modules for a hardware component identifies an instrumentation module defining a source of instrumentation for the hardware component, and wherein the instrumentation module comprises a general part and a specific part, the general part being operable to communicate with the specific part via a private interface to obtain instrumentation data, and the specific part being configured to interface with instrumentation for the hardware component to obtain said instrumentation data; and configuration modules operable to configure associations between the component modules for the generation of the management object model.
