Basic Concepts and Terminology
The term diagnostics has been used to describe a variety of problem-determination and prevention tools, including exercisers, excitation/response tests, information gatherers, configuration tools, and predictive failure techniques. The focus of the CDM is the enabling infrastructure that describes diagnostic applications and the capabilities of these applications.
The CDM extends the CIM schema to cover the management of diagnostics, including diagnostic tests, executives, monitoring agents, and analysis tools. The objective of diagnostic integration into CIM is to provide a framework in which industry-standard building blocks that contribute to the ability to diagnose and predict the system's health can seamlessly integrate into enterprise management applications and policies.
The diagnostic model also leverages other areas of the CIM model to provide extended diagnostic capabilities rather than introducing diagnostic-centric mechanisms. Examples are the jobs model for monitoring, the log model for capturing information, and effective use of the logical and physical models.

Famous quotes containing the words basic and/or concepts:
“There’s one basic rule you should remember about development charts that will save you countless hours of worry.... The fact that a child passes through a particular developmental stage is always more important than the age of that child when he or she does it. In the long run, it really doesn’t matter whether you learn to walk at ten months or fifteen months—as long as you learn how to walk.”
—Lawrence Kutner (20th century)
“Germany collapsed as a result of having engaged in a struggle for empire with the concepts of provincial politics.”
—Albert Camus (1913–1960)
