In service management, there is a need to evaluate the quality of service of a service type object or the performance of a server object. This management function provides the capability for a manager to evaluate such managed objects. introduces a managed object class called the objectEvaluator. An object evaluator encapsulates the evaluation function which is used to evaluate a given managed object on a periodic basis. Our work here is motivated by our current works to define management ensembles for service management in an enterprise environment. In an enterprise environment, an enterprise manager needs tools to add intelligence to its agents. This Object Evaluator Management function can serve as one of those tools. It provides the capability for to encapsulate an an enterprise manager instruction set in an object evaluator. The agent can use the instruction set to perform a function evaluation on a periodic basis. Although health evaluation is the primary motivation of our paper, the evaluation function can be also used to execute a non-performance related task, as long as there is a need to execute the task in a periodic basis. This delegation of evaluation responsibility to an agent can substantially simplify the task of an enterprise manager.
