Autonomic control of a distributed computing system using rule-based sensor definitions

摘要

A distributed computing system conforms to a multi-level, hierarchical organizational model. One or more control nodes provide for the efficient and automated allocation and management of computing functions and resources within the distributed computing system in accordance with the organization model. A user, such as a system administrator, interacts with the control nodes to logically define the hierarchical organization of distributed computing system. The control node includes an automation subsystem having one or more rule engines that provide autonomic control of the application nodes in accordance with a set of one or more rules. For example, the rules may define sensors or methods of configuring the distributed computing system. More specifically, the sensor rules define the conditions under which the automation subsystem may update a model of the distributed computing system based on data received from the distributed computing system.
