....of estimating (monitoring and tracking) deciding and acting. Observation variables capture the relevant aspects of the status of the system, and are provided by sensors. Sensor in this work also includes other awareness mechanisms such as monitoring by dedicated components in the middleware [3][4] 8] in the operating system [10] and in the application managers. These techniques are necessary to capture system level measures such as throughput, CPU utilization, and average delay, and environment parameters such as subsystems used by a response, levels of competitive workloads. Failure ....

Sensor in this work also includes other awareness mechanisms such as monitoring by dedicated components in the middleware[4] [6] 13] in the operating system [19] and in the application managers.

....can be found in the literature. For example, detailed descriptions of the four meta models can be found in [Costa00a] 3 Modeling Resources for Middleware 3. 1 Resource Model The most important elements of the resource model are abstract resources, resource factories and resource managers [ReTINA99, Blair99b, Duran00a, Duran00b]. Abstract resources explicitly represent system resources. In addition, there may be various levels of abstractions in which higher level resources are constructed on top of lower level resources. Resource managers are responsible for managing resources, that is, such managers either map or ....

....main elements of the resource model. Importantly, virtual task machines (VTMs) are top level resource abstractions and they may encompass several kinds of resources (e.g. CPU, memory and network resources) allocated to a particular task. Further details regarding the resource model can be found in [Blair99b, Duran00a, Duran00b]. 2.3 The Task Model The main feature of the task model is that it offers a high level of resource management by modelling coarse grained interactions. That is, a task may spawn the boundaries of a component and even those of an address space. We define tasks from two points of view. From the ....
