Monitoring Distributed Systems

The improvement of computer systems and the progress in network technologies has lead to an intensified: decentralization of services and datas utilization of common resources (e.g. network) parallelization of processing steps in application systems The partitioning of the application system into a distributed application system allows a good adaption of the system on physical, organizational and softwaretechnical requirements. A consequence of this development could be a increasing demand of distributed application systems. During development of a distributed application systems, developers are confronted with problems, which do not exists for the development of centralized systems, or exists only in a restricted form. Examples for such problems are the distribution of resources and/or processes to multiple computers, the parallelization of processing steps, the identification and treatment of failures, the steering of the processing of asynchronous events and the integration of communications services. >Monitoring< and dynamic program analysis shall help to support the development of distributed application systems. Major concerns are the fulfilment of system requirements, the coverage of problems as mentioned above and the observation of running systems. This project includes the development of a online monitoring environment for distributed object-oriented applications. The monitoring environment is based on a distributed object-oriented software infrastructure (ObjectWire)......
