Abstract

The development and deployment of distributed applications still represents a major problem of computer science due to the complex and heterogeneous architectures of modern computing systems. The goal of this thesis is to improve the development and deployment of distributed applications by enhancing the on-line tool support for heterogeneous middleware environments. Our approach to reach this goal is to provide a monitoring and management system that is tailored to the needs of modern middleware applications. Starting with an analysis of current middleware platforms and on-line tools for various application domains, the shortcomings of existing on-line monitoring and management approaches are worked out. Existing on-line tools mostly represent proprietary solutions for particular middleware platforms and are tailored to homogeneous scenarios, while their monolithic and static architecture limits their flexibility and extensibility. From these insights, several requirements for the development of a monitoring
