Component-based systems are characterized by the construction of applications through the composition of available software artifacts. Interactions may occur between different components that can be distributed through several machines. As distributed applications increase in size, the interactions between the various nodes that comprise them become more complex. Therefore it is important for distributed component systems to monitor the interactions between components in order to identify failures and bottlenecks in processing and communication. This dissertation presents an architecture capable of offering extensible mechanisms for monitoring the execution environment of distributed components, and the interactions between their components. It also presents a flexible mechanism for publication of the collected information, and some comparative test to measure the performance penalty imposed by the infrastructure to the application.
