Monitoring and Visualizing Software-heterogeneous Distributed Object Applications

Distributed applications composed of many cooperating components, written in diierent computing environments , that will become more common in the near future, increase substantially demands for monitoring and visualization tools. Complexity and the non-deterministic nature of such programs cause that information about them is diicult to manage, store, and visualize. In this paper solutions to these problems and methods of dynamic behaviour visualization of software-heterogeneous applications employed in MODIMOS monitoring system are presented.
