Distributed debugging tools for heterogeneous distributed systems

A description is given of a collection of tools that form an implementation of event-based abstraction (EBBA), a paradigm for high-level debugging of distributed systems. The tools are capable of operating effectively in a heterogeneous environment containing processors of varying design and power. Toolset users construct libraries of behavior models and observe the behavior of the system through the models. The toolset is a collection of components that are collectively a distributed system for debugging distributed systems. The components can be combined in varying ways to provide levels of debugging service appropriate for the resources available at individual nodes
