As parallel program debugging and analysis remain a challenging task and distributed computing infrastructures become more and more important and available nowadays, we have to look for suitable debugging environments to address these requirements. The Debugging Wizard (DeWiz) is introduced as modular and event-graph based approach for monitoring and program analysis activities. Example scenarios are presented to highlight advantages and ease of the use of DeWiz for parallel program visualisation and analysis. Users are able to specify their own program analysis activities by formulating new event graph analysis strategies within the DeWiz framework.
