GoTcha: An Interactive Debugger for GoT-Based Distributed Systems
Debugging distributed systems is hard. Most of the techniques that have been developed in both research and industry for debugging such systems use either extensive model checking, or postmortem analysis of logs and traces. Interactive debugging is typically a tool that is only effective in single threaded applications, and is rarely applied to distributed systems. While the live observation of state changes using interactive debuggers is effective, it come with a host of problems. In this paper, we discuss the requirements an interactive debugger for distributed systems should meet, the role the underlying distributed model plays in facilitating the debugger, and the implementation of our interactive debugger: GoTcha.
GoTcha is a browser based interactive debugger for distributed systems built on the Global Object Tracker (GoT) programming model. We show how the GoT model facilitates the debugger, and the features that the debugger can offer. We also demonstrate a typical debugging workflow.
