Diagnosing missing events in distributed systems with negative provenance
2014
Proceedings of the 2014 ACM conference on SIGCOMM - SIGCOMM '14
When debugging a distributed system, it is sometimes necessary to explain the absence of an event -for instance, why a certain route is not available, or why a certain packet did not arrive. Existing debuggers offer some support for explaining the presence of events, usually by providing the equivalent of a backtrace in conventional debuggers, but they are not very good at answering "Why not?" questions: there is simply no starting point for a possible backtrace.
