摘要: Debugging and profiling large-scale distributed applications is a daunting task. We present Friday, system for debugging that combines deterministic replay of components with the power symbolic, low-level simple language expressing higher-level conditions actions. Friday allows programmer to understand collective state dynamics collection coordinated application components. To evaluate we consider several problems, including routing consistency in overlay networks, temporal abnormalities caused by route flaps. show via micro-benchmarks larger-scale measurement can be used interactively debug large under on common hardware.
