Failure diagnosis in practical systems is difficult, and the main obstacle is that the information a developer has access to is limited. This information is usually not enough to help developers fix or even locate the related bug. Moreover, due to the vast difference between the development and production environments, it is not trivial to reproduce failures from the production environment in the development environment. When failures are caused by non-deterministic events such as race conditions or unforeseen inputs, reproducing them is even more challenging.
