Maximizing Error Injection Realism for Chaos Engineering With System Calls
IEEE Transactions on Dependable and Secure Computing(2022)
摘要
In this article, we present a novel fault injection framework for system call invocation errors, called
Phoebe
.
Phoebe
is unique as follows; First,
Phoebe
enables developers to have full observability of system call invocations. Second,
Phoebe
generates error models that are realistic in the sense that they mimic errors that naturally happen in production. Third,
Phoebe
is able to automatically conduct experiments to systematically assess the reliability of applications with respect to system call invocation errors in production. We evaluate the effectiveness and runtime overhead of
Phoebe
on two real-world applications in a production environment for a single software stack: Java. The results show that
Phoebe
successfully generates realistic error models and is able to detect important reliability weaknesses with respect to system call invocation errors. To our knowledge, this novel concept of “realistic error injection”, which consists of grounding fault injection on production errors, has never been studied before.
