Finally, experiments containing successful fault injections are used to estimate the specified measures. Once faults are injected, a post-runtime analysis, using off-line clock synchronization, is used to place events and injections on a single global timeline and to determine whether the intended faults were properly injected. ![]() In Loki, fault injection is performed based on a partial view of the global state of a distributed system, i.e., faults injected in one node of the system can depend on the state of other nodes. This complicates the validation of such systems via fault injection, since it suggests that faults should be injected based on the global state of the system. Distributed applications can fail in subtle ways that depend on the state of multiple parts of a system. Loki is a global state-driven fault injector for distributed systems. Loki was a crafty Norse trickster god who delighted in creating uproar through mischievous pranks.
