Abstract
Exemplary methods, computer-readable media, and systems describe detecting a performance bug or a nontrivial correctness in a distributed system. The techniques describe using an online predicate checker by specifying a predicate on distributed properties of the distributed system. The process describes monitoring and checking the predicate when the system is deployed and providing a service. In response to detection of the performance bug, the process describes performing modifications of the predicate or installing new predicate.
