A system, method, and computer readable medium for statistical application-agnostic fault detection of multi-process applications. The computer readable medium includes computer-executable instructions for execution by a processing system. A multi-process application runs on a host. Interceptors collect statistical events and sends said events to a statistical fault detector. The statistical fault detector creates one or more distributions and compares recent statistical event data to historical statistical event data and uses deviation from historical norm for fault detection. The present invention detects faults both within the application and within the environment wherein the application executes, if conditions within the environment cause impaired application performance. The invention also teaches consensus fault detection and elimination of cascading fault notifications based on a hierarchy of events and event groups. Interception and fault detection is transparent to the application, operating system, networking stack and libraries.
