Most Internet services (e - commerce, search engines, etc.) suffer faults. Quickly detecting these faults can be the largest bottleneck in improving availability of the system. We present Pinpoint, a methodology for automating fault detection in Internet services by : 1) observing low - level internal structural behaviors of the service ; 2) modeling the majority behaviour of the system as correct ; and 3) detecting anomalies in these behaviours as possible symptoms of failures. Without requiring any a priori application -specific information, Pinpoint correctly detected 89 % - 96 % of major failures in our experiments, as compared with 20 % - 70 % detected by current application - generic techniques.
