Online failure prediction approaches aim to predict the manifestation of failures at runtime before the failures actually occur. Existing approaches generally refrain themselves from collecting internal execution data, which can further improve the prediction quality. One reason behind this general trend is the runtime overhead incurred by the measurement instruments that collect the data. Since these approaches are targeted at deployed software systems, excessive runtime overhead is generally undesirable. In this work we conjecture that large cost reductions in collecting internal execution data for online failure prediction may derive from pushing the substantial parts of the data collection work onto the hardware. To test this hypothesis, we present a lightweight online failure prediction approach, called Seer, in which most of the data collection work is performed by fast hardware performance counters. The hardware-collected data is augmented with further data collected by a minimal amount of software instrumentation that is added to the systems software. In our empirical evaluations conducted on three open source projects, Seer performed significantly better than other related approaches in predicting the manifestation of failures.
