DC-Prophet: Predicting Catastrophic Machine Failures in DataCenters

摘要

When will a server fail catastrophically in an industrial datacenter? Is it possible to forecast these failures so preventive actions can be taken to increase the reliability of a datacenter? To answer these questions, we have studied what are probably the largest, publicly available datacenter traces, containing more than 104 million events from 12,500 machines. Among these samples, we observe and categorize three types of machine failures, all of which are catastrophic and may lead to information loss, or even worse, reliability degradation of a data-center. We further propose a two-stage framework-DC-Prophet (DC-Prophet stands for DataCenter-Prophet.)-based on One-Class Support Vector Machine and Random Forest. DC-Prophet extracts surprising patterns and accurately predicts the next failure of a machine. Experimental results show that DC-Prophet achieves an AUC of 0.93 in predicting the next machine failure, and a F_3-score (The ideal value of F_3-score is 1, indicating perfect predictions. Also, the intuition behind F_3-score is to value "Recall" about three times more than "Precision" [12].) of 0.88 (out of 1). On average, DC-Prophet outperforms other classical machine learning methods by 39.45% in F_3-score.
