摘要:

软件密集型系统生成日志用于故障排除目的。最近,已经提出了许多深度学习模型来基于日志数据自动检测系统异常。这些模型通常要求非常高的检测精度。例如,大多数模型在常用的HDFS数据集上报告的F测量值大于0.9。为了深刻理解我们距离解决基于日志的异常检测问题还有多远,本文深入分析了五种最先进的基于深度学习的模型,用于在四个公共日志数据集上检测系统异常。我们的实验集中在几个方面的模型评估,包括训练数据选择,数据分组,类分布,数据噪声,早期检测能力。我们的研究结果指出,所有这些方面的评价有显着的影响,并不是所有的研究模型都能很好地工作。基于日志的异常检测问题尚未得到解决。根据我们的研究结果,我们还提出了未来可能的工作。

英文摘要:

Software-intensive systems produce logs for troubleshooting purposes. Recently, many deep learning models have been proposed to automatically detect system anomalies based on log data. These models typically claim very high detection accuracy. For example, most models report an F-measure greater than 0.9 on the commonly-used HDFS dataset. To achieve a profound understanding of how far we are from solving the problem of log-based anomaly detection, in this paper, we conduct an in-depth analysis of five state-of-the-art deep learning-based models for detecting system anomalies on four public log datasets. Our experiments focus on several aspects of model evaluation, including training data selection, data grouping, class distribution, data noise, and early detection ability. Our results point out that all these aspects have significant impact on the evaluation, and that all the studied models do not always work well. The problem of log-based anomaly detection has not been solved yet. Based on our findings, we also suggest possible future work.
