Abstract

A critical business requirement of today's enterprise applications is automated debugging of violation of Service Level Objectives (SLOs). However, the increasing scale and complexity of these systems present various challenges in building such solutions. This problem becomes challenging mainly because of two reasons: (1) availability of large number of metrics that can potentially be the causes, (2) availability of large number of data-points. The existing techniques are either highly compute-intensive and thus are not viable for use on large volumes of data or compromise on accuracy. To successfully balance these two objectives simultaneously, we propose to intelligently prune the search space. We apply feature selection to remove irrelevant and redundant metrics. We then identify temporal regions of interest to narrow down the analysis to a smaller set of data-points. We present a comparative study of the proposed approach with other existing approaches through experimental evaluation.
企业系统中SLO违规的自动调试
当今企业应用程序的一个关键业务需求是自动调试违反服务水平目标(Service Level Objectives, slo)的情况。然而,这些系统日益增长的规模和复杂性在构建此类解决方案时提出了各种挑战。这个问题变得具有挑战性主要是因为两个原因:(1)大量度量的可用性可能是潜在的原因,(2)大量数据点的可用性。现有的技术要么是高度计算密集型的,因此不适合用于大量数据,要么在准确性上有所妥协。为了同时成功地平衡这两个目标,我们建议对搜索空间进行智能修剪。我们应用特征选择来去除不相关和冗余的指标。然后,我们确定感兴趣的时间区域,将分析范围缩小到更小的数据点集。我们提出了一个比较研究提出的方法与其他现有的方法通过实验评估。
