中文摘要: 在云平台的运行维护中, 虚拟化环境的故障定位对容错极其重要. 针对虚拟化环境的空间拓扑时变性, 提出了一种基于时变的节点间依赖关系的日志分析方法, 为决策树故障定位提供支持. 节点间依赖关系能够帮助压缩日志, 只提供故障时间窗口内的有效信息作为挖掘来源, 从而更快更准确地完成故障定位. 实验表明, 能够在较大系统规模的多变的虚拟化环境下实现有效和高效的故障定位.
Abstract:Fault localization is extremely important for fault tolerance in Virtualization-based cloud platform. This paper proposes an inter-node dependency-based log analysis approach consider the time-varying spatial topological using decision tree. Dependencies between nodes can help compressing log, providing valid information for analysing, thereby completing the fault localization faster and more accurately. Experiment results show that our approach can help to achieve effective and efficient fault localization in the larger-scale virtual environment variable.
