摘要:

检测离散事件日志中的异常对于确保系统可靠性、安全性和效率至关重要。传统的基于窗口的日志异常检测方法常常受到上下文偏差和模糊定位的影响,这阻碍了它们精确且高效地识别异常的能力。为了解决这些挑战,我们提出了一个图中心框架TempoLog,它利用多尺度时序图网络进行离散日志异常检测。与传统方法不同,TempoLog直接从事件日志构建连续时间动态图,从而消除了对固定大小窗口分组的需求。通过将日志模板表示为节点,并将其时序关系表示为边,该框架动态地捕获跨多个时间尺度的局部和全局依赖关系。此外,一个语义感知模型通过整合丰富的上下文信息来增强检测能力。在公共数据集上进行的大量实验表明,我们的方法在事件级异常检测中达到了最先进的性能,在准确性和效率方面显著优于现有方法。

英文摘要:

Detecting anomalies in discrete event logs is critical for ensuring system reliability, security, and efficiency. Traditional window-based methods for log anomaly detection often suffer from context bias and fuzzy localization, which hinder their ability to precisely and efficiently identify anomalies. To address these challenges, we propose a graph-centric framework, TempoLog, which leverages multi-scale temporal graph networks for discrete log anomaly detection. Unlike conventional methods, TempoLog constructs continuous-time dynamic graphs directly from event logs, eliminating the need for fixed-size window grouping. By representing log templates as nodes and their temporal relationships as edges, the framework dynamically captures both local and global dependencies across multiple temporal scales. Additionally, a semantic-aware model enhances detection by incorporating rich contextual information. Extensive experiments on public datasets demonstrate that our method achieves state-of-the-art performance in event-level anomaly detection, significantly outperforming existing approaches in both accuracy and efficiency.
