基于程序分析的分布式应用自动化追踪方法

Auto-Tracing in Distributed Applications Based on Program Analysis

提出了一种零配置的端到端细粒度追踪的方法—Easy Trace,应用于分布式系统发生性能降级时的问题诊断.传统工具往往存在监测粒度与服务组件源码紧耦合或配置信息复杂、修改代价高等不足,Easy Trace能够做到零配置下性能问题的准确定位.基于开源电子商务系统的实验结果表明,Easy Trace相对传统监测工具对系统造成的扰动很小.

A zero-configuration fine-grained end-to-end tracing approach, namely Easy Trace, is proposed, which is applied to the diagnosis of distributed system with performance degradation problem. Compared with the traditional tracing tools, in which granular control and service component source code are tightly coupled or which have complex configuration and high cost of modification, Easy Trace achieves accurate performance problem locating in the premise of zero-configuration. Extensive experiments that use Easy Trace to trace an open source e-commerce system show that compared with traditional monitoring tools, the disturbance caused by Easy Trace is low.
