分布式系统的可观测性建设

Observability construction of distributed systems

分布式系统,是由一组通过网络进行通信,为了完成共同任务而协作的计算机节点组成的系统。与传统单体系统相比,分布式系统在体系架构方面有较大不同,对配套的运维能力特别是可观测能力也有更高要求。文章描述了分布式系统的可观测性建设思路,从应用本身以及IT基础设施2个层面进行建设,首先需要对分布式系统进行建模,其次从性能指标、运行日志、可追踪链路3个维度建立监测标准,统一技术语言,最后完成监控系统整合,并与周边系统集成,以完成分布式系统的可观测性建设。

A distributed system,which is a group of computer nodes that communicate through a network and write in order to complete a common task.Compared with traditional single systems,distributed systems are quite different in terms of architecture,and have higher requirements for supporting operation and maintenance capabilities,especially the observable capabilities.This paper describes the observability construction ideas of distributed system,from the application itself and IT infrastructure two levels,the first need to model the distributed system.
