1 Introduction
Spring Cloud Sleuth is a microservice component in the Spring Cloud ecosystem, used to implement distributed request link tracing (Distributed tracing), which can help developers view the detailed information of each remote call. This article will conduct a detailed analysis of Spring Cloud Sleuth link tracking and give practical cases.
What is Spring Cloud Sleuth?
Spring Cloud Sleuth is an open source Spring Cloud component that provides a distributed request tracing solution. Spring Cloud Sleuth helps developers monitor data interaction behaviors between microservices by collecting and providing log, monitoring, tracking and other data, allowing developers to quickly locate and diagnose microservice faults. Its main functions include the following:
- Service topology diagram
- Request contextual information
- Service dependency diagram
- Error and exception monitoring
- Search and query
- Service tracking statistics
- Use Zipkin or other compatible service discovery mechanism
Why do you need Spring Cloud Sleuth?
Under the microservice architecture, individual microservices are usually deployed in their own independent processes, and communication between them is completed through network protocols. Therefore, when a microservice fails, it becomes very difficult to locate the fault and fix the problem. Spring Cloud Sleuth can help developers easily locate data interaction behaviors between microservices, find root causes and quickly diagnose problems. At the same time, Spring Cloud Sleuth can also provide a complete service topology diagram to facilitate developers to intuitively understand the overall architecture of microservices.
