Spring Cloud Sleuth

Spring Cloud Sleuth is a Log collection toolkit that encapsulates dapper and log-based tracing as well as Zipkin and htrace operations, enabling a distributed tracking solution for Springcloud applications.

First, let's get a few ideas straight.

Zipkin: An open source project on Twitter that allows developers to collect monitoring data on Twitter's services and provide a query interface

The system allows developers to easily collect and analyze data through a Web front-end, such as the processing time of each request service, to easily monitor bottlenecks in the system.

Spring cloud Sleuth with Zipkin, Sleuth integrates Zipkin.

Zipkin is stored in a variety of ways, by default it is stored in memory, but it can not persist, the container restarts and other conditions may result in data loss, in this project, the use of the saved to the MySQL database.

There are two ways to store data in Zipkin and sleuth integration. One is through HTTP, one is through the binding stream, this item is RABBITMQ by binding the message flow.
