The real beauty of Spring Cloud Sleuth is seen when it’s combined with logging aggregation technology tools such as Papertrail (http://papertrailapp.com) and tracing tools such as Zipkin (http://zipkin.io). Papertail is a cloud-based logging platform used to aggregate logs in real time from different microservices into one queryable database. Open Zipkin takes data produced by Spring Cloud Sleuth and allows you to visualize the flow of your service calls involved for a single transaction.

Zipkin (http://zipkin.io)—Zipkin is an open source data-visualization tool that can show the flow of a transaction across multiple services. Zipkin allows you to break a transaction down into its component pieces and visually identify where there might be performance hotspots.

This is where Spring Cloud Sleuth and the OpenZipkin (also referred to as Zipkin) project shine. Zipkin (http://zipkin.io/) is a distributed tracing platform that allows you to trace transactions across multiple service invocations. Zipkin allows you to graphically see the amount of time a transaction takes and breaks down the time spent in each microservice involved in the call. Zipkin is an invaluable tool for identifying performance issues in a microservices architecture.

Setting up Spring Cloud Sleuth and Zipkin involves four activities:
