# spring-cloud-zipkin-tracing
This project contains samples demonstrating the microservices tracing using zipkin.

## spring cloud sleuth

spring cloud sleuth automatically instruments common communication channels:

* Requests over messaging technologies like Apache Kafka or RabbitMQ (or any other spring cloud stream binder)
* HTTP headers received at Spring MVC controllers
* Requests that pass through a Netflix Zuul microproxy
* Requests made with the RestTemplate, etc.

### zipkin

Distributed Tracing system to trace the request across services in microservices architecture.
