Logging and tracing are usually not very important during development, but these are the key features that are used in the maintenance of the system. In this chapter, I have placed emphasis on the fields of development and operations. I have shown you how to integrate a Spring Boot microservice application with Logstash and Zipkin in several ways. I have also shown you some examples to illustrate how to enable Spring Cloud Sleuth features for an application in order to make it easier to monitor calls between many microservices. After reading this chapter, you should also be able to effectively use Kibana as a log aggregator tool and Zipkin as a tracing tool for discovering bottlenecks in communication inside your system.
Spring Cloud Sleuth, in conjunction with Elastic Stack and Zipkin, seems to be a very powerful ecosystem, which removes any doubts you might have about problems with monitoring systems that consist of many independent microservices.
