Distributed tracing is must have when we create our microservices . Frameworks like Spring Boot,Micronaut comes with the support of creating TraceId,SpanId and propagate to visualization tools like Zipkin,Jaegar . This post shortly describe what we need to add in order to log the TraceId in application or access log . Logging traceId helps us in correlating the logs . For logging I have used Slf4j with logback . In micronaut support for generating TraceId comes quite easily just matter of adding proper dependencies which can be found here https://guides.

Adoption of microservices architecture is on rising. Teams reap benefits of microservices which enables them to deliver faster, chose a language stack for their choice, quick feedback cycle, etc but, this freedom and pace comes at the cost of complexity to manage a new distributed system which must work in collaboration with each other to deliver the business functionalities. Reliability, fault tolerance, Tracing , Observability are some must-have aspect in a microservice architecture, add to it the functionality of canary deployment, traffic shifting and suddenly there is a whole layer of support system that is required for a service to deliver reliably.

The technology landscape for developers is changing rapidly. From monolith applications to microservices, from an application deployed on-premise datacenter to cloud platform, also applications deployed on virtualized machines to the containerized environment, the shift is huge. As a developer, it is important to keep up to date with this changing landscape both upgrading oneself as well as looking for a new job. As there are a plethora of technologies and there are always much hype and evangelism around a new technology it is always good to start with a much stable language, framework, and tool.
