In this chapter, you learned how the trace/correlation ID is important and how it can be set up using Micrometer with Brave. You can use these generated IDs to find the relevant logs and API call durations. You integrated the Spring Boot services with the ELK stack and Zipkin.

You also implemented extra code and configurations, which are required for enabling distributed tracing for gRPC-based services.

You acquired log aggregation and distributed tracing skills using Micrometer, Brave, the ELK stack, and Zipkin.
