Getting Observability Right with Spring AI and WebFlux https://luizvieira.me/spring-ai-webflux-observability/ Sat, 01 Nov 2025 12:30:24 -0900 https://luizvieira.me/spring-ai-webflux-observability/ How I got observability working in my reactive Spring AI app using WebFlux, after hours debugging tracing and context propagation issues. Fixing Tracing Propagation in Spring WebFlux in One Line https://luizvieira.me/micrometer-tracing-spring-webflux-propagation/ Mon, 27 Jan 2025 17:15:24 -0800 https://luizvieira.me/micrometer-tracing-spring-webflux-propagation/ Upgrading to Spring Boot 3.2 revealed tracing issues in a WebFlux service. A single line of code fixed broken span propagation and improved debugging. Spring Boot 3 Upgrade Lost 90% of Our Distributed Traces https://luizvieira.me/spring-boot-3-tracing-sampling-default-probability/ Wed, 17 Jul 2024 08:44:24 -0700 https://luizvieira.me/spring-boot-3-tracing-sampling-default-probability/ After upgrading Spring Boot version to 3.3.1 we noticed that 90% of our distributed tracing in our observability tool were gone. In this post we tell the story Spring Sleuth to Micrometer Migration in Spring Boot 3 https://luizvieira.me/spring-boot-3-spring-sleuth-micrometer-migration/ Thu, 11 Apr 2024 20:55:24 -0700 https://luizvieira.me/spring-boot-3-spring-sleuth-micrometer-migration/ Spring Sleuth was removed in Spring Boot version 3 in favor of Micrometer and I recently migrated many services and want to share the learnings with you.
