By adding Spring Cloud Sleuth as a dependency in my Spring Boot project the logging mask, like magic, changes.
The change that happens is the inclusion of the traceId, spanId and applicationName in the informations that are logged when I do log.info(...) and other logging commands.
How do Spring Cloud Sleuth does that? Is that a appender implementation? Do a programatically change happens in the log mask to be able to print it when Spring Boot auto-configuration is started?

I have upgraded my project to spring boot 2.6.11 and spring cloud 2021.0.4. After that, the parentId disappeared from the log.
I am using logback to logging purpose. So there is a way to display it?
I added a logging pattern but it didn't change anything:
logging.pattern.level=%5p [${spring.application.name:-},%X{X-B3-TraceId:-},%X{X-B3-SpanId:-},%X{X-Span-Export:-}]
Can Spring Cloud Data Flow be used in Spring5 applications - NOT Spring Boot - my current employer seems to view Spring Boot applications as insecure (I've no idea why) in anyway I'd like to try use this stack for an integration project, so is it possible to use it without Spring Boot?
With Spring Cloud Data Flow you can deploy streams, tasks and batches.
This is all based on Spring, Spring Cloud and Spring Boot. Spring Boot is nothing else as a preconfigured Spring stack.
Spring Data Flow is a runitme that usually needs a cloud infrastructure like Kubernets.
I'm not sure if you really are looking for that or more for something like https://spring.io/projects/spring-integration
I would like to ask how to refresh spring boot configuration info with using spring cloud config. Would you please give me some advice? Many thanks.
If your spring boot application is a client of Spring Cloud Configuration Server and use itself as single point of truth in the application configuration let's say retrieve application.properties/yml from the config server, you can benefit of #RefreshScope. in this case if you do a post to the /refresh if you use spring boot 1.x or /actuator/refresh if you use spring boot 2.x all the bean that are have are annotated as #RefreshScope will be refreshed.
We are trying to implement Spring cloud sleuth with Zipkin in our project and wanted to know if Spring cloud sleuth will support DB calls with Spring data JPA.
I want to trace the time taken for DB calls just like service calls
When I make a service call with RestTemplate, that gets sent to zipkin and I am able to see that on the dashboard
But DB interactions with Spring data jpa is not getting displayed in Zipkin
You can use the new Dalston feature of using annotations on Spring Data repositories. You can check out this for more info http://cloud.spring.io/spring-cloud-sleuth/spring-cloud-sleuth.html#_managing_spans_with_annotations
Can we use the Spring Boot Actuator in the traditional shared container within the context of an application? If so, how would be the configuration look like?
I have tried it by bootstrapping EndpointWebMvcAutoConfiguration. However, could not map mvc urls.
There's nothing stopping you from just using it as a dependency. Any Spring Boot app should be able to use actuator features out of the box.
