Feign Rest Client https://cloud.spring.io/spring-cloud-sleuth/reference/html/#feign
By default, Spring Cloud Sleuth provides integration with Feign through TraceFeignClientAutoConfiguration. You can disable it entirely by setting spring.sleuth.feign.enabled to false. If you do so, no Feign-related instrumentation take place.
Part of Feign instrumentation is done through a FeignBeanPostProcessor. You can disable it by setting spring.sleuth.feign.processor.enabled to false. If you set it to false, Spring Cloud Sleuth does not instrument any of your custom Feign components. However, all the default instrumentation is still there.
Distributed tracing support in NewRelic
Getting Started With New Relic Distributed Tracing NR supports auto instrument, which looks pretty cool. And not sure how well it works with the infinite tracing feature. If it could provides tracing for all requests, it would be awesome. And there are no needs to setup spring sleuth or zipkin if NR is used. NR supports both infinite tracing and head based tracing.
