- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
## Describe the proposal
<!-- Please use this for a concrete design proposal for functionality. -->
<!-- If you just want to request a new feature and discuss the possible business value, create a Feature Request. -->
English: As a low-level framework middleware, Dubbo needs to reduce the coupling with the third-party link tracking system as much as possible, so a solution is needed to realize it. Currently, the more popular link tracking facades that can be referred to are: opentracing and micrometer tracing. Of course, there are other better options that you can also try.
中文：Dubbo作为一个底层的框架中间件，需要尽可能的降低与第三方链路追踪系统的耦合，所以需要一个解决方案来实现，目前可以参考的比较流行的链路追踪门面为：opentracing与micrometer tracing。当然还有其他更好的也可以尝试选择。

# Opentelemetry与Micrometer tracing选型调研
## 二者对比
| Opentelemetry | Micrometer
-- | -- | --
语言 | 异构，支持多种语言 | 只支持Java，spring-boot3默认集成
Trace | 标准统一API | micrometer-tracing-bridge-otel可转为OT
支持第三方 | Zipkin, Jaeger, skywalking, Prometheus等 | 通过brave机制可对接第三方
背景 | CNCF孵化项目之一 | 后起之秀
文档地址 | https://opentelemetry.io/docs/ | https://micrometer.io/docs
## 为什么SpringBoot选择Micrometer（[参考](https://juejin.cn/post/7173914390352101412)）？
SpringBoot 使用 Micrometer 而不是 OpenTelemetry，可能有以下几点原因：
1. 在之前的一些版本中，Micrometer关注更多是metrics，而OpenTelemetry则更多关注tracing，但是随着版本的迭代完善，Micrometer和OpenTelemetry在metrics和tracing API上基本都具备了。重要的是，在此之前，SpringBoot已经对Micrometer Metrics进行了支持，所谓近水楼台先得月。
2. OpenTelemetry的目标是厂商无关，语言无关，openTelemetry更适合在异构技术栈中发挥作用；而Micrometer一直以来都是基于Java语言，这与 Spring体系从根上是一致的。
3. Micrometer API 进行大量更改。最重要的变化是引入了一个新的 API：Observation API，这样便于使用者能够使用统一的 API 来观测业务代码，包括metrics，tracing以及logging。
SpringBoot3在Spring Boot Actuator中为Micrometer Tracing的依赖性管理和自动配置。Micrometer Tracing充当了类似日志领域内slf4j门面的角色。
OpenTelemetry目前实现了对Dubbo的client和server：
[https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/docs/supported-libraries.md](https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/docs/supported-libraries.md)
## 个人意见：Micrometer
- Springboot3默认自带依赖，用户无需单独引入
- Tracing这块的默认protocol可以选择Micrometer，可通过micrometer-tracing-bridge-otel转换otel。参考[https://micrometer.io/docs/tracing](https://micrometer.io/docs/tracing)。
