End-to-End Tracing on Apache Dubbo

End-to-End Tracing Usage and Implementation Instructions

Mon, 01 Jan 0001 00:00:00 +0000

Dubbo has built-in end-to-end tracing capabilities. You can enable link tracing by introducing spring-boot-starter or related dependencies. By exporting trace data to mainstream implementations such as Zipkin, Skywalking, Jaeger, etc., you can achieve analysis and visualization of end-to-end tracing data.

Currently, Dubbo completes all tracing embedding through Micrometer Observation, relying on various Bridge adaptations provided by Micrometer, allowing us to import tracing into various back-end systems. The specific working principle is as follows.

OTlp

Overview

This example demonstrates how to use OpenTelemetry as a Tracer in a Dubbo project to report Trace information to the Otlp Collector, which then forwards it to Zipkin and Jagger. Code repository

It consists of three parts:

dubbo-samples-spring-boot-tracing-otel-oltp-interface
dubbo-samples-spring-boot-tracing-otel-oltp-provider
dubbo-samples-spring-boot-tracing-otel-oltp-consumer

Case Architecture Diagram

Quick Start

Install & Start Otlp Collector

Follow the OpenTelemetry Collector Quick Start to start the otlp collector.

Start Provider

Run org.apache.dubbo.springboot.demo.provider.ProviderApplication directly from the IDE.

Zipkin

This example demonstrates a basic example of Dubbo integrating Zipkin for end-to-end tracing. For the complete code, please refer to dubbo-samples-tracing-zipkin, which consists of three parts:

dubbo-samples-spring-boot3-tracing-provider
dubbo-samples-spring-boot3-tracing-consumer
dubbo-samples-spring-boot3-tracing-interface

Quick Start

Install & Launch Zipkin

Refer to Zipkin’s quick start to install Zipkin.

Here we use Docker to demonstrate how to quickly start the Zipkin service.

docker run -d -p 9411:9411 --name zipkin openzipkin/zipkin

Next, you can confirm that Zipkin is working properly through the following link: [http://localhost:9411](http://localhost:9411)

Skywalking

This article demonstrates how to integrate Dubbo with the Skywalking full-link monitoring system. For complete examples, please refer to dubbo-samples-tracing-skywalking. The required Skywalking Agent version is skywalking micrometer-1.10 api.

1. Add Micrometer Observation dependency to your project

To add Micrometer and related Metrics dependencies to the classpath, you need to include the dubbo-metrics-api dependency as follows:


<dependency>
 <groupId>org.apache.dubbo</groupId>
 <artifactId>dubbo-metrics-api</artifactId>
</dependency>

2. Add Skywalking Micrometer-1.10 Api to the project

To integrate Dubbo Micrometer tracing data into Skywalking, add the following dependency.
