opentelemetry-spring-starter 介绍 -天翼云开发者社区

在当今的微服务架构和云原生环境中，可观测性成为了确保系统稳定性和性能的关键因素。为了应对这一挑战，OpenTelemetry项目应运而生，旨在为开发者提供一个标准化、与第三方无关的方式来收集、处理和导出遥测数据（包括指标、日志和追踪）。近日，OpenTelemetry社区宣布其Spring Starter已经达成稳定版，这标志着在Java应用中加入可观测性能力将变得更加简单和直接。

OpenTelemetry简介

OpenTelemetry是一个开源项目，由CNCF（云原生计算基金会）管理，它起源于OpenTracing和OpenCensus两个项目的合并。OpenTelemetry的目标是为云原生软件提供一套完整的可观测性解决方案，包括API、SDK以及各种插件和集成，以支持开发者轻松地将其应用与各种可观测性后端（如Zipkin、Jaeger、Prometheus等）进行集成。

Opentelemetry Spring Starter的意义

对于Java开发者来说，Spring框架无疑是最受欢迎的选择之一。因此，OpenTelemetry为Spring应用提供了一个专门的Starter，使得在Spring应用中加入可观测性能力变得轻而易举。这个Starter为Spring应用提供了自动配置和依赖管理，开发者只需要简单地添加几个依赖项，就可以开始收集和分析遥测数据了。

实战

从github拉取示例项目：

git clone github.com/spring-projects/spring-petclinic.git

在pom.xml中添加OpenTelemetry instrumentation BOM:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.opentelemetry.instrumentation</groupId>
            <artifactId>opentelemetry-instrumentation-bom</artifactId>
            <version>2.8.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

添加依赖项

<dependency>
  <groupId>io.opentelemetry.instrumentation</groupId>
  <artifactId>opentelemetry-spring-boot-starter</artifactId>
</dependency>

接下来可以编译sprint-boot-native-image应用（需要在PostgresIntegrationTests上加上@Disable，才能编译成功）：

cd spring-petclinic
mvn -Pnative spring-boot:build-image -Dspring-boot.build-image.imageName=spring-petclinic-native

starter使用OTLP协议发送数据，默认情况下使用http协议，也可以更换成gRPC协议。

接下来需要添加配置，让Opentelemetry-collector把监控数据打印出来（在spring-petclinic文件夹下添加docker-compose-otel.yml）：

version: '3.8'
services:
  app:
    image: spring-petclinic-native
    environment:
      OTEL_SERVICE_NAME: 'graal-native-example-app'
      OTEL_EXPORTER_OTLP_ENDPOINT: 'collector:4318'
    ports:
      - '8080:8080'
    depends_on:
      - collector
  collector:
    image: otel/opentelemetry-collector-contrib:0.109.0
    volumes:
      - ./collector-spring-native-config.yaml:/collector-spring-native-config.yaml
    command: ['--config=/collector-spring-native-config.yaml']
    expose:
      - '4317'
    ports:
      - '4317:4317'

添加collector-spring-native-config.yaml 配置文件

receivers:
  otlp:
    protocols:
      http:
        endpoint: '0.0.0.0:4318'
exporters:
  debug:
    verbosity: detailed
service:
  pipelines:
    metrics:
      receivers: [otlp]
      exporters: [debug]
    traces:
      receivers: [otlp]
      exporters: [debug]
    logs:
      receivers: [otlp]
      exporters: [debug]

运行程序：

docker-compose -f docker-compose-otel.yml up

从Opentelemetry-collector的日志中能看到类似这样的日志：

2024-09-16 14:19:11 collector-1  | LogRecord #2

2024-09-16 14:19:11 collector-1  | Body: Str(Started PetClinicApplication in 0.489 seconds (process running for 0.493))

它表明OpenTelemetry Spring Boot starter 已经接入了LogBack并且把“Started PetClinicApplication in 0.489 seconds (process running for 0.493)” 这条日志发送到了collector。

接下来可以访问

curl localhost:8080/vets.html

从collector能看到如下日志，它表明目标程序对这次http请求生成了一个span，它的traceId是16a0a5be5127309858c7c63a76b3f471 （你的代码中可能是其他traceId）：

上面的例子展示了如何集成Opentelemetry spring boot starter，并展示starter对指标、日志、链路数据的采集能力。你可以开始收集和分析你的应用的遥测数据，从而优化应用并提高性能。

请注意，具体的配置和代码可能需要根据你的具体需求和OpenTelemetry的版本进行调整。建议查阅OpenTelemetry的官方文档和示例，以获取更多详细的信息和示例。
