OpenTelemetry配置类 #

@Configuration
public class OtelConfiguration {
    @Bean
    OtlpHttpSpanExporter otlpHttpSpanExporter() {
        return OtlpHttpSpanExporter.builder()
                .setEndpoint("http://localhost:4318/v1/traces")
                .build();
    }
}

问题现象 #

• 直接启动应用时，Jaeger中仅能看到REST API的追踪数据，Mongo、Postgres、Redis的数据库请求追踪无法显示
• 使用OpenTelemetry Java Agent启动时，所有类型的追踪（包括数据库操作）均能正常在Jaeger中展示

Agent启动命令 #

java -javaagent:"/opt/eltropy/opentelemetry-javaagent.jar" -Dotel.service.name=rakesh-test  -jar /Users/rakesh/.m2/repository/com/radiant/eltropy/test-app/1.0.0/test-app-1.0.0.jar
