用OpenTelemetry

Question

使用Spring Boot 3.4.2，我想使用弹簧执行器配置以OpentElemetry格式配置日志导出。示例属性：

management.otlp.logging.export.enabled=true
management.otlp.logging.endpoint=http://localhost:4318/v1/logs
management.otlp.logging.headers.apikey=apikey
management.otlp.logging.transport=http
management.otlp.logging.compression=gzip

tried添加Maven依赖性：

<dependency>    
    <groupId>io.opentelemetry.instrumentation</groupId>   
    <artifactId>opentelemetry-spring-boot-starter</artifactId>
    <version>2.12.0</version>
</dependency>

<dependency>    
    <groupId>io.opentelemetry</groupId>    
    <artifactId>opentelemetry-exporter-otlp</artifactId> 
    <version>${opentelemetry.version}</version>
</dependency>

<dependency>    
    <groupId>io.opentelemetry.instrumentation</groupId>   
    <artifactId>opentelemetry-logback-appender-1.0</artifactId>    
    <version>1.28.0-alpha</version>
</dependency>

logback.xml示例：

<configuration scan="true" scanPeriod="30 seconds">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{"yyyy-MM-dd'T'HH:mm:ss.SSSXXX", UTC} [%thread] %-5level %logger{36} - %msg %replace(%replace(%ex){'[\r\n]+', ''}){'[\t]+', '&#10;&#9;'}%nopex%n</pattern>
        </encoder>
    </appender>

    <appender name="otel" class="io.opentelemetry.instrumentation.logback.appender.v1_0.OpenTelemetryAppender">
        <captureExperimentalAttributes>true</captureExperimentalAttributes>
        <captureKeyValuePairAttributes>true</captureKeyValuePairAttributes>
    </appender>

    <root level="INFO">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="otel" />
    </root>
</configuration>

但指出工作或配置未设置为otlphttplogrecordexporter。还有什么需要配置或我做错了什么？

Answer 1

io.opentelemetry.instrumentation:opentelemetry-spring-boot-starter:2.12.0

在application.yml

中使用这些设置

otel:
  exporter:
    otlp:
      endpoint: http://localhost:8080
      headers:
        apikey: apikey
  traces:
    exporter: none
  metrics:
    exporter: none

management:
  otlp:
    logging:
      export:
        enabled: true

和此控制器模拟端点

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.bind.annotation.RequestBody;

@RestController
@RequestMapping("/v1")
public class OtlpEmulationController {

    private static final Logger logger = LoggerFactory.getLogger(OtlpEmulationController.class);

    @PostMapping("/logs")
    public ResponseEntity<Void> receiveLogs(
            @RequestBody String logData,
            @RequestHeader String apikey) {

        // logger.info("Received log data: {}", logData);

        // Respond with success
        return ResponseEntity.noContent().build();
    }

    // optional, will only be invoked when removing traces.exporter=none
    @PostMapping("/traces")
    public ResponseEntity<String> receiveTraces(@RequestBody String tracesPayload) {
        return ResponseEntity.ok("Successfully received traces");
    }
}

我们可以通过请求例如/actuator/health/lices.
