如何在Java中抑制开放遥测记录器

Question

我在Spring应用程序中使用Open遥测，对于每一个请求，Open遥测代理都会记录额外的日志行，我想要取消这些日志行。在客户端试图不断轮询kafka服务器状态时，日志太多了。io.opentelemetry.exporter.logging: ERROR似乎没有任何效果。

[opentelemetry.auto.trace 2021-03-30 09:20:12:470 -0700] [http-nio-9090-exec-1] INFO io.opentelemetry.exporter.logging.LoggingSpanExporter - 'PSFPublishAPIController.publish' : 785a452cf9bc6f901374af3c24491fc3 c3b50425ffd5090f INTERNAL [tracer: io.opentelemetry.javaagent.spring-webmvc-3.1:1.0.1] AttributesMap{data={thread.name=http-nio-9090-exec-1, thread.id=44}, capacity=128, totalAddedValues=2}

日志记录配置( yml: )

logging:
  level:
    root: ERROR
    com.org: DEBUG
    org.springframework: INFO
    io.opentelemetry.exporter.logging: ERROR
  pattern:
    console: '%d{HH:mm:ss.SSS} [%t,%X{trace_id}-%X{span_id}-%X{trace_flags}] %highlight{%-5level} %c{2.} - %msg%n'

启动程序命令：

java -javaagent:/Users/rshar248/Documents/Softwares/opentelemetry-javaagent-all.jar \
-Dotel.resource.attributes=service.name=psf-service \
-Dotel.traces.exporter=logging -Dotel.metrics.exporter=none \
-Dspring.profiles.active=local app.jar

任何关于如何抑制遥测内部日志线路的建议都将对我们有很大的帮助。

Answer 1

根据OpenTelemetry文档

可以使用-Dotel.javaagent.enabled=false (或使用等效的环境变量OTEL_JAVAAGENT_ENABLED=false)禁用代理。

Answer 2

要更改OpenTelemetry JavaAgent的日志级别，可以在命令行中使用命令系统属性io.opentelemetry.javaagent.slf4j.simpleLogger.defaultLogLevel。

例如，要完全禁用JavaAgent日志记录，可以将以下赋值添加到应用程序启动命令中：

-Dio.opentelemetry.javaagent.slf4j.simpleLogger.defaultLogLevel=off
