Question

我正在使用名为Apache Drill的应用程序，该应用程序使用logback进行日志记录。我正在尝试编辑 logback.xml 配置文件以输出调试消息。

这是文件，未触动

  <logger name="org.apache.drill" additivity="false">
    <level value="info" />
    <appender-ref ref="FILE" />
  </logger>

  <logger name="query.logger" additivity="false">
    <level value="info" />
    <appender-ref ref="QUERY" />
    <!--     <appender-ref ref="SOCKET" /> -->
  </logger>

  <!-- 
  <logger name="org.apache.drill" additivity="false">

  </logger>
   -->

  <root>
    <level value="error" />
    <appender-ref ref="STDOUT" />
  </root>

</configuration>

之后我所做的只是编辑

<logger name="org.apache.drill" additivity="false">
  <level value="info" />
  <appender-ref ref="FILE" />
</logger>

是

<logger name="org.apache.drill" additivity="false">
  <level value="debug" />
  <appender-ref ref="FILE" />
</logger>

绝对没有改变！这是用于启动应用程序的java命令（搜索-cp /home/gelbana/drillv11/conf，logback.xml文件位于 conf 目录中）

/usr/java/jdk1.8.0_112/bin/java -Xms10G -Xmx10G -XX:MaxDirectMemorySize=230G -XX:ReservedCodeCacheSize=1G -Ddrill.exec.enable-epoll=false -XX:MaxPermSize=512M -Djava.io.tmpdir=/home/gelbana/drillv11/tmp -Ddrill.memory.debug.allocator=true -XX:+CMSClassUnloadingEnabled -XX:+UseG1GC -Dlog.path=/home/gelbana/drillv11/log/drillbit.log -Dlog.query.path=/home/gelbana/drillv11/log/drillbit_queries.json -cp /home/gelbana/drillv11/conf:/home/gelbana/drillv11/jars/*:/home/gelbana/drillv11/jars/ext/*:/home/gelbana/drillv11/jars/3rdparty/*:/home/gelbana/drillv11/jars/classb/* org.apache.drill.exec.server.Drillbit

drillbit.out文件在开头有以下几行

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/3rdparty/slf4j-simple-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/classb/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]

我尝试将所有级别更改为 DEBUG ， ALL ，但仍然没有任何更改。我无法在日志中找到一个 DBEUG 。

Answer 1

您所做的更改应该有效。我做了同样的更改并运行了一个钻头，我可以在drillbit.log中看到调试日志。例如：

DEBUG o.a.drill.exec.server.StartupOptions - 解析参数。

drillbit.out文件应该告诉您Logback如何自行配置。查看该文件，特别是与LoggerContext相关的条目，例如：

在...
找到资源[logback.xml]
资源[logback.xml]在类路径上多次出现

你可能会发现Logback通过它自己的日志来重现答案。

Logback日志级别更改无效
