Logback 日志级别更改不起作用

Question

我正在使用一个名为 Apache Drill 的应用程序，它使用 logback 进行日志记录。我正在尝试编辑它附带的 logback.xml 配置文件以输出调试消息。

这是文件，未动过

  <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>

之后我所做的就是编辑

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

成为

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

绝对没有任何改变！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，但仍然没有任何改变。我在日志中找不到一个 DBEUG。

您所做的更改应该有效。我做了同样的更改和运行一个钻头，我可以在 drillbit.log 中看到调试日志。例如：

DEBUG o.a.drill.exec.server.StartupOptions - Parsing arguments.

drillbit.out 文件应该会告诉您一些有关 Logback 如何配置自身的信息。查看该文件，特别是与 LoggerContext 相关的条目，例如：

Found resource [logback.xml] at ...

Resource [logback.xml] occurs multiple times on the classpath

您可能会发现 Logback 通过它自己的日志记录来揭示答案。
