如何过滤在log4net的自定义级别？ [英] How do I Filter on a custom Level in log4net?

问题描述

我复制了log4net的样本，以实现自定义日志级别，审计。我定义的审计有35000的值，DEBUG 30000和40000信息之间。

以下是我的配置部分。我有一个附加器记录所有级别和一个应该只记录审计级别（这只是用于测试）

 ＆LT; log4net的＆GT;
  ＆LT;附加目的地名称=FileAppenderTYPE =log4net.Appender.FileAppender＆GT;
    ＆LT;文件值=testrun.log/＆GT;
    ＆LT;布局类型=log4net.Layout.PatternLayout＆GT;
      ＆LT; conversionPattern值=％DATE {HH：MM：SS：FFF} [％线程]％-5level％记录器{1}  - ％消息％换行/＆GT;
    ＆LT; /布局＆GT;
  ＆LT; /附加器＆GT;
  ＆LT;附加目的地名称=FileAppender.AuditTYPE =log4net.Appender.FileAppender＆GT;
    ＆LT;滤波器类型=log4net.Filter.LevelMatchFilter＆GT;
      ＆LT; levelToMatch值=审计/＆GT;
    ＆LT; /滤光器＆gt;
    ＆LT;文件值=testrun.audit.log/＆GT;
    ＆LT;布局类型=log4net.Layout.PatternLayout＆GT;
      ＆LT; conversionPattern值=％DATE {HH：MM：SS：FFF} [％线程]％-5level％记录器{1}  - ％消息％换行/＆GT;
    ＆LT; /布局＆GT;
  ＆LT; /附加器＆GT;
  ＆LT;根＆GT;
    ＆LT;电平值=ALL/＆GT;
    ＆LT;附加目的地-REF REF =FileAppender/＆GT;
    ＆LT;附加目的地-REF REF =FileAppender.Audit/＆GT;
  ＆LT; /根＆GT;
＆LT; / log4net的＆GT;
 

测试方法

 私有静态只读IAuditLog登录= AuditLogManager.GetLogger（typeof运算（计划））;
公共静态无效的主要（）
{
    log.Debug（调试）;
    log.Audit（审计）;
    log.Info（信息）;
}
 

然而，附加目的地的输出是相同的...

  13：09：11：540 [9]调试程序 - 调试
13：09：11：560 [9]审计计划 - 审计
13：09：11：560 [9]广播节目 - 信息
 

解析LevelMatchFilter时，log4net的调试输出

  log4net的：加载追加程序[FileAppender.Audit]类型：[log4net.Appender.FileAppender]
log4net的：错误XmlHierarchyConfigurator：未知级别指定的[审计]
log4net的：WARN无法设置属性[levelToMatch]对象[log4net.Filter.LevelMatchFilter]利用价值[审计]（可接受的转换类型）
log4net的：设置集合属性[AddFilter]反对[log4net.Filter.LevelMatchFilter]
 

解决方案

log4net的1.2.10版本，您需要结束<$​​ C $ C> LevelMatchFilter 链带 DenyAllFilter 如果你想我的问题描述的行为。

 ＆LT;附加目的地名称=FileAppender.AuditTYPE =log4net.Appender.FileAppender＆GT;
  ＆LT;滤波器类型=log4net.Filter.LevelMatchFilter＆GT;
    ＆LT; levelToMatch值=审计/＆GT;
  ＆LT; /滤光器＆gt;
  ＆LT;滤波器类型=log4net.Filter.DenyAllFilter/＆GT;
  ＆LT;文件值=testrun.audit.log/＆GT;
  ＆LT;布局类型=log4net.Layout.PatternLayout＆GT;
    ＆LT; conversionPattern值=％DATE {HH：MM：SS：FFF} [％线程]％-5level％记录器{1}  - ％消息％换行/＆GT;
  ＆LT; /布局＆GT;
＆LT; /附加器＆GT;
 

I copied the log4net samples to implement a custom log level, AUDIT. I defined AUDIT to have a value of 35000, between DEBUG 30000 and INFO 40000.

The following is my configuration section. I have one appender that logs all levels and one that is supposed to log only AUDIT levels (this is just for testing)

<log4net>
  <appender name="FileAppender" type="log4net.Appender.FileAppender" >
    <file value="testrun.log" />
    <layout type="log4net.Layout.PatternLayout" >
      <conversionPattern value="%date{HH:mm:ss:fff} [%thread] %-5level %logger{1} - %message%newline" />
    </layout>
  </appender>
  <appender name="FileAppender.Audit" type="log4net.Appender.FileAppender" >
    <filter type="log4net.Filter.LevelMatchFilter">
      <levelToMatch value="AUDIT" />
    </filter>
    <file value="testrun.audit.log" />
    <layout type="log4net.Layout.PatternLayout" >
      <conversionPattern value="%date{HH:mm:ss:fff} [%thread] %-5level %logger{1} - %message%newline" />
    </layout>
  </appender>  
  <root>
    <level value="ALL" />
    <appender-ref ref="FileAppender" />
    <appender-ref ref="FileAppender.Audit" />
  </root>
</log4net>

The test method is

private static readonly IAuditLog log = AuditLogManager.GetLogger(typeof(Program));
public static void Main()
{
    log.Debug("Debug");
    log.Audit("Audit");
    log.Info("Info");
}

However, the output of the appenders is the same...

13:09:11:540 [9] DEBUG Program - Debug
13:09:11:560 [9] AUDIT Program - Audit
13:09:11:560 [9] INFO  Program - Info

The log4net debug output when parsing the LevelMatchFilter is

log4net: Loading Appender [FileAppender.Audit] type: [log4net.Appender.FileAppender]
log4net:ERROR XmlHierarchyConfigurator: Unknown Level Specified [AUDIT]
log4net:WARN Unable to set property [levelToMatch] on object [log4net.Filter.LevelMatchFilter] using value [AUDIT] (with acceptable conversion types)
log4net: Setting Collection Property [AddFilter] to object [log4net.Filter.LevelMatchFilter]

解决方案

log4net version 1.2.10 requires that you end a LevelMatchFilter chain with a DenyAllFilter if you want the behavior I described in the question.

<appender name="FileAppender.Audit" type="log4net.Appender.FileAppender" >
  <filter type="log4net.Filter.LevelMatchFilter">
    <levelToMatch value="AUDIT" />
  </filter>
  <filter type="log4net.Filter.DenyAllFilter" />
  <file value="testrun.audit.log" />
  <layout type="log4net.Layout.PatternLayout" >
    <conversionPattern value="%date{HH:mm:ss:fff} [%thread] %-5level %logger{1} - %message%newline" />
  </layout>
</appender>
