log4net的不写入文件 [英] Log4net doesn't write to file

问题描述

我要添加新日志文件。这个是我的appender：

<预类=郎咸平的XML prettyprint-覆盖> <附加器NAME =RollingFileAppender进行TYPE =log4net.Appender.RollingFileAppender>
<文件值=mylogfile.txt/>
< appendToFile值=真/>
< rollingStyle值=大小/>
< maxSizeRollBackups值=5/>
< maximumFileSize值=10MB/>
< staticLogFileName值=真/>
<滤波器类型=log4net.Filter.StringMatchFilter>
< stringToMatch值=测试/>
< /滤光器>
<滤波器类型=log4net.Filter.StringMatchFilter>
< stringToMatch值=错误/>
< /滤光器>
<滤波器类型=log4net.Filter.DenyAllFilter/>
<布局类型=log4net.Layout.PatternLayout>
< conversionPattern值=％DATE [％线程]％的水平记录仪％ - ％讯息％换行符％的异常/>
< /布局>
< /附加器>
<根和GT;
<电平值=全部/>
<附加目的地-REF REF =RollingFileAppender进行/>
< /根>


和上我的课我想补充

  [汇编：XmlConfigurator（手表= TRUE）] 
  

和我添加访问大家的文件，但：log4net的不写入文件。为什么呢？

解决方案

log4net的失败默默时，有一个问题。设计自负是没有记录最好采取关闭应用程序。要弄清楚什么是错的，打开log4net的内部调试中加入这关键是你的[应用程序/网络] config文件：

  <&的appSettings GT; 
<添加键=log4net.Internal.DebugVALUE =真/> 
< /的appSettings> 
  

调试消息将被写入到控制台或 System.Diagnostics程序.Trace 系统。从菲尔·哈克更多细节在 http://haacked.com/archive/2006/09/26/Log4Net_Troubleshooting的.aspx /

有任何原因log4net的可能会失败。在日志文件目录的权限问题，起动器（用于服务器进程，在自己可能的一组有限的安全权限下运行尤其如此）。

I want add new log to file.this is my appender:

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="mylogfile.txt"/>
  <appendToFile value="true"/>
  <rollingStyle value="Size"/>
  <maxSizeRollBackups value="5"/>
  <maximumFileSize value="10MB"/>
  <staticLogFileName value="true"/>
  <filter type="log4net.Filter.StringMatchFilter">
    <stringToMatch value="test"/>
  </filter>
  <filter type="log4net.Filter.StringMatchFilter">
    <stringToMatch value="error"/>
  </filter>
  <filter type="log4net.Filter.DenyAllFilter"/>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
  </layout>
</appender>
<root>
  <level value="All"/>
  <appender-ref ref="RollingFileAppender"/>
</root>

and on my class I add

[assembly: XmlConfigurator(Watch = true)]

and I add access everyone for the file but: log4net doesn't write to file. Why?

解决方案

Log4net fails silently when there's a problem. The design conceit is that no logging is preferable to taking down the application. To figure out what's wrong, turn on Log4net's internal debugging by adding this key to your [app/web].config file:

<appSettings>
  <add key="log4net.Internal.Debug" value="true"/>
</appSettings>

The debug messages will be written to the console or to the System.Diagnostics.Trace system. More details from Phill Haack at http://haacked.com/archive/2006/09/26/Log4Net_Troubleshooting.aspx/

There are any number of reasons Log4net might fail. Permissions problems on the log file directory, for starters (especially true for server processes, where your likely running under a restricted set of permissions for security).
