Question

我们有几个使用log4net的ASP.NET MVC实例。实例很少将信息记录到指定的日志文件中。但是仍然会生成大量的log4net文件，这些文件充满了我假设记录的实际log4net设置。

生成的文件格式为[guid] log4net.txt。例： 6cec7387-2ca2-4186-b40d-35bf1f3fad39log4net.txt

并包含重复到几个mb文件的这类信息：

web.config的相关部分如下所示：

      <appender-ref ref="LogFileAppender" />
    </root>
    <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value=".\\App_Data\\Log[%processid]" />
      <param name="AppendToFile" value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
      </layout>
    </appender>
  </log4net>
  <system.diagnostics>
    <trace autoflush="true">
      <listeners>
        <add name="textWriterTraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="<logs path>\log4net.txt" />
      </listeners>
    </trace>
  </system.diagnostics>

日志配置为：

XmlConfigurator.Configure();

用作：

    protected static readonly log4net.ILog Log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

定期打电话给警告等。

我们尝试更改LogFileAppender的设置以在不同进程中使用不同的文件（如示例中所示）。并确保生成的文件中没有错误或冲突。日志记录按正常文件的方式工作，问题是上面描述的生成文件大约是1 GB /天，它可以非常快地填充我们的服务器。 = /

我们如何阻止log4net生成这些文件？（或将其减少为仅生成具有大小限制的一个）

您似乎已启用了log4net＆＃39; internal debugging。

您可以通过添加appSettings元素从web.config执行此操作：

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

或者来自代码：

log4net.Util.LogLog.InternalDebugging = true;

如果程序中的任何地方发生这种情况，log4net将开始记录它所执行的每个操作。

log4net使用重复文本创建和填充文件
