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，其中填充了我认为是实际 log4net 设置的日志记录。

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

并包含重复到几个 mb 文件的此类信息：

web.config 的相关部分如下所示：

  <log4net>
    <root>
      <level value="DEBUG" />
      <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>

日志配置如下：

XmlConfigurator.Configure();

并用作：

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

通过定期致电警告等。

我们尝试更改 LogFileAppender 的设置以在不同的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。日志记录按预期工作到正确的文件，问题是上述生成的文件大约是 1 GB/天，这很快就会填满我们的服务器。=/

我们如何停止 log4net 生成这些文件？（或减少到只生成一个有大小限制的）

如果您有任何问题或需要更多信息，请回复。

看起来您已启用 log4net 的内部调试。

您可以通过添加一个appSettings元素从 web.config 执行此操作：

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

或从代码：

log4net.Util.LogLog.InternalDebugging = true;

如果这发生在你程序的任何地方，log4net 将开始记录它所采取的每一个动作。
