我需要配置记录器以将消息写入具有不同日志级别的多个附加程序。

例如。我想RefreshDataService将详细信息记录TransportFileAppender到RollingFileAppender.

此外，我正在使用缓冲来提高日志记录性能。我设置FilteredFileLogappender 将警告转发到 FileLog->RollingFileAppender。

但是对于 RefreshDataService 记录器，包括调试和信息在内的所有日志消息都会记录到 FileLog 中。

您能帮我将记录器配置为RefreshDataService仅将 Warn+ 消息记录到 FileLog 吗？谢谢。

以下是我的 log4net 配置的摘录。

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="${TEMP}\logs\client\${ENV}\client.log" />
  <appendToFile value="true" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="4096KB" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level [%property{ENV}] [%property{UID}] %logger - %message%newline" />
  </layout>
</appender>

<appender name="TransportAppender" type="log4net.Appender.RollingFileAppender">
  <file value="${TEMP}\logs\client\${ENV}\client.comm.log" />
  <appendToFile value="true" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="4096KB" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
  </layout>
</appender>


<appender name="DetailedTransportLog" type="log4net.Appender.BufferingForwardingAppender">
  <threshold value="DEBUG" />
  <bufferSize value="200" />
  <appender-ref ref="TransportAppender" />
</appender>

<appender name="FileLog" type="log4net.Appender.BufferingForwardingAppender">
  <bufferSize value="20" />
  <lossy value="false" />
  <appender-ref ref="RollingFileAppender" />
</appender>

<appender name="FilteredFileLog" type="log4net.Appender.ForwardingAppender">
  <threshold value="WARN" />
  <appender-ref ref="FileLog" />
</appender>

<logger name="RefreshDataService" >
  <level value="DEBUG" />
  <appender-ref ref="FilteredFileLog" />
  <appender-ref ref="DetailedTransportLog" />
</logger>

您可以在 appender 上使用级别范围过滤器：

<filter type="log4net.Filter.LevelRangeFilter">
    <levelMin value="WARN" />
    <levelMax value="FATAL" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />

My understanding is that the Threshold property is used tell the appender to flush the buffer when messages of a certain level are logged. This way you can make for instance sure that errors are written immediately to the database.
