如何在log4net中将不同的日志级别记录到不同的日志附加程序 [英] How to log different log level to different log appender in log4net

问题描述

我有一个WinForm，它显示日志信息，但我希望它仅显示为INFO级别，但是我希望日志文件中的日志也包含DEBUG级别.

I have a WinForm that it display log information but I want it to display to only INFO level but I want the log in the log file to contain DEBUG level as well.

下面是我的配置:

<?xml version="1.0" encoding="utf-8" ?>
<!-- This section contains the log4net configuration settings -->
<log4net>
  <!-- Define some output appenders -->

  <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="${ALLUSERSPROFILE}\\Application Data\\logs\\Gateway" />
    <appendToFile value="true" />
    <rollingStyle value="Date" />
    <param name="StaticLogFileName" value="false" />
    <datePattern value=".yyyyMMdd.lo\g" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date | [%thread] | %-5level | %logger | %message %newline" />
    </layout>
  </appender>

  <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
    </layout>
  </appender>

  <appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
    <mapping>
      <level value="DEBUG" />
      <backColor value="Blue" />
    </mapping>
    <mapping>
      <level value="INFO" />
      <backColor value="Green" />
    </mapping>
    <mapping>
      <level value="WARN" />
      <backColor value="Yellow" />
    </mapping>
    <mapping>
      <level value="ERROR" />
      <backColor value="Red" />
    </mapping>
    <mapping>
      <level value="FATAL" />
      <backColor value="Red, HighIntensity" />
    </mapping>
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
    </layout>
  </appender>

  <appender name="RichTextBoxAppender" type="Gateway.RichTextBoxAppender,Gateway" >
    <layout type="log4net.Layout.PatternLayout">
      <param name="Header" value="[Header]\r\n"/>
      <param name="Footer" value="[Footer]\r\n"/>
      <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n" />
    </layout>
    <mapping>
      <level value="DEBUG" />
      <textColorName value="DarkGreen" />
    </mapping>
    <mapping>
      <level value="INFO" />
      <textColorName value="ControlText" />
    </mapping>
    <mapping>
      <level value="WARN" />
      <textColorName value="Blue" />
    </mapping>
    <mapping>
      <level value="ERROR" />
      <textColorName value="Red" />
      <bold value="true" />
      <pointSize value="10" />
    </mapping>
    <mapping>
      <level value="FATAL" />
      <textColorName value="Black" />
      <backColorName value="Red" />
      <bold value="true" />
      <pointSize value="12" />
      <fontFamilyName value="Lucida Console" />
    </mapping>
  </appender>


  <!-- Setup the root category, add the appenders and set the default level -->
  <root>
    <level value="WARN" />
    <appender-ref ref="LogFileAppender" />
    <appender-ref ref="ColoredConsoleAppender" />
    <appender-ref ref="RichTextBoxAppender" />
  </root>

  <logger name ="Gateway" additivity="false">
    <level value="INFO" />
    <appender-ref ref="LogFileAppender" />
    <appender-ref ref="ColoredConsoleAppender" />
    <appender-ref ref="RichTextBoxAppender" />
  </logger>



</log4net>

现在，LogFileAppender和RichTextBoxAppender均设置为INFO.我尝试在Gateway记录器中取出LogFileAppender并移到另一个记录器，并为此新记录器设置为"DEBUG"级别，但是它仍然在做另一个.如何配置它，以使LogFileAppender具有DEBUG级别，RichTextBoxAppender具有INFO级别?

Right now it is set to INFO for both LogFileAppender and RichTextBoxAppender. I tried taking out the LogFileAppender in Gateway logger and move to another logger and set to "DEBUG" level for this new logger but it is still doing one or the other. How do I configure it so that the LogFileAppender has DEBUG level and RichTextBoxAppender has INFO level?

推荐答案

您应该能够将过滤器添加到两个追加器中.

You should be able to add a filter to both of your appenders.

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

通过这种方式，一个追加器将仅记录到某个级别，而另一个追加器将记录到另一个级别，即使它们是由同一记录器定义的.

This way one appender will only log to a certain level while the other to a different level even though they are defined by the same logger.
