여러 파일에 쓰도록 Log4net 구성

여러 파일에 쓰도록 Log4net 구성

---

동일한 프로세스에서 2 개의 다른 로그 파일에 로그를 작성하고 싶습니다.

log4net을 사용하여 가능한 일입니까?

각 로그 파일에 별도의 메시지를 작성해야합니다. 특정 추가 자에게 메시지를 작성하려면 어떻게해야합니까?

예, 로거에 여러 FileAppender를 추가하십시오. 예를 들면 다음과 같습니다.

<log4net>
    <appender name="File1Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-1.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>
    <appender name="File2Appender" type="log4net.Appender.FileAppender">
        <file value="log-file-2.txt" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %message%newline" />
        </layout>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="File1Appender" />
        <appender-ref ref="File2Appender" />
    </root>
</log4net>

이 답변은 도움이되었지만 app.config 부분과 c # 코드 부분 모두와 답변을 공유하고 싶었으므로 다음 사람에 대한 추측이 적습니다.

<log4net>
  <appender name="SomeName" type="log4net.Appender.RollingFileAppender">
    <file value="c:/Console.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
  </appender>
  <appender name="Summary" type="log4net.Appender.FileAppender">
    <file value="SummaryFile.log" />
    <appendToFile value="true" />
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="SomeName" />
  </root>
  <logger additivity="false" name="Summary">
    <level value="DEBUG"/>
    <appender-ref ref="Summary" />
  </logger>
</log4net>

그런 다음 코드에서 :

ILog Log = LogManager.GetLogger("SomeName");
ILog SummaryLog = LogManager.GetLogger("Summary");
Log.DebugFormat("Processing");
SummaryLog.DebugFormat("Processing2"));

여기서 c : /Console.txt에는 "Processing"이 포함되고 \ SummaryFile.log에는 "Processing2"가 포함됩니다.

비네이 맞습니다. 그의 답변에 대한 귀하의 의견에 대한 답변에서 귀하가 할 수있는 한 가지 방법은 다음과 같습니다.

<root>
    <level value="ALL" />
    <appender-ref ref="File1Appender" />
</root>
<logger name="SomeName">
    <level value="ALL" />
    <appender-ref ref="File1Appender2" />
</logger>

이것이 내가 과거에 한 일입니다. 그런 다음 다른 로그에 대해 다음과 같이하십시오.

private static readonly ILog otherLog = LogManager.GetLogger("SomeName");

그리고 당신은 다음과 같이 일반 로거를 얻을 수 있습니다 :

private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

Read the loggers and appenders section of the documentation to understand how this works.

I wanted to log all messages to root logger, and to have a separate log with errors, here is how it can be done:

<log4net>
    <appender name="FileAppender" type="log4net.Appender.FileAppender">
        <file value="allMessages.log" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date  %-5level %logger  - %message%newline" />
        </layout>
    </appender>

    <appender name="ErrorsFileAppender" type="log4net.Appender.FileAppender">
        <file value="errorsLog.log" />
        <appendToFile value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date  %-5level %logger  - %message%newline" />
        </layout>
        <filter type="log4net.Filter.LevelRangeFilter">
            <levelMin value="ERROR" />
            <levelMax value="FATAL" />
        </filter>
    </appender>

    <root>
        <level value="ALL" />
        <appender-ref ref="FileAppender" />
        <appender-ref ref="ErrorsFileAppender" />
    </root>
</log4net>

Notice the use of filter element.

Use below XML configuration to configure logs into two or more files,

<log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="logs\log.txt" />         
      <appendToFile value="true" /> 
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">           
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
    </appender>
     <appender name="RollingLogFileAppender2" type="log4net.Appender.RollingFileAppender">
      <file value="logs\log1.txt" />         
      <appendToFile value="true" /> 
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">        
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="All" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
     <logger additivity="false" name="RollingLogFileAppender2">
    <level value="All"/>
    <appender-ref ref="RollingLogFileAppender2" />
    </logger>
  </log4net>

Above XML configuration logs into two different files.

To get specific instance of logger programmatically ,

ILog logger = log4net.LogManager.GetLogger ("RollingLogFileAppender2");

You can append two or more appender elements inside log4net root element for logging into multiples files.

More info about above XML configuration structure or which appender is best for your application , Read detail from below link,

Hope this will help.
