此配置应该使我的日志条目最终在自定义日志中,对吧？但它最终会出现在应用程序日志中.我的应用以管理员身份运行.运行我的应用程序后,我可以确认使用EventLog.Exists("MyLog")和创建了日志和事件源EventLog.SourceExists("MyApplication").

<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
  <logName value="MyLog"/>
  <applicationName value="MyApp" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger - %message %exception%newline" />
  </layout>
</appender>

编辑:我发现问题是什么,但直到8h过去,我才能"自我回答"我的问题.

我是第一次使用log4net,并使用提供的配置示例跟踪文档,但是调试语句不记录.

信息,错误,警告和致命级别都正确记录.谁能告诉我我失踪了什么？

的app.config:

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

<log4net>
    <appender name="Console" type="log4net.Appender.ColoredConsoleAppender">

        <mapping>
            <level value="INFO" />
            <foreColor value="Green"/>
        </mapping>

        <mapping>
            <level value="DEBUG" />
            <foreColor value="Cyan,HighIntensity"/>

        <layout type="log4net.Layout.PatternLayout">
            <!-- Pattern to output the caller's file name and line number -->
            <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
        </layout>            
    </appender>

    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
        <file value="example.log" />
        <appendToFile value="true" />
        <maximumFileSize …

我是第一次尝试配置log4net,我确定我已经正确配置了所有内容,但是,在获取空日志文件后,我打开了log4net调试器.我现在不断看到以下错误:

log4net:ERROR [RollingFileAppender] ErrorCode: GenericFailure. Unable to acquire lock on 
file "file path\file name" The process cannot access the file "file path\file name" because 
it is being used by another process.

我目前通过我的Web.config文件配置了log4net:

<log4net debug="true">
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="Logs\\TransferPicturesApplicationLog.txt"/>
  <appendToFile value="true"/>
  <rollingStyle value="Size"/>
  <maxSizeRollBackups value="5"/>
  <maximumFileSize value="10MB"/>
  <staticLogFileName value="true"/>
  <filter type="log4net.Filter.LevelRangeFilter">
    <param name="LevelMin" value="ERROR"/>
    <param name="LevelMax" value="DEBUG"/>
  </filter>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %level %logger - %message%newline"/>
  </layout>
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
</appender>
<root>
  <level value="INFO"/>
  <appender-ref ref="RollingFileAppender"/>
</root>
<logger>
  <level …

我正在使用ADONetAppender(尝试)通过存储过程记录数据(这样我可以将逻辑注入日志记录例程).

我的配置设置如下所示.谁能说出我做错了什么？

<appender name="ADONetAppender_SqlServer" type="log4net.Appender.ADONetAppender">
  <bufferSize value="1" />
  <threshold value="ALL"/>
  <param name="ConnectionType" value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

         </layout>
      </parameter>
      <parameter>
         <parameterName value="@LogLevel"/> …

我有一个Log4Net RollingFileAppender配置为:

<configuration>

  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>

  <log4net>

    <root>
      <level value="ALL" />
    </root>

    <logger name="RollingFileAppender" additivity="false">
      <level value="DEBUG"/>
      <appender-ref ref="RollingFileAppender" />
    </logger>

    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender" >
      <param name="File" value="C:\\MyLog.log" />
      <param name="AppendToFile" value="true" />
      <param name="DatePattern" value="yyyy-MM-dd"/>
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%m%n"/>
      </layout>
    </appender>

  </log4net>

</configuration>

查看文档,默认滚动样式是Composite,因此当它达到特定大小(默认值为10MB)时,它将会滚动,而不仅仅是在日期.

问题是当它达到大小时,它正在重新启动日志并且我从前半天丢失数据(它在中午左右达到这个大小).
为什么这不会只是滚动到一个新文件,所有未来的日志行都被放入MyLog.log？或者是日志正在滚动,但是在午夜,它再次滚动并覆盖过时的日志(例如,一旦达到10MB,滚动到MyLog.log2009-04-08,然后在午夜覆盖同一个文件)？

我会设置

<rollingStyle value="Date" />

这是我要做的就是确保它只在日期边界滚动吗？我可以在Log4Net.config中动态更改,还是必须重新启动应用程序？它在IIS6上运行.

我正在使用log4net和AdoNetAppender.它将所有日志信息记录到表中.该表实际上有2个整数列(可以为null).

这是我的log4net配置的相关部分:

<commandText value="INSERT INTO ActivityLog ([Date],[Thread],[Level],[Logger],[Message],[DealID]) 
                 VALUES (@log_date,@thread,@log_level,@logger,@message,@DealID)" />

 //other parameters hten DealID
<parameter>
      <parameterName value="@DealID" />
      <dbType value="Int32" />
       <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%property{DealID}" />
      </layout>
    </parameter>

我发现的是,如果我没有明确设置使用类似的东西log4net.ThreadContext.Properties["DealID"] = DealID;会引发异常:

System.FormatException occurred
  Message="Failed to convert parameter value from a String to a Int32."
  Source="System.Data"
  StackTrace:
       at System.Data.SqlClient.SqlParameter.CoerceValue(Object value, MetaType destinationType)
  InnerException: System.FormatException
       Message="Input string was not in a correct format."
       Source="mscorlib"
       StackTrace:

            at System.Number.ParseInt32(String s, NumberStyles …

我正在努力让Castle Windsor的log4net集成工作.我用类型的公共属性编写了我的类,ILogger并在我的app.config中进行了配置,如下所示.

<configuration>
  <configsections>
    <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configsections>

  <castle>
    <facilities>
      <facility id="logging" type="Castle.Facilities.Logging.LoggingFacility, Castle.Facilities.Logging" loggingApi="log4net" />
    </facilities>
    <components>
      <component id="form1" type="WinFormsActiveRecordSample.Form1, WinFormsActiveRecordSample" />
    </components>
  </castle>
  <log4net>
    <root>
      <level value="ALL" />
      <appender-ref ref="FileAppender" />
    </root>
    <appender name="FileAppender" type="log4net.Appender.FileAppender">
      <file value="main.log" />
      <appendToFile value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date{dd.MM.yy HH:mm:ss} %-5level %logger - %message%newline" />
      </layout>
    </appender>
  </log4net>
</configuration>

在我看来,这应该是有效的,但事实并非如此.当我loggingApi="console"正确设置日志时.当我将其更改为log4net时,它什么也没做.log4net配置来自块正在运行的另一个项目.我该怎么做才能使用日志文件？必须有特殊的log4net配置吗？

谢谢你的任何提示

我刚刚开始使用Log4Net ...我现在想要发送一封电子邮件,其中包含附加或直接邮寄的完整日志.使用SmtpAppender的问题在于它需要一个未知的bufferSize,因为它应该发送邮件,无论是充满错误还是信息.

更新:我的配置文件

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">

    <to value="ebb@mail.com" />
    <from value="ebb@mail.com" />
    <subject value="Backup Application - Log" />
    <smtpHost value="mailserver" />
    <authentication value="1" />
    <username value="userName" />
    <password value="mypw" />

    <port value ="25"/>
    <lossy value="true" />
    <bufferSize value="500" />

    <evaluator type="log4net.Core.LevelEvaluator">
        <threshold value="ALL"/>
    </evaluator>

    <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%timestamp [%thread] %-5level %logger – %message%newline" />
    </layout>

</appender>

我使用log4net来记录错误.

目前我下载了该文件log4net.dll,然后在global.asax文件中进行了以下更改:

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

protected void Application_Start(object sender, EventArgs e)
{
    log4net.Config.XmlConfigurator.Configure();
}
protected void Application_Error(object sender, EventArgs e)
{
    Log.Fatal("An uncaught exception occurred", this.Server.GetLastError());
}

这些更改也是在web.config文件中进行的

<log4net>

<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
  <param name="File" value="c:\Log4NetExample.log"/>
  <layout type="log4net.Layout.PatternLayout">
    <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
  </layout>
</appender>

<root>

  <level value="All"/>

  <appender-ref ref="LogFileAppender"/>
</root>

一切正常..但我需要的是从代码移动代码web.config并从文本文件中读取它.

另外我需要2级调试和错误..

谁能帮我这个？

谢谢

我想尝试从我的应用程序中记录一些应用程序消息.在这种情况下,我只想强迫nunit使用log4net.我在http://www.ofconsulting.com/PublicPortal/ofc-tech-blog/92-configure-log4net-with-nunit.html找到了一些例子.

log4net在app.config中配置如下:

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
  </configSections>

<log4net>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="LogFileAppender" />
    </root>
    <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
      <param name="File" value="log.txt" />
      <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>

在我的测试代码中是如下

[TestFixture]
class DomainTests
{
    protected static readonly ILog log = LogManager.GetLogger(typeof(DomainTests));
    public void LoggingTests()
    {            
        log4net.Config.XmlConfigurator.Configure(); 
    }

    [Test]
    public void BasicLogTest()
    {
        log.Error("write my log …
