如何配置RollingFileAppender根据日期和大小使用log4net滚动？ [英] How do I configure a RollingFileAppender to roll by date and size with log4net?

问题描述

我将log4net配置为使用复合RollingFileAppender，以便当前文件始终命名为 logfile.log ，所有后续文件均命名为 logfile-YYYY.MM.dd.seq.log 其中 seq 是日志在一天内超过特定大小的序列号。不幸的是，我在配置这样的设置方面没有成功。

编辑：

我的当前配置已粘贴到下面。它已经更新，基于几个答案，让我足够接近我的需要。这会生成以下格式的文件： logfile_YYYY.MM.dd.log.seq

 < log4net> ; 
 
< root> 
< level value =DEBUG/> 
< appender-ref ref =RollingFileAppender/> 
< / root> 
 
< appender name =RollingFileAppendertype =log4net.Appender.RollingFileAppender> 
< file value =logs\\logfile/> 
< staticLogFileName value =false/> 
< appendToFile value =true/> 
< rollingStyle value =Composite/> 
< datePattern value =_ yyyy.MM.dd& quot; .log& quot;/> 
< maxSizeRollBackups value =10/> 
< maximumFileSize value =75KB/> 
< layout type =log4net.Layout.PatternLayout> 
< conversionPattern value =％date [％thread]％-5级别％logger [％property {NDC}]  - ％message％newline/> 
< / layout> 
< filter type =log4net.Filter.LevelRangeFilter> 
< param name =LevelMinvalue =DEBUG/> 
< param name =LevelMaxvalue =FATAL/> 
< / filter> 
< / appender> 
 
< / log4net> 
  

一个有趣的注释，设置

 < staticLogFileName value =false/> 
  

为true将使记录器不写入任何文件。

解决方案

我们使用以下（在Log4J中）：

  appender name =rollerclass =org.apache.log4j.DailyRollingFileAppender> 
< param name =Filevalue =Applog.log/> 
< param name =DatePatternvalue ='。'yyyy-MM-dd/> 
< layout class =org.apache.log4j.PatternLayout> 
< param name =ConversionPatternvalue =[slf5s.start]％d {DATE} [slf5s.DATE]％n％p [slf5s.PRIORITY]％n％x [slf5s.NDC]％n ％t [slf5s.THREAD]％n％c [slf5s.CATEGORY]％n％l [slf5s.LOCATION]％n％m [slf5s.MESSAGE]％n％n/> 
< / layout> 
< / appender> 
  

这会给我们 Applog.log.yyyy-MM-dd / p>

I am configure log4net to use a composite RollingFileAppender so that the current file is always named logfile.log and all subsequent files are named logfile-YYYY.MM.dd.seq.log where seq is the sequence number if a log exceeds a certain size within a single day. Unfortunately, I have had very little success in configuring such a setup.

Edit:

My current configuration is pasted below. It has been updated based on several answers which gets me close enough for my needs. This generates files of the format: logfile_YYYY.MM.dd.log.seq

<log4net>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="RollingFileAppender" />
    </root>

    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="logs\\logfile"/>
        <staticLogFileName value="false"/>
        <appendToFile value="true"/>
        <rollingStyle value="Composite"/>
        <datePattern value="_yyyy.MM.dd&quot;.log&quot;"/>
        <maxSizeRollBackups value="10"/>
        <maximumFileSize value="75KB"/>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
        </layout>
        <filter type="log4net.Filter.LevelRangeFilter">
            <param name="LevelMin" value="DEBUG" />
            <param name="LevelMax" value="FATAL" />
        </filter>
    </appender>

</log4net>

One interesting note, setting

<staticLogFileName value="false"/>

to true causes the logger to not write any files.

解决方案

We use the following (in Log4J):

<appender name="roller" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="Applog.log"/>
    <param name="DatePattern" value="'.'yyyy-MM-dd"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[slf5s.start]%d{DATE}[slf5s.DATE]%n%p[slf5s.PRIORITY]%n%x[slf5s.NDC]%n%t[slf5s.THREAD]%n%c[slf5s.CATEGORY]%n%l[slf5s.LOCATION]%n%m[slf5s.MESSAGE]%n%n"/>
    </layout>
</appender>

This gives us Applog.log.yyyy-MM-dd files
