达到maximumFileSize时，log4net滚动文件追加程序文件名格式 [英] log4net rolling file appender file name format when maximumFileSize reached

问题描述

我们正在使用log4net滚动文件附加器，并且对我们的日志文件有以下要求:

We're using the log4net rolling file appender and have the following requirements for our log files:

• 每天开始时都有一个新的日志文件，文件名中带有日期
• 最大日志文件大小为500KB

我们遇到的问题是文件达到500KB时的文件命名策略:它们使用后缀.1重命名.这是有问题的，因为它破坏了Windows中的文件关联，因此(稍微)增加了琐碎的工作.

The issue we are having is the file naming strategy when files hit 500KB: they get renamed with a .1 suffix. This is problematic as it breaks file association in Windows, so opening the files is (slightly) more of a chore.

我们正在使用的配置是:

The configuration we're using is:

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="c:\log\path" />
  <staticLogFileName value="false" />
  <appendToFile value="true" />
  <rollingStyle value="Composite" />
  <datePattern value=".yyyy-MM-dd.lo\g" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <maxSizeRollBackups value="50" />
  <maximumFileSize value="500KB" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %message%newline" />
  </layout>
</appender>

是否支持指定当文件命中maximumFileSize时使用的命名策略?

Is there support for specifying the naming strategy used when our files hit the maximumFileSize?

推荐答案

log4net的1.2.11版包含

Version 1.2.11 of log4net includes the PreserveLogFileNameExtension property on the RollingFileAppender. Setting the property to true will allow files to be rolled in the format logName.roll#.fileExt, keeping your file associations intact.

appender块中的条目如下所示:
<param name="PreserveLogFileNameExtension" value="true" />

The entry inside the appender block would look like:
<param name="PreserveLogFileNameExtension" value="true" />
