LogFileAppender在log4net的最大文件大小 [英] Maximum Filesize of LogFileAppender in Log4Net

问题描述

我使用log4net的，而现在，这是一个惊人的日志框架，尤其是当勾搭成Castle.Windsor。但是...

I am using Log4net for a while now and it's an amazing logging framework, especially when hooked into Castle.Windsor. However...

我平时使用的滚动文件附加目的地，但是这已经造成了太多的日志文件不是我真正想要的，所以不是，我的最新项目，已使用的基本LogFileAppender代替，但问题是日志文件不断增加（看似永远）。

I usually use the rolling file appender, but this has resulted in too many log files than I actually want, so instead, for my latest project, have used the basic LogFileAppender instead, but the problem is the log file keeps growing (seemingly forever).

我怎么能告诉Appender的不走了一个固定大小（并开始删除旧日志和追加新的文件吗？

How can I tell the appender to not go over a fixed size (and start removing old logs and appending the new ones to the file?

我现在的配置是这样的：

My current configuration looks like:

<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
  <file value="E:\Logs\iWater\Schedule-Dispatch-API.log"/>
  <param name="AppendToFile" value="true"/>
  <maximumFileSize value="2048KB"/>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%-16date{dd MMM HH:mm:ss} %-7level %-25.35logger{1} %message%newline"/>
  </layout>
</appender>

它似乎像maximumFileSize属性不被尊重。任何解决办法？

Its seems like the maximumFileSize attribute is not being respected. Any solutions?

另外，我怎么可以配置滚动文件附加器仅创建1个文件（永远）？

Alternatively, how can I configure the rolling file appender to only create 1 file (ever)?

推荐答案

在FileAppender类不具备MAXFILESIZE / MaximumFileSize性能。如果使用RollingFileAppender进行，你只能得到这些。下面是一个例子，这将限制你的文件到一个固定的最大大小，没有备份（设置maxSizeRollBackups为0）。请注意，当文件达到最大尺寸，它截断（基本上是删除所有现有的记录，并重新开始）：

The FileAppender class does not have the MaxFileSize/MaximumFileSize properties. You only get those if you use a RollingFileAppender. Here's an example that will limit your file to a fixed maximum size, with no backups (set maxSizeRollBackups to 0). Note that when the file reaches its max size, it truncates (basically deletes all existing logging and starts over):

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="log.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="0" />
    <maximumFileSize value="10MB" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
    </layout>
</appender>
