Logging 最近10天的JBoss日志备份

要求：我们使用JBoss-5.1.0.GA应用服务器来托管我们的应用程序。我想每天轮换我的日志，并保留过去10天日志文件的历史记录

  <!-- Rollover at the top of each hour
  <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
  -->

  <layout class="org.apache.log4j.PatternLayout">
     <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

     <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
     <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
    -->
  </layout>

当前情况：目前日志每天都在滚动，但它只保留最后一天文件的历史记录。我需要保存日志以备最后几天使用，而不是一天。下面是Jboss-log4j.xml中的xml片段

  <!-- Rollover at the top of each hour
  <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
  -->

  <layout class="org.apache.log4j.PatternLayout">
     <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

     <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
     <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
    -->
  </layout>

  <!-- Rollover at the top of each hour
  <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
  -->

  <layout class="org.apache.log4j.PatternLayout">
     <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

     <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
     <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
    -->
  </layout>

  <!-- Rollover at the top of each hour
  <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
  -->

  <layout class="org.apache.log4j.PatternLayout">
     <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

     <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
     <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
    -->
  </layout>

我意识到通过MaxBackUp Index使用它，但当我们使用DailRollingFileAppender时，它不起作用。请帮帮我

  <!-- Rollover at the top of each hour
  <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>

  <layout class="org.apache.log4j.PatternLayout">
     <!-- The default pattern: Date Priority [Category] (Thread) Message\n -->
        <param name="ConversionPattern" value="%d %-5p [%c] (%t) %m%n"/>

     <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
     <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
    -->
  </layout>
