log4j2默认过渡策略不删除日志 [英] log4j2 Default rollover strategy not deleting logs

问题描述

我的log4j2设置了默认的过渡策略，如下所示-

I have log4j2 with a default rollover strategy set up like this -

<RollingFile name="RollingFile" fileName="cc" filePattern="logs/${baseFileName}-%d{yyyy-MM-dd}.log.gz">
        <PatternLayout>
            <pattern>%d{dd/MMM/yyyy HH:mm:ss,SSS}- %c{1}: %m%n</pattern>
        </PatternLayout>
        <Policies>
            <TimeBasedTriggeringPolicy interval="1" modulate="true" />
        </Policies>
        <DefaultRolloverStrategy>
            <Delete basePath="logs/">
                <IfFileName glob="logs/${baseFileName}-*.log" />
                <IfLastModified age="2d" />
            </Delete>
        </DefaultRolloverStrategy>
    </RollingFile>

所以当正确使用超过2天时，应该删除最早的文件吗?

so it should be deleting the oldest files when it gets to over 2 days old correct?

我的日志文件存储在项目的基本路径中的日志文件中.

my log files are stored in the base path of the project in a folder called logs..

但是我只是进行了一次测试，在停止它之前它已经达到了5个文件....

however I just did a test run and it got to 5 files before I stopped it....

你知道是什么原因造成的吗?

any idea what could be causing this?

推荐答案

请检查以下配置以删除旧文件: DefaultRolloverStrategy max ="10"表示每天最多可以创建10个文件. 您可以使用IfAccumulatedFileCount超出="2"来控制始终存在多少个文件. 将指定文件的使用期限，如果文件总数大于2(如IfAccumulatedFileCount中所指定)，则从今天起2天之前的文件将被删除.

Please check the below configuration for deleting old files: DefaultRolloverStrategy max="10" means daily 10 files can be created max. You can use IfAccumulatedFileCount exceeds="2" to control how many files will be present at all time. will specify the age of the file, the files older than 2 days from present day will be deleted if the total number of files are grater than 2 (as specified in IfAccumulatedFileCount ).

<DefaultRolloverStrategy max="100">
<Delete basePath="${baseDir}" maxDepth="2">
  <IfFileName glob="*/app-*.log">
    <IfLastModified age="2d">
      <IfAny>
        <IfAccumulatedFileCount exceeds="2" />
      </IfAny>
    </IfLastModified>
  </IfFileName>
</Delete>

也许它在错误的路径中搜索要删除的文件，或者您的日志文件存在时间不到2天. 您正在使用哪个版本的log4j?它将适用于Log4j-2.5及更高版本

Maybe it is searching the file to delete in the incorrect path or your log files are not 2 day old. which version of log4j you are using? it will work for Log4j-2.5 and above
