log4j2-保留日志文件的最后7天 [英] log4j2 - keep last 7days of log file

问题描述

要保留最近3天的日志文件，每个文件大小不超过10MB，如何在log4j2.yml文件中配置?

To keep the last 3days of log file with each file size up to 10MB, how to configure in log4j2.yml file?

我试过了，

filePattern: ${log}/${app}-archive/${app}-%d{MM-dd-yyyy}-%i.log"
...
Policies:
  TimeBasedTriggeringPolicy:
   interval: 1
   modulate: true
  SizeBasedTriggeringPolicy:
   size: 10 MB
 DefaultRolloverStrategy:
   delete:
    basePath: "${log}/${app}-archive"
    maxDepth: 1
    IfFileName:
     glob: "*.log"
    IfLastModified:
     age: 3d

，即使当天是今天的日志，它最多只能在同一天创建7个归档文件并删除旧文件.如果lastModified<是否有办法保存尽可能多的文件.3d?例如app-04-09-2021-8.log，app-04-09-2021-9.log，.... app-04-09-2021-39.log等.

and it creates only up to 7 archives on the same day and delete old files even though it was today's log. Is there a way to keep as much as files if its lastModified < 3d? like app-04-09-2021-8.log, app-04-09-2021-9.log,....app-04-09-2021-39.log and so on.

请指导我.

推荐答案

默认情况下， DefaultRolloverStrategy 最多保留 max 配置属性的值， 7默认情况下，根据您的用例，每天一次，基于时间的过渡间隔，如文件模式中所示， $ {app}-％d {MM-dd-yyyy}-％i.log - max 属性仅适用于％i 计数器.

By default DefaultRolloverStrategy will keep at most the value of the max configuration attribute, 7 by default, per time based rollover interval, daily in your use case as indicated in your file pattern, ${app}-%d{MM-dd-yyyy}-%i.log - the max attribute only applies only to the %i counter.

为该属性提供更大的值，您认为适当的值取决于您的日志模式.例如:

Provide a bigger value for that attribute, the value you consider appropriate depending on your log patterns. For example:

DefaultRollOverStrategy:
  max: 100
  delete:
    basePath: "${log}/${app}-archive"
    maxDepth: 1
    IfFileName:
     glob: "*.log"
    IfLastModified:
     age: 3d
