Issue/Introduction

On LiveUpdate Administrator (LUA) 2.3.x, I hope to check the LUA application log (lua-application.log). But the log files are rotated soon.
How to change the setting the log rotation based on daily?

Resolution

In LUA 2.3.8 this feature is managed by log4j.xml located under \Symantec\LiveUpdate Administrator\tomcat\webapps\lua\WEB-INF\classes\ . The first section section of the file will contain by default  :

<RollingFile name="ROLL" filePattern="D:/Program Files (x86)/Symantec/LiveUpdate Administrator/logs/lua-application-%i.log" fileName=/Program Files (x86)/Symantec/LiveUpdate Administrator/logs/lua-application.log">

<PatternLayout>
<Pattern>%d [%t] %-5p %c{2} %x - %m%n</Pattern>
</PatternLayout>

<Policies>
<SizeBasedTriggeringPolicy size="5 MB"/>
</Policies>
<DefaultRolloverStrategy max="50"/>
</RollingFile>

 

org.apache.log4j.RollingFileAppender class rotates the lua-application.log with MaxFileSize.

To change the daily based rotation, please use org.apache.log4j.DailyRollingFileAppender class and param name="DatePattern" like following;

<appender name="ROLL" class="org.apache.log4j.DailyRollingFileAppender">
  <param name="Threshold" value="DEBUG"/>
  <param name="File" value="C:/Program Files (x86)/Symantec/LiveUpdate Administrator//logs/lua-application.log"/>
  <param name="DatePattern" value="'.'yyyy-MM-dd"/>
  <layout class="org.apache.log4j.PatternLayout">

lua-application.log will be rotated

lua-application.log.yyyy-mm-dd

Note: The rotated files are not removed automatically. And the log files will be big.
