Adding Date & time Stamp in Log file name

[Yugandhar Ghanta]

Hi,
I am using Log4j. In configuration file(XML File), i am using RollingFileAppender... i am generationg output log file(AppINFO.log) based on maxFileSize property. Can i include or append Date pattern in output log file name dynamically.

 <appender name="INFOFILE" class="org.apache.log4j.RollingFileAppender">
    <param name="Threshold" value="INFo"/> 
    <param name="File" value="C:/temp/AppINFO.log"/> <!--Here i need to include date pattern in the file name-->
    <param name="Append" value="true"/>
    <param name="MaxFileSize" value="3000KB"/>
    <param name="maxBackupIndex" value="5"/> 
    <layout class="org.apache.log4j.PatternLayout"> 
<param name="ConversionPattern" value="%d %-5p [%c] %m%n"/> 
</layout>
</appender>   

In the above XML code...need to append Date pattern in file name, i.e:
<param name="File" value="C:/temp/AppINFO.<Year&Date>.log"/>
Can anyone please help me on this?
Thanks in advance,
Yugandhar.

You will probably need to use a custom appender.

I have not tried this out, but there is a code snippet and example configuration of a "Timestamp File Appender" on the log4j wiki's Useful Code section. It looks pretty old, so may need updating to use with a newer version of log4j.
