[logback-user] Adding a timestamp to a FileAppender file

[Lang, Johannes]

Hi Nicolas,
 
as far as i understand your goal, a RollingFileAppender would do the job.
The following appender is an example of a RollingFileAppender, which does
a Rollover every hour with de defined name-pattern. The rollover-policy is
defined by the time-pattern:
 
<appender name="RollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
	<File>logFile.log</File>
	<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
		<FileNamePattern>logFile.%d{yyyy-MM-dd_HH}.log</FileNamePattern>
	</rollingPolicy>
	<layout class="ch.qos.logback.classic.PatternLayout">
		<Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
	</layout>
</appender> 

cheers
Hannes

	Hi,
	
	I have just switched from log4j to logback. I would like to generate log containing results output by my program, and I want the file name to be SomePrefix.<timestamp>.someExt. I can do this programmatically but I'd like, if possible, to have all my logging configuration in my logback.xml file. Here's the appender I declared :
	
	<appender name="resultFile" class="ch.qos.logback.core.FileAppender">
	        <file>${logFolder}/SomePrefix.%d.someExt</file>
	        <append>false</append>
	        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
	            <level>info</level>
	        </filter>
	        <layout class="ch.qos.logback.classic.PatternLayout">
	            <pattern>%m%n</pattern>
	        </layout>
	    </appender> 
	
	However the %d pattern is not interpreted, is there a way to do this? Maybe using a RollingFileAppender, but I don't see how.
	
	Regards,
	Nicolas
