Hi All,   Subject: logback generates two log files i am using Rollingfile appender and Time based rolling policy for one of the app., it generates two files one with the log file (sample.log) and the other with yesterday's date (sample-2014-07-27.0.log). Appreciate if anybody help on this.   <appender name="ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender">   <if condition='property("logFolder").contains("log")'>    <then>     <file>${logFolder}/Sample/sample.log</file>    </then>    <else>     <file>sample.log</file>    </else>   </if>   <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">    <fileNamePattern>sreg-%d{yyyy-MM-dd}.%i.log</fileNamePattern>    <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">     <!-- or whenever the file size reaches 50MB -->     <maxFileSize>50MB</maxFileSize>    </timeBasedFileNamingAndTriggeringPolicy>   </rollingPolicy>   <encoder>    <pattern>[%d{ISO8601}] [%-18thread]  - %-25c{0}  - %-5p - %msg%n</pattern>   </encoder>  </appender>  On Tuesday, July 8, 2014 7:48 AM, Jeremy Kane <jkane001@gmail.com> wrote: That did the trick,  thanks!

You mention a size-based policy, but I only see a time-based policy in your config.

The following patterns should work for RollingFileAppender. The code snippets are based on the code you pasted, and I did not test them. Please let me know if they work for you.

Size-and-time-based rollover [1]

* rolling policy = new TimeBasedRollingPolicy()

* TimeBasedRollingPolicy.timeBasedFileNamingAndTriggeringPolicy = new SizeAndTimeBasedFNATP() * trigger policy = do not set (already handled by TimeBasedRollingPolicy) Code:

    TimeBasedRollingPolicy<ILoggingEvent> rollingPolicy = new TimeBasedRollingPolicy<ILoggingEvent>();     rollingPolicy.setMaxHistory(2);     rollingPolicy.setFileNamePattern(fileDirectory + "/log.%d.txt");     rollingPolicy.setParent(rollingFileAppender);     rollingPolicy.setContext(loggerContext);

    // size-and-time-based rollover (5MB files).     // We don't need to set this triggering policy's context or start     // it because RollingFileAppender.start() does all that for us.     // SizeAndTimeBasedFNATP.start() is relatively expensive, so do it     // only once if we can avoid it.     SizeAndTimeBasedFNATP<ILoggingEvent> triggerPolicy = new SizeAndTimeBasedFNATP<ILoggingEvent>();     triggerPolicy.setMaxFileSize("5MB");     rollingPolicy.setTimeBasedFileNamingAndTriggeringPolicy(triggerPolicy);

    rollingPolicy.start();

Size-based rollover [2] * rolling policy = new FixedWindowRollingPolicy()

* trigger policy = new SizeBasedTriggeringPolicy() Code:

    // size-based rollover (fixed window of 3 files, 5MB each)     FixedWindowRollingPolicy rollingPolicy2 = new FixedWindowRollingPolicy();     rollingPolicy2.setContext(loggerContext);     rollingPolicy2.setFileNamePattern("foo.%i.log");     rollingPolicy2.setMinIndex(1);     rollingPolicy2.setMaxIndex(3);     rollingPolicy2.start();

    // size-based rollover needs a triggering policy     SizeBasedTriggeringPolicy<ILoggingEvent> triggerPolicy2 = new SizeBasedTriggeringPolicy<ILoggingEvent>();     triggerPolicy2.setContext(loggerContext);     triggerPolicy2.setMaxFileSize("5MB");     triggerPolicy2.start();

I've been trying to get the rollinglogfileappender to roll-over at a certain file size, but I've had no luck.  I can get it to roll over at midnight each night, but I still would prefer to either combine them or have it just be file-size limited.

...

My config is such:

// Rolling Log Appender String fileDirectory = KanetikApplication.getFileDirectory(context);

RollingFileAppender<ILoggingEvent> rollingFileAppender = new RollingFileAppender<ILoggingEvent>(); rollingFileAppender.setContext(loggerContext); rollingFileAppender.setAppend(true); rollingFileAppender.setFile(fileDirectory + "/log.txt");

TimeBasedRollingPolicy<ILoggingEvent> rollingPolicy = new TimeBasedRollingPolicy<ILoggingEvent>(); rollingPolicy.setMaxHistory(2); rollingPolicy.setFileNamePattern(fileDirectory + "/log.%d.txt"); rollingPolicy.setParent(rollingFileAppender); rollingPolicy.setContext(loggerContext); rollingPolicy.start();

rollingFileAppender.setRollingPolicy(rollingPolicy);

PatternLayoutEncoder fileEncoder = new PatternLayoutEncoder(); fileEncoder.setContext(loggerContext); fileEncoder.setPattern("%d{h:mm:ss} %level - %msg%n"); fileEncoder.start();

rollingFileAppender.setEncoder(fileEncoder); rollingFileAppender.start();

// LogCat Appender PatternLayoutEncoder logcatEncoder = new PatternLayoutEncoder(); logcatEncoder.setContext(loggerContext); logcatEncoder.setPattern("%msg%n"); logcatEncoder.start();

PatternLayoutEncoder tagEncode = new PatternLayoutEncoder(); tagEncode.setContext(loggerContext); tagEncode.setPattern(tag); tagEncode.start();

LogcatAppender logcatAppender = new LogcatAppender(); logcatAppender.setContext(loggerContext); logcatAppender.setEncoder(logcatEncoder); logcatAppender.setTagEncoder(tagEncode); logcatAppender.start();

// add the newly created appenders to the root logger; // qualify Logger to disambiguate from org.slf4j.Logger ch.qos.logback.classic.Logger root = (ch.qos.logback.classic.Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);

root.setLevel(level); root.addAppender(rollingFileAppender); root.addAppender(logcatAppender);

Can anyone tell me why it's not working?
