Hi Jan-Olav,
Your programmatic configuration of RollingFileAppender in conjunction
with TimeBasedRollingPolicy+SizeAndTimeBasedFNATP looks good. Most
users have a hard time with such programmatic configuration.
The other files, i.e. trace-2013-03-13-16.12.{1,2,3}, should have been
removed as well. Which version of logback are you using?

Hello, using the following programmatic configuration there seems to
be a problem with how the maxHistory argument is implemented.
I roll over multiple times withing the time interval (every minute
here), creating the following files : (maxHistory = 3)
trace.log (active file)
trace-2013-03-13-16.14.0.log.zip
trace-2013-03-13-16.13.0.log.zip
trace-2013-03-13-16.12.2.log.zip
trace-2013-03-13-16.12.1.log.zip
trace-2013-03-13-16.12.0.log.zip
The nex time rollover occurs, the 16.13.0.log.zip file is removed, and
not the oldest ones (12.{1,2,3} as I would have expected. Is this
intended behaviour ?
Or is it a problem with my configuration ?
public static Logger createTimeAndSizeRollingLogger(String fileBase,
String maxSize, int maxHistory, String resolutionPattern) {
LoggerContext loggerContext = (LoggerContext)
LoggerFactory.getILoggerFactory();

RollingFileAppender<ILoggingEvent>();
appender.setContext(loggerContext);
appender.setFile(fileBase + ".log");

timePolicy.setFileNamePattern(fileBase + "_%d{" +
resolutionPattern + "}-%i.log.zip");
timePolicy.setContext(loggerContext);
timePolicy.setMaxHistory(maxHistory);
timePolicy.setParent(appender);
appender.setRollingPolicy(timePolicy);

rollingPolicy.setMaxFileSize(maxSize);
rollingPolicy.setTimeBasedRollingPolicy(timePolicy);
rollingPolicy.setContext(loggerContext);
timePolicy.setTimeBasedFileNamingAndTriggeringPolicy(rollingPolicy);
timePolicy.start();
rollingPolicy.start();
PatternLayoutEncoder encoder = new PatternLayoutEncoder();
encoder.setContext(loggerContext);
encoder.setPattern("%msg%n");
encoder.start();
appender.setEncoder(encoder);
appender.start();
Logger logger = loggerContext.getLogger(fileBase);
logger.setLevel(Level.TRACE);
logger.addAppender(appender);
StatusPrinter.print(loggerContext);
return logger;
}
