Hi there,
I tried to configure a SizeAndTimeBasedRollingPolicy programmatically (see below)
Logger statisticsLogger = (Logger) LoggerFactory.getLogger("statistics");
int MAX_HISTORY = 1095;
FileSize MAX_FILE_SIZE = FileSize.valueOf("250MB"); private static final String PATTERN = "%d %-5level %logger %msg%n";
LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
String filename = "log/"+applicationContext.serviceGroupKey()+"-statistics.log";
String rollingFilenamePattern="log/"+applicationContext.serviceGroupKey()+"statistics-%d{yyyy-MM-dd_HH}.log.gz";
PatternLayoutEncoder patternLayoutEncoder = new PatternLayoutEncoder();
patternLayoutEncoder.setPattern(PATTERN);
patternLayoutEncoder.setContext(loggerContext);
patternLayoutEncoder.start();
RollingFileAppender<ILoggingEvent> rollingFileAppender = new RollingFileAppender<ILoggingEvent>();
rollingFileAppender.setFile(filename);
rollingFileAppender.setName("statistics");
rollingFileAppender.setEncoder(patternLayoutEncoder);
rollingFileAppender.setContext(loggerContext);
rollingFileAppender.setImmediateFlush(true);
rollingFileAppender.setAppend(false);
patternLayoutEncoder.setParent(rollingFileAppender);
SizeAndTimeBasedRollingPolicy<Object> rollingFilePolicy = new SizeAndTimeBasedRollingPolicy<>();
// TimeBasedRollingPolicy<Object> rollingFilePolicy = new TimeBasedRollingPolicy<>();
rollingFilePolicy.setContext(loggerContext);
rollingFilePolicy.setParent(rollingFileAppender);
rollingFilePolicy.setFileNamePattern(rollingFilenamePattern);
rollingFilePolicy.setMaxHistory(MAX_HISTORY);
rollingFilePolicy.setMaxFileSize(MAX_FILE_SIZE); // comment out for TimeBasedRollingPolicy
rollingFilePolicy.start();
rollingFileAppender.setRollingPolicy(rollingFilePolicy);
rollingFileAppender.start();
statisticsLogger.addAppender(rollingFileAppender);
statisticsLogger.setAdditive(false);
However, no logfile is produced. If the SizeAndTimeBasedRollingPolicy is replaced by a TimeBasedRollingPolicy, everything works fine.
What is my mistake.
Thanks in advance
