Dear all: I have the following configuration: String filename = "notification" appender("FILE", RollingFileAppender) { file = (jbossHomeDir ? jbossHomeDir + "/" : "") + "log/" + filename + ".log" rollingPolicy(TimeBasedRollingPolicy) { fileNamePattern = filename + ".%d{yyyy-MM-dd_HH-mm}.log" maxHistory = 30 } encoder(PatternLayoutEncoder) { pattern = logPattern } } I have it set to roll every minute just for testing. It appears that logback is recognizing my configuration correctly: 08:55:56,095 |-INFO in ch.qos.logback.classic.gaffer.ConfigurationDelegate@2d7d1491 - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 08:55:56,095 |-INFO in ch.qos.logback.classic.gaffer.ConfigurationDelegate@2d7d1491 - Naming appender as [FILE] 08:55:56,111 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 08:55:56,112 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern notification.%d{yyyy-MM-dd_HH-mm}.log for the active file 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - The date pattern is 'yyyy-MM-dd_HH-mm' from file name pattern 'notification.%d{yyyy-MM-dd_HH-mm}.log'. 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Roll-over every minute. 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Setting initial period to Thu May 26 08:55:27 EDT 2011 However, no rolling is happening. Ideas? Thanks, -- Eric
