Dear sir/madam, I am a university student trying to create a software related to my coursework and 1 of the requirements is that the output of logback file will rollover to new files every 5 minutes. I am unable to find a solution to this and i tried to use the periodictimebasedfilenamingandtriggeringpolicy. I cannot get any msg out of it. Here is my configuration in the xml when i use periodictimebasedfilenamingandtriggeringpolicy : <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="rsms.rolling" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>d:\\log\\RSMS\\RSMS.txt</file> <ImmediateFlush>true</ImmediateFlush> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- rollover daily --> <fileNamePattern>d:\\log\\RSMS\\BK\\RSMS-%d{yyyy-MM-dd_HHmm}.%i.txt</fileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.PeriodicTimeBasedFileNamingAndTriggeringPolicy"> <period>600</period> </triggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{yyyyMMdd HHmmss.SSS} [%-5level]%msg%n</Pattern> </layout> </appender> <logger name="lol" level="debug" additivity="false"> <appender-ref ref="rsms.rolling" /> </logger> </configuration>
