Hi all, I'm tearing my hairs off to understand why the RollingFileAppender in my configuration doesn't behave as expected. I'm using logBack 0.9.15 version with jboss 5.1 EAP. My configuration file is below with few remarks: 1) The fileNamePattern I've set (in bold) is supposed to create a new file file each minute. 2) I've set layout instead of an encoder (which is in pattern) because encoder in not supported in this version of logback. When I start the server the output seem to be ok with my configuration and a log file named tpm-ws.log is created as expected. After one day of testing, there is no other file created. All logs are still generated in the same file. Can someone explain me what's wrong in my configuration? Is the RollingFileAppender supported in the 0.9.15 version. <configuration debug="true" scan="true"> <property name="tpm-log-file" value="C:\\Developpement\\jboss\\jboss-5.1.0.GA\\server\\default\\conf\\confwspatio\\logs\\tpm-ws.log" /> <appender name="TPM-WS-LOG" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${tpm-log-file}</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- un nouveau fichier par jour --> <fileNamePattern>logFile.%d{yyyy-MM-dd-HHmm}.log</fileNamePattern> <!-- garde un historique de 30 jours --> <maxHistory>30</maxHistory> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <maxFileSize>1MB</maxFileSize> </triggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{dd/MM/yyyy HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern> </layout> <!-- <encoder> <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> </encoder> --> </appender> <root level="TRACE"> <appender-ref ref="TPM-WS-LOG" /> </root> <logger name="org.springframework" level="TRACE"> <appender-ref ref="TPM-WS-LOG" /> </logger> </configuration> Thanks in advance.
