Hello, I have following logback rolling file appender configuration: <appender name="DWHTextToolActionLogger" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${user.home}/data/inbound/csi/text_approval/xxx_text_approval.csv</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${user.home}/data/inbound/csi/text_approval/xxx_text_approval_%d{yyyy_MM_dd}.csv.gz</fileNamePattern> <maxHistory>100</maxHistory> </rollingPolicy> <encoder> <pattern>%m%n</pattern> </encoder> </appender> <logger name="DWHTextToolActionLogger" additivity="false"> <level value="INFO" /> <appender-ref ref="DWHTextToolActionLogger" /> </logger> I would expect the log file to roll nightly, however, I only see following files: -rw-r--r-- 1 xxx xxx 236K Jun 28 14:08 xxx_text_approval.csv -rw-r--r-- 1 xxx xxx 39K Jun 22 08:21 xxx_text_approval_2011_06_21.csv.gz -rw-r--r-- 1 xxx xxx 32K Jun 23 08:18 xxx_text_approval_2011_06_22.csv.gz -rw-r--r-- 1 xxx xxx 35K Jun 24 07:52 xxx_text_approval_2011_06_23.csv.gz -rw-r--r-- 1 xxx xxx 26K Jun 25 07:43 xxx_text_approval_2011_06_24.csv.gz -rw-r--r-- 1 xxx xxx 41K Jun 26 07:50 xxx_text_approval_2011_06_25.csv.gz -rw-r--r-- 1 xxx xxx 28K Jun 27 07:44 xxx_text_approval_2011_06_26.csv.gz -rw-r--r-- 1 xxx xxx 57K Jun 28 08:12 xxx_text_approval_2011_06_27.csv.gz Is it misconfigured, or does the rolling actually happens at the first log message in the morning? If it's action based, how can i configure rolling to be triggered @midnight no matter how empty or full the log is? regards Leon p.s. version: <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>0.9.28</version>
