Hi Logback users! I would like to store daily log files in the format: /logs/%d{yyyy/MM}/app.%d{yyyyMMdd}.log So that the end result is: /logs/2012/02/app.20120228.log That is I would like all daily log files for a given month in a single directory but each log file containing the full date. However, when I configure this filename pattern using ch.qos.logback.core.rolling.TimeBasedRollingPolicy, logback bases the rolling policy only on the first pattern: INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - The date pattern is 'yyyy/MM' from file name pattern '/logs/%d{yyyy/MM}/app.%d{yyyyMMdd}.log'. INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Rollover at start of every month. Is it possible to accomplish this, even by just forcing the rollover to be daily (at midnight) independent of the filename pattern? I have looked through the mailing lists, documentation, and source code and cannot figure out how or if it can be done. Thanks, Chris Lemper
