log rollover should be configurable using %d multiple times in file name pattern -------------------------------------------------------------------------------- Key: LBCORE-242 URL: http://jira.qos.ch/browse/LBCORE-242 Project: logback-core Issue Type: Improvement Components: Rolling Affects Versions: 1.0.0 Reporter: Thomas Corte Assignee: Logback dev list Trying to configure a log rollover with logs being *rolled daily* and put into a directory named "yyyy-MM", i.e. one folder for each *month* containing that month's logs, I'm using the following appender config: {noformat} <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>app.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- rollover every minute --> <fileNamePattern%d{yyyy-MM}/app.%d{yyyy-MM-dd}.log</fileNamePattern> </rollingPolicy> <encoder> <pattern>%d{"yyyy-MM-dd HH:mm:ss,SSS"} [%thread] %-5level %logger{36} - %msg%n%xEx</pattern> </encoder> </appender> {noformat} However, it seems as if the current logback implementation merely considers the first %d specification, which leads to a log rotation only once per month instead of the desired once per day frequency. I figure this is because via %d, the log rotation frequency and the file name pattern are somewhat tied together and seemingly can't be specified independently. It would be nice if either multiple %d specifiers would be supported, with an option to specify which one should be considered for the rollover period. Even better, it might be a good idea to support the rollover period to be specified separately and independently from the file name pattern; arguably, using the file name patterns for both is somewhat convenient, but violates the principle of "separation of concerns". -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
