Simultaneous support of %d and %i --------------------------------- Key: LBCORE-86 URL: http://jira.qos.ch/browse/LBCORE-86 Project: logback-core Issue Type: Bug Components: Appender Affects Versions: 0.9.14 Reporter: Neil Lott Assignee: Logback dev list Hello Neil, FileNamePattern does not support the %d when used within FixedWindowRollingPolicy. Only %i is supported. It's a currentlimitation of the code. I suggest that you enter a jira issue requesting simultaneous support for %d and %i. Referencing or copying this thread would set a context for the problem which would be helpful.
