Juan Loman commented on LOG4J2-1185: ------------------------------------ I haven't been able to make this work in 2.8.2 (latest release as of this comment). Which kind of pattern should be used in the `fileName` property? I've tried with: {code} fileName="logs/current.$\{date:yyyy-MM-dd-HH-mm\}.log" {/code} asdf This should be described briefly in the official documentation. > Ability to change the fileName dynamically in RollingFileAppender > ----------------------------------------------------------------- > > Key: LOG4J2-1185 > URL: https://issues.apache.org/jira/browse/LOG4J2-1185 > Project: Log4j 2 > Issue Type: New Feature > Components: Appenders > Affects Versions: 2.1 > Reporter: Dhwaneet Bhatt > Assignee: Ralph Goers > Fix For: 2.8 > > > Right now RollingFileAppender rolls over the current file with fileName to > the one generated by FilePattern.
