[jira] [Comment Edited] (LOG4J2-398) DateLookup not parsed for
FastRollingFile appender
[ https://issues.apache.org/jira/browse/LOG4J2-398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763485#comment-13763485 ]

That isn't quite true. The fileName is resolved when the Appender is created. Variables with only a single '$' are resolved when then configuration file is processed, so fileName="log/$\{date:yyyyMMdd-HHmmss} - myApp.log" would work but the file name would always have the time when the configuration was processed. In that context I am not sure using a Date lookup makes much sense in a fileName attribute.

> Issue Type: Bug
> Components: Appenders

> I'm trying to create a Log4j2 configuration file that will create a log file using DateLookup so that the current date and time are in the filename (so it matches the logging used in our other products). This is what the appender configuration looks like:
> {code:borderStyle=solid|language=XML}
> <FastRollingFile name="Rolling" fileName="log/$${date:yyyyMMdd-HHmmss} - myApp.log" filePattern="log/$${date:yyyyMMdd-HHmmss} - myApp-%i.log">
> <immediateFlush>true</immediateFlush>
> <suppressExceptions>false</suppressExceptions>
> <PatternLayout>
> <pattern>%d %p %c{1.} [%t] $${env:USER} %m%n</pattern>
> </PatternLayout>
> <Policies>
> <OnStartupTriggeringPolicy />
> <SizeBasedTriggeringPolicy size="100 MB"/>
> </Policies>
> </FastRollingFile>
> {code}
> However when the log file is generated the filename is "${date". I've tried different variations and haven't been able to get this lookup to work at all.
