Hi all,
I'm using log4j2 in a web app. I'm using RollingFileAppender and
monitorInterval.
The automatic reconfiguration fails with the following exception:
java.lang.IllegalStateException: Pattern does not contain a date
Steps:-
Change filePattern from "${web:rootDir}/server.%i.log" to
"${web:rootDir}/server.log.%d{yyyy-MM-dd}"
Remove <SizeBasedTriggeringPolicy size="2MB"/> from <Policies> and add
<TimeBasedTriggeringPolicy interval="1"/>
Save log4j2.xml
What I suspect?
The RollingFileManager sets the triggering policy first and then sets the
patternprocessor.
While setting the triggering policy, it uses the old pattern which does not
contain the RolloverFrequency. So, it throws IllegalStateException with the
message
"Pattern does not contain a date".
Possible solution?
In the updateData() of RollingFileManager, set the new pattern processor first
and then set the triggering policy.
I have also attached my log4j2.xml and the stacktrace of the error in the JIRA
ticket.
Please assist with the issue.
Thanks
