> Key: LOG4J2-1928
> URL: https://issues.apache.org/jira/browse/LOG4J2-1928
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.8.1
> Reporter: Lucas Ventura Carro
> Assignee: Ralph Goers
> Fix For: 2.9
>
>
> Following the docs about
> [RollingRandomAccessFileAppender|https://logging.apache.org/log4j/2.x/manual/appenders.html#RollingRandomAccessFileAppender]
> with a [DirectWrite
> rollover|https://logging.apache.org/log4j/2.x/manual/appenders.html#RolloverStrategies],
> the config should be:
> {code}
> <RollingRandomAccessFile append="true" filePattern="application.log.%i"
> name="json-log">
> <filters>
> <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
> </filters>
> <PatternLayout>
> <Pattern>%m%n</Pattern>
> </PatternLayout>
> <Policies>
> <SizeBasedTriggeringPolicy size="10 MB"/>
> </Policies>
> <DirectWriteRolloverStrategy maxFiles="10"/>
> </RollingRandomAccessFile>
> {code}
> But then console shows:
> {noformat}
> 2017-06-01 14:31:04,396 main ERROR No filename was provided for FileAppender
> with name json-log
> 2017-06-01 14:31:04,406 main ERROR Null object returned for
> RollingRandomAccessFile in appenders.
> 2017-06-01 14:31:04,417 main ERROR Unable to locate appender "json-log" for
> logger config "root"
> {noformat}
> If adding a {{fileName}} parameter, the logger can be used but the file is
> not rolling (same as LOG4J2-1906).
