> -------------------------------------------------------
>
> Key: LOG4J2-1134
> URL: https://issues.apache.org/jira/browse/LOG4J2-1134
> Project: Log4j 2
> Issue Type: Question
> Components: Appenders
> Affects Versions: 2.4
> Reporter: Hüseyin Kartal
> Priority: Minor
>
> Hi,
> we use primary the SocketAppender to send log messages to a server instance.
> For failover purpose we defined a FailoverAppender with a
> RollingRandomAccessFileAppender as the failover instance.
> Following the configuration:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration monitorInterval="0" strict="true" name="XMLConfig"
> status="fatal" shutdownHook="enable"
> xmlns="http://jakarta.apache.org/log4j2/config";
> xmlns:events="http://jakarta.apache.org/log4j2/events";
> xmlns:levels="http://jakarta.apache.org/log4j2/levels";

> <Appenders>
> <Appender type="Socket" name="OUT-SOCKET"
> host="${sys:log.host}" port="${sys:log.port}" protocol="${sys:log.protocol}"

> </Appender>
> <Appender type="Failover" name="OUT-FAIL" primary="OUT-SOCKET">
> <Failovers>
> <Appender type="RollingRandomAccessFile"
> name="OUT-FILE" fileName="${file.name.tmp}${file.suffix}"
> filePattern="${file.name.tmp}-%2i${file.suffix}" ignoreExceptions="false">
> <Layout Type="PatternLayout"
> Pattern="${pattern.single}" />
> <Policies>

> </Policies>
> <DefaultRolloverStrategy
> max="${defaultRolloverStrategy.max}" fileIndex="min" />
> </Appender>
> </Failovers>
> </Appender>
> <Async name="ASYNC-OUT-FAIL">
> <AppenderRef ref="OUT-FAIL" />
> </Async>
> </Appenders>
> <Loggers>
> <asyncRoot level="all">
> <AppenderRef ref="ASYNC-OUT-FAIL" />
> </asyncRoot>
> <asyncLogger name="com" level="error" />
> <asyncLogger name="org" level="error" />
> <asyncLogger name="javax" level="error" />
> </Loggers>
> </Configuration>
> {code}
> Question: The appender OUT-FILE with the corresponding file is created on
> startup. Is it possible to create this file or the Appender only if a
> failover issue occurs?
