-----------------------------------
Assignee: Ralph Goers
> FailoverAppenders fail to start
> -------------------------------
>
> Key: LOG4J2-1973
> URL: https://issues.apache.org/jira/browse/LOG4J2-1973
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.8.2
> Reporter: Vina Martin
> Assignee: Ralph Goers
> Priority: Critical
>
> I created a simple Hello World program with Log4j2 2.8.2 following the
> documentation.
> {code}
> import org.apache.logging.log4j.LogManager;
> import org.apache.logging.log4j.Logger;
> public class HelloWorld {
> private static final Logger logger =
> LogManager.getLogger(HelloWorld.class);
> public static void main(final String... args) {
> logger.error("A test error- hello world!");
> }
> }
> {code}
> with the following configuration in {{log4j2.xml}}
> {code}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="WARN">
> <Appenders>
> <Console name="Console" target="SYSTEM_OUT">
> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level
> %logger{36} - %msg%n"/>
> </Console>
> <RollingFile name="RollingFile" fileName="logs/app.log"
> filePattern="logs/app-%d{MM-dd-yyyy}.log.gz"
> ignoreExceptions="false">
> <PatternLayout>
> <Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
> </PatternLayout>
> <TimeBasedTriggeringPolicy />
> </RollingFile>
> <Failover name="Failover" primary="RollingFile">
> <Failovers>
> <AppenderRef ref="Console"/>
> </Failovers>
> </Failover>
> </Appenders>
> <Loggers>
> <Root level="error">
> <AppenderRef ref="Failover"/>
> </Root>
> </Loggers>
> </Configuration>
> {code}
> I get this error when starting up my program: {{ERROR appender Failover has
> no parameter that matches element Failovers}}. I observed that the hello
> world message appeared in the log file and was properly appended each time I
> ran my hello world program.
> Then, I tried to simulate a scenario where a failover would happen to verify
> that the failover appender is not starting properly. I locked the log file to
> be read-only. After locking the file I ran the program and saw the following
> output:
> {code}
