-----------------------------------
Summary: 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
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}
It appears to me that it was about to use the failover appender, however it did
not start properly due to the parsing error.
