[jira] [Comment Edited] (LOG4J2-126) Failover appender doesn't fail
over on JMS Queue appender error
[ https://issues.apache.org/jira/browse/LOG4J2-126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13541600#comment-13541600 ]

------------------------------------------------------------
Actually, I suspect both case 1 and 2 are operating the same way. The difference is that when the connection is initially not available the appender tries to reconnect on every event. When the connection is initially available and fails it is not clearing the connection information and so keeps trying to send to the broken connection (which will fail) and then fails over to the failover.

> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.0-beta4
> Reporter: Szabolcs Beki
> Assignee: Ralph Goers
> Fix For: 2.0-beta4
>
>
> My goal is to send log messages via a JMS Queue unless the message broker is down, when I simple want send the logs to the Console.
> I configured a failover appender for this purpose:
> :
> <appenders>
> ...
> <JMSQueue name="LiffLog4j2Queue" queueBindingName="Log4j2Queue" factoryBindingName="QueueConnectionFactory"/>
> <Failover name="FailoverLiffLog4j2Queue" primary="LiffLog4j2Queue" suppressExceptions="false">
> <Failovers>
> <appender-ref ref="Console"/>
> </Failovers>
> </Failover>
> </appenders>
> <loggers>
> <root level="debug">
> <appender-ref ref="FailoverLiffLog4j2Queue"/>
> </root>
> All works as expected when the message broker is up.
> When I shut down the message broker while running my application, instead of the log message I get this message to my console :
> 2012-11-21 21:51:15,726 ERROR Could not publish message via JMS JMSQueue:QueueConnectionFactory.Log4j2Queue
> Using a failover appender I expected to get the log messages on the console.
> Also tried to start my application without ever starting message broker. In this case it correctly fails to connect :
