Send StatusLogger output to Syslog appender
Hello,
How do I configure log4j2 to send StatusLogger output to a Syslog appender?
Our application runs on several instances and logs to a remote instance for
centralised logging, however status logging only appears in the logs on
each instance.
Thank you,
/David

StatusLogger was not meant for that kind of flexibility as it is for diagnostics of the logging system.
While in theory it would be possible to create a StatusListener that binds to an Appender I don’t believe it would be simple. Plus, it couldn’t use Plugins to be configured. Frankly, it would probably be easier to build a specific StatusListener for a specific Appender that uses the Appender’s Manager.

Re: Send StatusLogger output to Syslog appender

Using a “regular” logger to log the internals of the logging system is a very bad idea. I can imagine all kinds of problems, which is why Log4j uses an internal mechanism for status logging.
If the new Configuration contains invalid XML the reconfiguration will fail and the old configuration will remain in effect.

Re: Send StatusLogger output to Syslog appender
Posted by David KOCH <dk...@ezakus.com>.
Hello,
Thank you for your answers. I gather this is not possible purely by
configuring log4j2?
I could implement a ConfigurationListener which logs changed configurations
to a regular logger but how would that re-act if the new configuration
contains some invalid XML? The StatusLogger supplies some feedback in that
cases.
Regards,
/David

Ralph,
I fine point I missed, thank you.
Would it be too weird to provide a bridge StatusListener that forwards to
an Appender or to all of Log4j?

Gary,
This is the StatusLogger. Messages are via StatusListeners. The only one we provide is the StatusConsoleListener. If a user wants to do something else they need to implement their own StatusListener and register it.
