WildFly 8 Registration Levels

Question

How to change the logging levels of WildFly 8, in particular server.log. I currently suspect that they default to INFO and would like to change it to Debug or Error.

For reference, I studied these articles.

https://docs.jboss.org/author/display/WFLY8/Logging+Configuration

https://docs.jboss.org/author/display/WFLY8/How+To

And suspect it is right;

<subsystem xmlns="urn:jboss:domain:logging:2.0"> <console-handler name="CONSOLE"> <level name="DEBUG"/> <formatter> <named-formatter name="COLOR-PATTERN"/> 

Answer 1

By default, the console-handler parameter is set to INFO , and the FILE handler does not have a set of levels. The root-logger parameter is also set to INFO .

The instructions on the How to Link page are for you to add a new registrar through the CLI and assign a level to it. If you must add a new logger at the DEBUG level, then server.log will receive these log messages written on it.

If you want to change the root-logger to see DEBUG messages for all unregistered logisticians, you can run the following command.

 /subsystem=logging/root-logger=ROOT:write-attribute(name=level,value=DEBUG) 

If you want to also see messages on the console, you need to change the level on the handler.

 /subsystem=logging/console-handler=CONSOLE:write-attribute(name=level,value=DEBUG) 

I would not advocate the use of XML. Using a management interface such as the CLI or the web console is an appropriate way to change server settings.

Just change the level of the root registrar and console logger. For the first shot, this should work.
