WildFly CLI - Configuring Logging

Internal

• CLI Operations

Configure a New Logger

Add the Logger

Navigate to the appropriate logging subystem ("/subsystem=logging" in standalone mode and "/profile=.../subsystem=logging" in domain mode.

./logger=new-logger:add

Example:

./logger=org.hornetq:add

Configure the Logging Level on the Logger

From the same "directory"

./logger=new-logger:write-attribute(name="level", value="level") 

Example:

/logger=org.hornetq:write-attribute(name="level", value="TRACE")

Reconfiguring Logging to TRACE

Configure the ROOT Logger

cd <...>/subsystem=logging
./root-logger=ROOT:write-attribute(name=level,value=TRACE)

Configure the Handler

The actual handler who is supposed to write TRACE data may vary, in this case is the size-rotating-file-handler:

cd <...>/subsystem=logging
./size-rotating-file-handler=FILE:write-attribute(name=level,value=TRACE)

Configure Specific Loggers

Configure the specific loggers that should produce TRACE info, as shown here:

Enable CONSOLE logging

/subsystem=logging/console-handler=CONSOLE:add(level=INFO,formatter="%K{level}%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n")
/subsystem=logging/root-logger=ROOT:add-handler(name="CONSOLE")
