Answer 1

Coloring the Wildfly log in the Eclipse console :

1. Install the ANSI Escape in Console plugin from the Eclipse Marketplace : https://marketplace.eclipse.org/content/ansi-escape-console

2. You may have to remove the -Dorg.jboss.logmanager.nocolor=true VM argument from Wildfly server launch configuration. To remove it you:

   1. Go to the "Servers" tab
   2. Right click on the Wildlfy server
   3. Select Open menu entry
   4. In the displayed Overview tab, section General information, click on Open launch configuration
   5. In the Edit Configuration dialog, edit the VM arguments to remove -Dorg.jboss.logmanager.nocolor=true argument.
   6. Apply + OK

About the color mapping :

The default color mapping is as follow:

• error : darkred
• warn : yellow
• info : clear
• debug : green

Which gives the syntax error:darkred,warn:yellow,info:clear,debug:green .

The default color mapping is set in the org.jboss.logmanager.formatters.ColorMap class.

Answer 2

You can define a color map to assign a color to different log levels.

The format is a comma-separated list of LEVEL:COLOR.

• Valid levels: finest, finer, fine, config, trace, debug, info, warning, warn, error, fatal, severe
• Valid colors: black, green, red, yellow, blue, magenta, cyan, white, brightblack, brightred, brightgreen, brightblue, brightyellow, brightmagenta, brightcyan, brightwhite

Launch the jboss cli cmd

• on Linux jboss-cli.sh
• on windows jboss-cli.bat

location : C:\FileLocation\wildfly-17.0.0.Final\wildfly-17.0.0.Final\bin

then enter this cmd :

logging/pattern-formatter=PATTERN_FORMATTER_NAME:write-attribute(name=color-map,value="LEVEL:COLOR,LEVEL:COLOR")
