4.1.3 Logging
By default logging in Grails 3.0 is handled by the Logback logging framework and can be configured with the grails-app/conf/logback.groovy file.
| If you prefer XML you can replace the logback.groovyfile with alogback.xmlfile instead. | 
For more information on configuring logging refer to the Logback documentation on the subject.
