Question

I have this code in my Config.groovy:

    appenders {
        console name: "stdout", layout: pattern(conversionPattern: "%c{2} %m%n")
    }

    root {
        warn 'stdout'
    }

Now I want to log messages with DEBUG level from a specific controller (or specific package). How can I achieve that?

Answer 1

If your controller name is ExampleController in the com.example package, add this to the log4j closure in your Config.groovy:

debug 'grails.app.controllers.com.example.ExampleController'

See the Grails user guide for more logging examples.
