Decorate the $log service with context.

app.controller('LogExampleCtrl', function($scope, $log) {

    // Set the instance of the logger

    $log = $log.getInstance("LogExampleCtrl");

    // Try the enhanced $log service
    
    $log.log("Enter controller");

    $scope.executeLog = function() {
        $log.log("Button clicked !");
    }
});
