Más fácil de depurar

Más niveles de verbosidad
$ php app/console foo --verbose=1 # -v
$ php app/console foo --verbose=2 # -vv
$ php app/console foo --verbose=3 # -vvv

class MyCommand extends Command
{
protected function execute($input, $output)
{
$verbosity = $output->getVerbosity();
if ($verbosity === OutputInterface::VERBOSITY_VERBOSE)
{
$output->writeln("Información");
}
if ($verbosity === OutputInterface::VERBOSITY_VERY_VERBOSE)
{
$output->writeln("Más información");
}
if ($verbosity === OutputInterface::VERBOSITY_DEBUG)
{
$output->writeln("Mucho más información");
}
}

parámetros de conﬁguración
$ console container:debug --parameters
$ console container:debug --parameter=kernel.debug

stack trace en texto plano

más información en router:match
$ php app/console router:match /demo/hello/fabien
Route "_demo_hello" matches
[router] Route "_demo_hello"
Name _demo_hello
Path /demo/hello/{name}
Host ANY
Scheme ANY
Method ANY
Class SymfonyComponentRoutingRoute
Defaults _controller: AcmeDemoBundleController
DemoController::helloAction
Requirements NO CUSTOM
Options compiler_class: SymfonyComponentRoutingRouteCompiler
