How can I write username to log in Symfony2 - php

Question

I want to write username like extra field to production log.
How can I do it?
I have this config in config.yml:
services:
monolog.formatter.logprocessor:
class: Monolog\Formatter\LineFormatter
arguments:
- "[%%datetime%%] [%%username%%] %%channel%%.%%level_name%%: %%message%%\n"
monolog.processor.logprocessor:
class: Acme\CoreBundle\Monolog\LogProcessor
tags:
- { name: monolog.processor, method: processRecord }
monolog:
handlers:
main:
type: stream
path: "%kernel.logs_dir%/%kernel.environment%.log"
level: warning
formatter: monolog.formatter.logprocessor
When I tried inject security.context into LogProcessor, I get error:
[Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException]
Circular reference detected for service "monolog.processor.logprocessor", path: "router ->
monolog.logger.router -> monolog.processor.logprocessor -> security.context -> security.a
uthorization_checker -> security.authentication.manager -> security.user.provider.concrete
.chain_provider -> security.user.provider.concrete.main -> doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection -> monolog.logger.doctrine".

Here is the configuration
# Service Configuration
services:
monolog.formatter.html:
class: Monolog\Formatter\HtmlFormatter
monolog.processor.web_processor:
class: Monolog\Processor\WebProcessor
tags:
- { name: monolog.processor, method: __invoke }
monolog.processor.user:
class: Company\ToolBoxBundle\Services\Monolog\ExtraProcessor
arguments: ["#security.token_storage"]
tags:
- { name: monolog.processor }
- { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
And the service code
namespace Company\ToolBoxBundle\Services\Monolog;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class ExtraProcessor
{
private $tokenStorage = null;
private $user = null;
private $postParams = null;
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
}
public function __invoke(array $record)
{
if (null !== $this->user) {
$record['extra']['user'] = $this->user->getUserDetails();
}
if (null !== $this->postParams) {
$record['extra']['postParams'] = $this->postParams;
}
return $record;
}
public function onKernelRequest(GetResponseEvent $event)
{
$postParams = $event->getRequest()->request->all();
if(false === empty($postParams)){
$this->postParams = serialize($postParams);
}
if (null === $token = $this->tokenStorage->getToken()) {
return;
}
if (!is_object($user = $token->getUser())) {
// e.g. anonymous authentication
return;
}
$this->user = $user;
}
}

if you are using a symfony version >= 2.4, you can have a look at this bundle
that should help you doing what you want :)
