how to pass username to rollbar via monolog, symfony2

Question

I am using rollbar.com to collect all details about exceptions in symfony2 app. However I don't understand how can I configure monolog so it would pass username and user id to rollbar.

I see that I can pass rollbar config as shown here and I am thinking person_fn is what I need. Still I don't know where to put this function (this should be in service because I need to check security token) and how to pass it to rollbar.

# config_prod.yml
rollbar:
    type: rollbar
    level: error
    token: %rollbar_token%
    config:
        person_fn: getUserForRollbarRightAboutNowOrSomething

Found solution:

update monolog/monolog bundle to at least 1.17.0 version.

create ContextProcessor and update user information

#src/AppBundle/Monolog/RollbarContextProcessor

namespace AppBundle\Monolog;

use AppBundle\Entity\User;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class RollbarContextProcessor
{
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function processRecord($record)
    {
        if ($this->tokenStorage->getToken()) {
            $user = $this->tokenStorage->getToken()->getUser();

            if ($user instanceof User) {
                $record['context']['payload']['person'] = [
                    'id' => $user->getId(),
                    'username' => $user->getUsername(),
                    'email' => $user->getEmail(),
                ];
            }
        }

        return $record;
    }
}

configure ContextProcessor as service with monolog.processor tag.

# app/config/config_prod.yml
services:
    monolog.processor.rollbar_context:
        class: AppBundle\Monolog\RollbarContextProcessor
        arguments:  [@security.token_storage]
        tags:
            - { name: monolog.processor, method: processRecord, handler: rollbar }
monolog:
    handlers:
        rollbar:
            type: rollbar
            level: error
            token: %rollbar_token%

Your question has two parts:

Rollbar

person_fn is exactly what you need. You should be able to add a reference to the function by using a string (e.g.: "MyClass::static_function_reference" or "my_function_name").

Symfony

Disclaimer: I don't use or know much about Symfony.

This question has some excellent examples of how to get the current user in Symfony. (Punch line: in a controller you can call $this.getUser())

This question has a good example of how to inject the current user in a service. (Make a Twig Extension that depends on the SecurityContext or TokenStorage, use those dependencies to get a user objet).

Finally, there's the classic PHP move: as soon as you have a user add it to $_REQUEST. I'm not sure if Symfony co-opts this, but it'd be a valid way in a non-framework PHP application.

Thanks for quick answer and inspiration to keep digging. However this was symfony framework specific as you can see in my own answer. — Aurelijus Rozenas, Nov 04 '15 at 20:39
