MonologBundle processor per handler

[flip111]

Problem description:
The configuration option for processors per handler is not available.

Docs: http://symfony.com/doc/current/cookbook/logging/monolog.html#adding-a-session-request-token

If you use several handlers, you can also register the processor at the handler level instead of globally.

Example: https://github.com/symfony/MonologBundle/blob/master/DependencyInjection/Configuration.php#L562

Error:

[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]
Unrecognized options "processors" under "monolog.handlers.main"

Config:

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
            processors: [@monolog.processor.log]

Notice that no actual configuration option for "processors" can be found in the DI configuration.

Note: this is a copy of symfony/symfony#10704

This is outdated doc. Processors are registered by tagging them as monolog.processor, not by giving their id in the config

I hope I described the issue properly: symfony/symfony-docs#3798

@stof how can the processor be registered now to a specific handler? And maybe also nice to know: how can they be registered globally?

Also note that it's not just the symfony documentation by also the MonologBundle gives a wrong example.

the tag can has either a handler attribute to register it for a specific handler only, or a channel attribute for a specific channel
