[Logger] Allow to add processors to monolog

[wodor]

Description

Currently LogFactory just returns one processor (

framework/src/Bridge/Monolog/src/LogFactory.php

Line 132 in cc6cb37

return [new PsrLogMessageProcessor()];

)
I guess the way is to replace it in my application, but it looks like it is not easy to do because it is embedded in MonologBootloader https://github.com/spiral/framework/blob/2.8/src/Bridge/Monolog/src/Bootloader/MonologBootloader.php
So I need to "duplicate" that code too.

Example

It would be great to be able to define processors to add in a bootloader and have the constructor of implementation of LogsInterface that accepts a collection of processors.

Sounds good! Thank you!

[wodor]

I am willing to work on a solution for this, it would be best if I get some direction from the authors.

[butschster]

I think processors could be migrated to MonologConfig like handlers.

Hi @wodor! Could you check PR #506?

We have added the ability to configure channel processors via config:

// config monolog.php

<?php

declare(strict_types=1);

use Monolog\Logger;
use Monolog\Processor\PsrLogMessageProcessor;

return [
    'globalLevel' => Logger::DEBUG,

    'handlers' => [
        'stdout' => [
            [
                'class' => \Monolog\Handler\SyslogHandler::class,
                'options' => [
                    'ident' => 'app',
                    'facility' => LOG_USER,
                ]
            ]
        ],
    ],
    'processors' => [
        'stdout' => [
            [
                'class'   => PsrLogMessageProcessor::class,
                'options' => [
                    'dateFormat' => 'c'
                ]
            ],
        ],
    ]
];
