Add a processor to monolog to append dynamic extra fields.

Installation

Composer.json

"wakeonweb/gelf-extra-logger-bundle": "^1.0",

config/bundles.php

    Wakeonweb\GelfExtraLogger\WakeonwebGelfExtraLoggerBundle::class => ['all' => true],

Configuration

config/packages/wakeonweb_gelf_extra_logger.yaml

wakeonweb_gelf_extra_logger:
    extra_fields:
        my_extra_field: '%env(resolve:MY_EXTRA_ENV_VAR)%'
        my_other_field: 'foo'

Then configure your monolog to use gelf handler:

#This is an example, use fingers_crossed in prod enviroment !
monolog:
    handlers:
        gelf:
            type: gelf
            publisher:
                hostname: "..."
                port: "..."
            level: debug

It'll add my_extra_field and my_other_field at the root of the record in gelf destination.
