Symfony version	2.8.15

Symfony 2.8.15 always shows an empty logger on the debug toolbar (and I know there are some deprecations on my code). I tried to update to Symfony 3.2.0 and it shows the logs.

I tried to find a lower version where it works but it was imposible for 2.8 atleast.

My config_dev.php:

imports:
    - { resource: config.yml }

framework:
    router:
        resource: %kernel.root_dir%/config/routing_dev.yml
        strict_requirements: true
    profiler:
        only_exceptions: false

web_profiler:
    toolbar: true
    intercept_redirects: false

monolog:
    handlers:
        main:
            type: stream
            path: %kernel.logs_dir%/%kernel.environment%.log
            level: debug
            channels: [!event]
        console:
            type: console
            channels: [!event, !doctrine]

Fixed using symfony/monolog-bundle prior to 3.0.1. Still dont get why it works on sf3.2.0. Is there a fix that can be backported to 2.8.x?

@jordisala1991 Which version combinations of Symfony and MonologBundle do not work?

[jordisala1991]

MonologBundle: 3.0.1
Symfony: 2.8.15

The DebugHandler currently is indeed not usable with MonologBundle 3.x and any version of the FrameworkBundle before 3.2 (see symfony/monolog-bundle#184 (comment) and symfony/monolog-bundle#188 (comment)).

However, the latest 2.x release of MonologBundle suffers from a similar issue which at least should be resolved by #21061 and symfony/monolog-bundle#195.

This seems to be broken from Symfony >= 2.8.14, even when using monolog-bundle 2.x.

I created 3 complete new checkouts of Symfony standard, 2.8.13 - 2.8.15.
On 2.8.13, the logs shows in the Symfony profiler.
From 2.8.14 onwards, no logs shows, and both 2.8.14 and 2.8.15 uses monolog-bundle 2.11.3
