How to Configure Monolog to Exclude Specific HTTP Codes from the Log

Sometimes your logs become flooded with unwanted HTTP errors, for example, 403s and 404s. When using a fingers_crossed handler, you can exclude logging these HTTP codes based on the MonologBundle configuration:

# config/packages/prod/monolog.yaml
monolog:
    handlers:
        main:
            # ...
            type: fingers_crossed
            handler: ...
            excluded_http_codes: [403, 404, { 400: ['^/foo', '^/bar'] }]

<!-- config/packages/prod/monolog.xml -->
<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:monolog="http://symfony.com/schema/dic/monolog"

    <monolog:config>
        <monolog:handler type="fingers_crossed" name="main" handler="...">
            <!-- ... -->
            <monolog:excluded-http-code code="403">
                <monolog:url>^/foo</monolog:url>
                <monolog:url>^/bar</monolog:url>
            </monolog:excluded-http-code>
            <monolog:excluded-http-code code="404" />
        </monolog:handler>
    </monolog:config>
</container>

// config/packages/prod/monolog.php
$container->loadFromExtension('monolog', array(
    'handlers' => array(
        'main' => array(
            // ...
            'type'                => 'fingers_crossed',
            'handler'             => ...,
            'excluded_http_codes' => array(403, 404),
        ),
    ),
