How to Configure Monolog to Exclude 404 Errors from the Log
How to Configure Monolog to Exclude 404 Errors from the Log¶
Sometimes your logs become flooded with unwanted 404 HTTP errors, for example,
when an attacker scans your app for some well-known application paths (e.g.
/phpmyadmin). When using a fingers_crossed
handler, you can exclude
logging these 404 errors based on a regular expression in the MonologBundle
configuration:
- YAML
1 2 3 4 5 6 7 8 9
# app/config/config.yml monolog: handlers: main: # ... type: fingers_crossed handler: ... excluded_404s: - ^/phpmyadmin
- XML
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
<!-- app/config/config.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" xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd http://symfony.com/schema/dic/monolog http://symfony.com/schema/dic/monolog/monolog-1.0.xsd"> <monolog:config> <monolog:handler type="fingers_crossed" name="main" handler="..."> <!-- ... --> <monolog:excluded-404>^/phpmyadmin</monolog:excluded-404> </monolog:handler> </monolog:config> </container>
- PHP
1 2 3 4 5 6 7 8 9 10 11 12 13
// app/config/config.php $container->loadFromExtension('monolog', array( 'handlers' => array( 'main' => array( // ... 'type' => 'fingers_crossed', 'handler' => ..., 'excluded_404s' => array( '^/phpmyadmin', ), ), ), ));
