The Yeebase.Graylog Flow package logs your exceptions as well as single messages to a central Graylog server. This package also provides a simple backend to log message of Flows Logger classes to a Graylog server.

It depends on the official GELF php package https://github.com/bzikarsky/gelf-php

Just add "yeebase/graylog" as dependency to your composer.json and run a "composer update" in your project's root folder or simply execute:

composer require yeebase/graylog

from your project's root.

Configure your Graylog Server:

Yeebase:
  Graylog:
    host: '127.0.0.1'
    port: 12201
    chunksize: 'wan'

Activate the exception handler and configure the connection to your graylog server in your Settings.yaml:

Neos:
  Flow:
    error:
      exceptionHandler:
        className: 'Yeebase\Graylog\Error\GraylogExceptionHandler'

Note: For Development context, the Neos.Flow package overrides this setting. Make sure to add this configuration in the right context Settings.yaml.

To skip certain exceptions from being logged you can either use the skipStatusCodes setting:

Yeebase:
  Graylog:
     # don't log any exceptions that would result in a HTTP status 403 (access denied) / 404 (not found)
    skipStatusCodes: [403, 404]

Since version 2.1 you can alternatively use the renderingGroups Flow setting, i.e. to exclude certain Exception classes from being logged:

Neos:
  Flow:
    error:
      exceptionHandler:
        className: 'Yeebase\Graylog\Error\GraylogExceptionHandler'
        renderingGroups:
          'accessDeniedExceptions':
            matchingExceptionClassNames: ['Neos\Flow\Security\Exception\AccessDeniedException']
            options:
              logException: false

If you wish to log normal log messages to your Graylog server just use the provided GraylogLoggerInterface:

use Neos\Flow\Annotations as Flow;
use Yeebase\Graylog\Log\GraylogLoggerInterface;

class SomeClass 
{
    /**
     * @Flow\Inject
     * @var GraylogLoggerInterface
     */
    protected $graylogLogger;

    public function yourMethod()
    {
      $this->graylogLogger->log('Your Message')
    }
}
