I want to use the \"Monolog -> GelfHandler\" in a SF2 project. So I\'ve added the following to my composer.json:
\"graylog2/gelf-php\": \"dev-master\"
ok, i will answer my question by my self. the failure is to change the "formatter" or you have to use a formatter is sub-classes from Monolog\Formatter\GelfMessageFormatter.
thx @ all
