Graylog2 with Symfony 2 (Monolog)

Question

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"

My SF2 config.yml:

monolog:
    handlers:
        main:
            type: gelf
            publisher:
                hostname: %Graylog2.Host%
                port: %Graylog2.Port%
            level: info
            formatter: monolog.formatter.session_request

But now, if I want to log something, I get an error in GelfHandler::write()

Gelf\Publisher::publish() must be an instance of Gelf\MessageInterface, string given

What is wrong here?

Answer 1

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
