Monolog and/or PSR-3

@aktau Thanks spotting it. following standard is a good way. I'll check it in this weekend.

@chobie Thanks! It would be nice if you could investigate. Monolog is definitely one of the most used logging frameworks in the (modern) PHP world, and it already implements PSR-3. Usually I'm not a fan for too much standardization because it can grow mediocre solutions, but in the world of logging I think standardizations is absolutely a good thing. It means being able to swap backends easily, which is all I really care about with logging.

I saw PSR-3 logger interface documentation. PSR-3 logger uses RFC 5424 log levels but usually we don't use that levels with fluentd.

let's assume the use case like this.

story: logging user error which user does not have right permission.

usage:
$psr3_fluent_logger->emergency("user", array("user_id" => 12345, "error_code" => ($permission_denied = 1));

output:
2013-05-28 emergency.user {user_id: 12345, error_code: 1}

Admitting that use case makes sense with fluentd. but it dose not make sense with other logger I think.
We can provide PSR-3 logger interface but I don't think this is good way.
Developers are able to switch log backends if we provide PSR-3 logger. but I don't think they want to collect messy logs.

Currently, there are several semistructured log collector: fluentd, scribed, flume...etc.
Those users have some objective to analyze corrected log data.
Not to put too fine a point on it. syslog style log message is just put log data. there is nothing more or less.

Anyway, I do not provide PSR-3 style logger at this time. I'll work when fig accepted PSR-N semistructured logger.
