[syslog-ng] Syslog-NG RFC

Hi all, I have configure the Syslog-NG with MongoDB and LogAnalyzer, and as output i have the messages but i have no Date, Facility Severity Syslogtag and other information from it. If i go on a message itself i have some additional information. I have found out that i should use some RFC model 5424. Is there an option to configure the syslog-ng to send this messages in that RFC format ? Kind regards Ivan
