.. index:: RFC 3164 RFC 3164 ======== RFC 3164 is a `IETF `_ document. It describes how `syslog `_ messages have been seen in traditional implementations. RFC 3164 is not a standard but rather a descriptive ("informational" in IETF terms) document. It does not demand a specific behaviour but rather documents what has been seen. Some existing implementations of real-world syslog use different formats. RFC 3164 is just the first step towards a newer and better syslog standard. A standard already produced by this working group is :doc:`RFC 3195 <../glossaryofterms/rfc3195>`, which describes how syslog can be sent reliably over a :doc:`TCP <../glossaryofterms/tcp>` connection. Adiscon supports RFC 3164 messages. There are a number of switches in each product to take care of those implementation that do it slightly different. The formal specification for RFC 3164 can be found in the `IETF RFC `_ repository.
