# Syslog Settings Syslog is a standard protocol used for message logging. It allows devices and applications to generate logs, which are messages about events that have occurred. These logs can contain information about system errors, warnings, informational messages, and more.
## Settings ### Server Address The address of the syslog server. IP address, server name, FQDN etc. formats can be entered. It is mandatory to fill in this field. ### TLS / Port Number / Protocol TLS is used to determine whether the secure channel will be used in syslog transactions. Although it is a port-independent setting but port information may change depending on the selection made here. The port that the syslog server listens to in order to send messages. By default, most syslog servers use UDP port 514. Secure channel and TCP port information may need to be obtained from the syslog server administrator. ### **RFC 3164** This document defines the classic Unix syslog protocol and message format. It describes the traditional syslog format used primarily in BSD systems. While still in use in many systems, it lacks structured data and some security aspects. ### **RFC 5424** Bu RFC, daha modern bir yaklaşım sunar ve genişletilmiş syslog protokolünü tanımlar. RFC 5424, geleneksel syslog formatının sınırlamalarını aşmak için yapılandırılmış veri eklemeyi ve daha geniş bir mesaj formatını desteklemeyi amaçlar. Bu sayede, daha karmaşık ve ayrıntılı bilgi aktarımına olanak tanır ve güvenlik özelliklerini içerir. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
