Syslog source plugin
Syslog is a standard protocol used for message logging and management in Unix and Unix-like systems. It is widely used for system monitoring, debugging, and troubleshooting.
The Syslog source plugin can collect messages through a Unix socket server using UDP or TCP, or over the network using TCP or UDP. It provides a flexible and customizable way to configure your Calyptia Core pipeline to receive, parse, and process Syslog messages.
Configuration parameters
The Syslog source plugin provides these configuration parameters.

| Port | TCP port used for listening for incoming messages. |
| Parser | Specify an alternative parser for the message. If Mode is set to tcp or udp then the default parser is syslog-rfc5424 otherwise syslog-rfc3164-local is used. If your syslog messages have fractional seconds, set this value to syslog-rfc5424 instead. If you have a custom parser, use Advanced Settings to designate the parser. |
