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.


PortTCP port used for listening for incoming messages.
ParserSpecify 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.
ModeSpecify UDP or TCP.
