syslog is the default logging daemon on Linux. The default syslog configuration file is the/etc/syslog.conf file. Programs, daemons, and kernels provide logging information for accessing the system. Therefore, any program that wishes to generate log information can call the syslog interface to generate that information.

Almost all network devices can transmit log information to remote servers in the form of User Datagram Protocol (UDP) through syslog protocol. Remote log receiving servers must listen to UDP port 514 through syd, and process the local machine according to the configuration in syslog.conf configuration file, receive log information from accessing the system, and write specified events to specific files for background database management and response. This means that any event can be logged on to one or more servers for the backend database to analyze events on remote devices off-line.

Typically, syslog accepts messages from various functions of the system, each message including a level of importance./ The/etc/syslog.conf file tells syd how to report information based on device and message importance levels.
