What is the syslog in Linux?

Syslog is a protocol and utility for capturing and logging system information. This system information can be stored locally, remotely, or both. syslog allows a server to forward log messages over the network to SL1. SL1 then uses these messages to monitor the health of the server and trigger events (if necessary).

Facility being the type of message, such as a kernel or mail message. And level being a severity level of the message. So to determine the facility value of a syslog message we divide the priority value by 8. The remainder is the level value.
