Syslog
Configuring Debug Logging determines where the debug logs are to be displayed, that is,
either on the console or on a file.
Syslog is a protocol used for capturing log information for devices on a network. The syslog
protocol provides a transport to allow a machine to send event notification messages across IP
networks to event message collectors, also known as syslog servers. The protocol is simply
designed to transport the event messages.
One of the fundamental tenets of the syslog protocol and process is its simplicity. The
transmission of syslog messages may be started on a device without a receiver being
configured, or even actually physically present.
This simplicity has greatly aided the acceptance and deployment of syslog.
User enables syslog server and configures the syslog related parameters. The logging process
controls the distribution of logging messages to the various destinations, such as the logging
buffer, logging file, or syslog server.
The existing syslog buffers will not be cleared and none of the configured options will be
changed, when the syslog feature is disabled.
Severity of logging can be set with its numeric value <0-7> or its name tag.
When configuring a server, it should be set with priority tag, reflecting the level of the
message and the facility.

Syslog Priority indicator
The Priority indicator is calculated as:
Priority = 8x facility_coeff severity_level.
