func NewLogger(p Priority, logFlag int) (*log.Logger, error)
NewLogger creates a log.Logger whose output is written to the system log service with the specified priority, a combination of the syslog facility and severity. The logFlag argument is the flag set passed through to log.New to create the Logger.
The Priority is a combination of the syslog facility and severity. For example, LOG_ALERT | LOG_FTP sends an alert severity message from the FTP facility. The default severity is LOG_EMERG; the default facility is LOG_KERN.

// From /usr/include/sys/syslog.h.

A Writer is a connection to a syslog server.
type Writer struct {
// contains filtered or unexported fields
}
func Dial(network, raddr string, priority Priority, tag string) (*Writer, error)
Dial establishes a connection to a log daemon by connecting to address raddr on the specified network. Each write to the returned writer sends a log message with the facility and severity (from priority) and tag. If tag is empty, the os.Args[0] is used. If network is empty, Dial will connect to the local syslog server. Otherwise, see the documentation for net.Dial for valid values of network and raddr.
▹ Example
func New(priority Priority, tag string) (*Writer, error)
New establishes a new connection to the system log daemon. Each write to the returned writer sends a log message with the given priority (a combination of the syslog facility and severity) and prefix tag. If tag is empty, the os.Args[0] is used.
