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. 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.

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 given facility, severity and tag. 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 and prefix.
func (w *Writer) Alert(m string) error
Alert logs a message with severity LOG_ALERT, ignoring the severity passed to New.
func (w *Writer) Close() error
Close closes a connection to the syslog daemon.
func (w *Writer) Crit(m string) error
Crit logs a message with severity LOG_CRIT, ignoring the severity passed to New.
func (w *Writer) Debug(m string) error
Debug logs a message with severity LOG_DEBUG, ignoring the severity passed to New.
func (w *Writer) Emerg(m string) error
