Overview

Package syslog provides a simple interface to the system log service. It can send messages to the syslog daemon using UNIX domain sockets, UDP or TCP.

Only one call to Dial is necessary. On write failures, the syslog client will attempt to reconnect to the server and write again.

func NewLogger

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.

type Priority

type Priority int

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.

const (

	// From /usr/include/sys/syslog.h.
	// These are the same on Linux, BSD, and OS X.
	LOG_EMERG Priority = iota
	LOG_ALERT
	LOG_CRIT
	LOG_ERR
	LOG_WARNING
	LOG_NOTICE
	LOG_INFO
	LOG_DEBUG
)
const (

	// From /usr/include/sys/syslog.h.
	// These are the same up to LOG_FTP on Linux, BSD, and OS X.
	LOG_KERN Priority = iota << 3
	LOG_USER
	LOG_MAIL
	LOG_DAEMON
	LOG_AUTH
	LOG_SYSLOG
	LOG_LPR
	LOG_NEWS
	LOG_UUCP
	LOG_CRON
	LOG_AUTHPRIV
	LOG_FTP

	LOG_LOCAL0
	LOG_LOCAL1
	LOG_LOCAL2

	LOG_LOCAL4
	LOG_LOCAL5
	LOG_LOCAL6
	LOG_LOCAL7

type Writer

type Writer struct {
	// contains filtered or unexported fields
}

A Writer is a connection to a syslog server.

func Dial

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 network net. Each write to the returned writer sends a log message with the given facility, severity and tag.

func New

func New(priority Priority, tag string) (w *Writer, err 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 (*Writer) Alert

func (w *Writer) Alert(m string) (err error)

Alert logs a message with severity LOG_ALERT, ignoring the severity passed to New.

func (*Writer) Close

func (w *Writer) Close() error

Close closes a connection to the syslog daemon.

func (*Writer) Crit

func (w *Writer) Crit(m string) (err error)

Crit logs a message with severity LOG_CRIT, ignoring the severity passed to New.

func (*Writer) Debug

func (w *Writer) Debug(m string) (err error)

Debug logs a message with severity LOG_DEBUG, ignoring the severity passed to New.

func (*Writer) Emerg

func (w *Writer) Emerg(m string) (err error)

Emerg logs a message with severity LOG_EMERG, ignoring the severity passed to New.

func (*Writer) Err

func (w *Writer) Err(m string) (err error)

Err logs a message with severity LOG_ERR, ignoring the severity passed to New.

func (*Writer) Info

func (w *Writer) Info(m string) (err error)

Info logs a message with severity LOG_INFO, ignoring the severity passed to New.

func (*Writer) Notice

func (w *Writer) Notice(m string) (err error)

Notice logs a message with severity LOG_NOTICE, ignoring the severity passed to New.

func (*Writer) Warning

func (w *Writer) Warning(m string) (err error)

Warning logs a message with severity LOG_WARNING, ignoring the severity passed to New.
