import "log/syslog"
syslog 包提供一个简单的系统日志服务的接口。 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.
The syslog package is frozen and is not accepting new features. Some external packages provide more functionality. See:
https://godoc.org/?q=syslog
doc.go syslog.go syslog_unix.go
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.
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_LOCAL3 LOG_LOCAL4 LOG_LOCAL5 LOG_LOCAL6 LOG_LOCAL7 )
type Writer struct {
// contains filtered or unexported fields
}
A Writer is a connection to a syslog server.
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.
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.
Alert logs a message with severity LOG_ALERT, ignoring the severity passed to New.
Close closes a connection to the syslog daemon.
Crit logs a message with severity LOG_CRIT, ignoring the severity passed to New.
Debug logs a message with severity LOG_DEBUG, ignoring the severity passed to New.
Emerg logs a message with severity LOG_EMERG, ignoring the severity passed to New.
Err logs a message with severity LOG_ERR, ignoring the severity passed to New.
Info logs a message with severity LOG_INFO, ignoring the severity passed to New.
Notice logs a message with severity LOG_NOTICE, ignoring the severity passed to New.
Warning logs a message with severity LOG_WARNING, ignoring the severity passed to New.
Write sends a log message to the syslog daemon.
☞ This package is not implemented on Windows. As the syslog package is frozen, Windows users are encouraged to use a package outside of the standard library. For background, see https://github.com/golang/go/blob/master/issue/1108.
