Mastering Go - Second Edition

A Go program that sends information to log files

The Go code of logFiles.go will explain the use of the log and log/syslog packages to write to the system log files.

Please note that the log/syslog package is not implemented on the Microsoft Windows version of Go.

The first part of logFiles.go is as follows:

package main 
 
import ( 
    "fmt" 
    "log" 
    "log/syslog" 
    "os" 
    "path/filepath" 
) 
 
func main() { 
    programName := filepath.Base(os.Args[0]) 
    sysLog, err := syslog.New(syslog.LOG_INFO|syslog.LOG_LOCAL7,  programName)

The first parameter to the syslog.New() function is the priority, which is a combination of the logging facility and the logging level. Therefore, a priority of LOG_NOTICE | LOG_MAIL, which is mentioned as an example, will send notice logging ...
