Overview
Package log implements a small wrapper around the std lib log package. It implements log levels by prefixing the logs with [INFO], [DEBUG], [WARNING] or [ERROR]. All output goes to standard error. It is expected the logging flows into journald; journald adds its own timestamp. So timestamping logs is disabled here.
Examples:
log.Info("this is some logging"), will log on the Info level.
log.Debug("this is debug output"), will log in the Debug level, etc.

Variables
var D = &d{}
D controls whether we should output debug logs. If true, we do. Once set it can be unset with Clear.
func Debug
func Debug(v ...interface{})
Debug is equivalent to log.Print(), but prefixed with “[DEBUG] “. It only outputs something if D is true.
func Debugf
func Debugf(format string, v ...interface{})
Debugf is equivalent to log.Printf(), but prefixed with “[DEBUG] “. It only outputs something if D is true.
func Discard
func Discard()
Discard sets the log output to /dev/null.
func Error
func Error(v ...interface{})
Error is equivalent to log.Print, but prefixed with “[ERROR] “.
func Errorf
func Errorf(format string, v ...interface{})
Errorf is equivalent to log.Printf, but prefixed with “[ERROR] “.
func Fatal
func Fatal(v ...interface{})
Fatal is equivalent to log.Print, but prefixed with “[FATAL] “, and calling os.Exit(1).
func Fatalf
func Fatalf(format string, v ...interface{})
Fatalf is equivalent to log.Printf, but prefixed with “[FATAL] “, and calling os.Exit(1)
func Info
func Info(v ...interface{})
Info is equivalent to log.Print, but prefixed with “[INFO] “.
func Infof
func Infof(format string, v ...interface{})
Infof is equivalent to log.Printf, but prefixed with “[INFO] “.
func SetSuffix
func SetSuffix(s string)
SetSuffix set a possible suffix string that is printed after the log level. An extra space is added to this string. Use the empty string to clear.
func Warning
func Warning(v ...interface{})
Warning is equivalent to log.Print, but prefixed with “[WARNING] “.
func Warningf
func Warningf(format string, v ...interface{})
Warningf is equivalent to log.Printf, but prefixed with “[WARNING] “.
