Try this
stdout := logging.NewLogBackend(os.Stdout, "", 0)
format := logging.MustStringFormatter(`%{color}%{time:15:04:05.000} %{shortfunc} ▶ %{level:.5s} %{id:03x}%{color:reset} %{message}`)
logging.SetFormatter(format)
levelBackend := logging.AddModuleLevel(stdout)
switch strings.ToUpper(*LOG_LEVEL) {
case "CRITICAL":
levelBackend.SetLevel(logging.CRITICAL, "")
case "ERROR":
levelBackend.SetLevel(logging.ERROR, "")
case "WARN":
levelBackend.SetLevel(logging.WARNING, "")
case "NOTICE":
levelBackend.SetLevel(logging.NOTICE, "")
case "DEBUG":
levelBackend.SetLevel(logging.DEBUG, "")
default:
levelBackend.SetLevel(logging.INFO, "")
}
logging.SetBackend(levelBackend)

Yes, you need to pass the constant (logging.DEBUG / logging.INFO) and the name of your logger instance. Only messages written to the logger at the specified allowed level will then be output, others will be discarded.
e.g. use logging.SetLevel(logging.INFO, "myLog")
logger.Info("my message") > is output
logger.debug("my message") !output

Dosent work
logging.SetLevel(logging.INFO,"")
backend := logging.NewLogBackend(os.Stderr, "", 0)
backend2Formatter := logging.NewBackendFormatter(backend, format)
logging.SetLevel(logging.INFO, "myLog")
if strings.ToUpper(*LOG_LEVEL) == "ERROR" {
logging.SetLevel(logging.ERROR, "myLog")
} else if strings.ToUpper(*LOG_LEVEL) == "INFO" {
logging.SetLevel(logging.INFO, log.Module)
} else if strings.ToUpper(*LOG_LEVEL) == "DEBUG" {
logging.SetLevel(logging.DEBUG, "myLog")
} else if strings.ToUpper(*LOG_LEVEL) == "CRITICAL" {
logging.SetLevel(logging.CRITICAL, "myLog")
} else if strings.ToUpper(*LOG_LEVEL) == "NOTICE" {
logging.SetLevel(logging.NOTICE, "myLog")
} else if strings.ToUpper(*LOG_LEVEL) == "WARNING" {
logging.SetLevel(logging.WARNING, "myLog")
} else {
logging.SetLevel(logging.INFO, log.Module)
}
logging.SetBackend(backend2Formatter)
log.Info(logging.GetLevel(log.Module))

@utkudarilmaz Thanx!
from go-logging.
Hi @utkudarilmaz! can i change the log level after the log was initialized? i see that SetLevel() doesn't have any locking mechanism. is this the right way to do it? Logging.SetLevel()? or init the log again?
Thanks.
