README

go-level-logger

Features

• Dynamically config log level
• Output debug/info/notice messages to stdout, and output warn/error mssages to stdout/stderr
• Customize log output

Examples

Basic

package main

import (
    "github.com/hongjundu/go-level-logger"
)

func main() {
    logger.InitLogger(logger.LogLevelDebug)

    logger.Debugf("debug message")
    logger.Infof("info message")
    logger.Noticef("notice message")
    logger.Warnf("warn message")
    logger.Errorf("error message")
}

Customize log output

package main

import (
    "github.com/hongjundu/go-level-logger"
)

func main() {
    logger.Init(logger.LogLevelDebug, "example", "/tmp", 100, 3, 365)

    logger.Debugf("debug message")
    logger.Infof("info message")
    logger.Noticef("notice message")
    logger.Warnf("warn message")
    logger.Errorf("error message")
}

Customize rotate log output (Rotate log at 00:00:00 per day)

package main

import (
    "github.com/hongjundu/go-level-logger"
)

func main() {
    logger.InitRotateLogger(logger.LogLevelDebug, "example", "/tmp", 100, 3, 365, logger.RotateStrategyPerDay)

    logger.Debugf("debug message")
    logger.Infof("info message")
    logger.Noticef("notice message")
    logger.Warnf("warn message")
    logger.Errorf("error message")
}

Customize rotate log output (Rotate log per hour)

package main

import (
    "github.com/hongjundu/go-level-logger"
)

func main() {
    logger.InitRotateLogger(logger.LogLevelDebug, "example", "/tmp", 100, 3, 365, logger.RotateStrategyPerHour)

    logger.Debugf("debug message")
    logger.Infof("info message")
    logger.Noticef("notice message")
    logger.Warnf("warn message")
    logger.Errorf("error message")
}
