zslog

zslog

Simply configuring zerolog with output to console, lumberjack.v2, sentry-go

Features

• Easy use
• Error Logging with stacktrace
• Contextual Logging to Payload sentry context
• Set log level for each outputs

Example

package main

import (
    "github.com/mef13/zslog"
    "time"
)

func main() {
    fileConf := zslog.FileConfig{
        MaxSize:    1,
        MaxBackups: 10,
    }
    zslog.InitLogger(
        zslog.StdOut(zslog.NewLevels().SetMaxLevel(zslog.WarnLevel)),
        zslog.StdErr(zslog.NewLevels().SetMinLevel(zslog.ErrorLevel)),
        zslog.File("/var/log/myapp/err.log", fileConf, zslog.NewLevels().SetMinLevel(zslog.ErrorLevel)),
        zslog.Sentry(zslog.SentryConfig{
            Dsn:              "https://public@sentry.example.com/1",
            Release:          "0.0",
        }, 3*time.Second, zslog.NewLevels().SetMinLevel(zslog.ErrorLevel)))

    //Flush sentry buffer before exit
    defer zslog.Close()

    zslog.Info().Msg("hello world")
}

Set log level for output

Set specific levels:

zslog.StdOut(zslog.NewLevels(zslog.ErrorLevel, zslog.WarnLevel))

or set maximum(minimum) level:

zslog.StdOut(zslog.NewLevels().SetMaxLevel(zslog.WarnLevel))

Error Logging with Stacktrace

For add stacktrace use Stack() function:

package main

import (
	"github.com/mef13/zslog"
	"github.com/pkg/errors"
	"time"
)

func main() {
	zslog.InitLogger(
		zslog.Sentry(zslog.SentryConfig{
			Dsn:     "https://public@sentry.example.com/1",
			Release: "0.0",
		}, 3*time.Second, zslog.NewLevels().SetMinLevel(zslog.ErrorLevel)))

	//Flush sentry buffer before exit
	defer zslog.Close()

	err = outer()
	zslog.Error().Stack().Err(err).Msg("outer error")
}

func inner() error {
	return errors.New("Ah s*, here we go again")
}

func middle() error {
	err := inner()
	if err != nil {
		return err
	}
	return nil
}

func outer() error {
	err := middle()
	if err != nil {
		return err
	}
	return nil
}
