loggerTracer is a logger tracing

For Internal use in PoC

loggerTracer wrap arround zap and opentelemetry

Installation

go get -u github.com/dyammarcano/loggerTracer

Note that zap only supports the two most recent minor versions of Go.

Quick Start

In contexts where performance is nice, but not critical, use the SugaredLogger. It's 4-10x faster than other structured logging packages and includes both structured and printf-style APIs.

package main

import (
	"fmt"
	"github.com/dyammarcano/loggerTracer"
	"time"
)

func main() {
	cfg := &loggerTracer.Config{
		LogDir:      "/var/log/app",
		ServiceName: "testService",
	}

	if err := loggerTracer.NewLogger(cfg); err != nil {
		panic(err)
	}

	for i := 0; i < 10; i++ {
		mainFunc(i)
	}
}

func mainFunc(num int) {
	tracer := loggerTracer.NewTracer(fmt.Sprintf("lap %d", num))
	defer tracer.End()

	tracer.Info(fmt.Sprintf("Function Info %d", num), loggerTracer.AddField("key 1", "value 1"))
	innerFunc1(tracer, num)
	innerFunc2(tracer, num)
	innerFunc3(tracer, num)

	tracer.Error(fmt.Sprintf("Function Error %d", num), loggerTracer.AddFieldError(fmt.Errorf("error %d", num)))

	<-time.After(1 * time.Second)
}

func innerFunc1(tracer *loggerTracer.Trace4U, num int) {
	tracer.Info(fmt.Sprintf("Inner Function %d", num), loggerTracer.Entry{Key: "funcKey 1", String: "funcValue 1"})
}

func innerFunc2(tracer *loggerTracer.Trace4U, num int) {
	tracer.Info(fmt.Sprintf("Inner Function %d", num), loggerTracer.Entry{Key: "funcKey 2", String: "funcValue 2"})
}

func innerFunc3(tracer *loggerTracer.Trace4U, num int) {
	tracer.Warn(fmt.Sprintf("Inner Function %d", num), loggerTracer.Entry{Key: "funcKey 3", String: "funcValue 3"})
}
