Monitor Zap Logs in Go Applications with Atatus Go Agent

Installation steps

Install Atatus Go Agent and logging module

copy
```
go get go.atatus.com/agent
go get go.atatus.com/agent/module/atzap
```

Set up tracer and configure log exporter

copy

import (
    "go.atatus.com/agent"
    "go.atatus.com/agent/module/atzap"

    "go.uber.org/zap"
)
// atzap.Core.WrapCore will wrap the core created by zap.NewExample
// such that logs are also sent to the atzap.Core.
//
// atzap.Core will send "error", "panic", and "fatal" level log
// messages to Atatus APM.

var logger = zap.NewExample(zap.WrapCore((&atzap.Core{}).WrapCore))

func handleRequest(w http.ResponseWriter, req *http.Request) {
    // atzap.TraceContext extracts the transaction and span (if any)
    // from the given context, and returns zap.Fields containing the
    // trace, transaction, and span IDs.
    traceContextFields := atzap.TraceContext(req.Context())
    logger.With(traceContextFields...).Debug("handling request")

    // Output:
    // {"level":"debug","msg":"handling request","trace.id":"67829ae467e896fb2b87ec2de50f6c0e","transaction.id":"67829ae467e896fb"}
