Golang Datadog APM package with traces and a connected logger

Description

This package makes it possible to add Datadog spans to your code and connect logs to your traces inside datadog based on the following parts:

• Datadog tracer
• Zap logger

Usage

go get github.com/YourSurpriseCom/go-datadog-apm

import(
    github.com/YourSurpriseCom/go-datadog-apm/apm
)

apm := apm.NewApm()
currentContext := context.Background()

//Start a span
span, spanContext := apm.StartSpanFromContext(currentContext, "GetSignedUrl")
defer span.Finish()

//Create debug log message
apm.Logger.Debug(spanContext, "This log message will be linked to the span based on the spanContext")

Configuration

The log level can be configure by setting the environment variable LOG_LEVEL with the following values:

• debug
• info
• warning
• fatal

When not set, it will fall back to the value info
