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

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")

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

Other custom logging options can be set by passing zap configurations to the logger constructor, and passing the custom logger to the apm constructor, like so:

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

var myZapConfig *zap.Config // initialized elsewhere

logger := logger.NewLogger(
    WithConfig(myZapConfig)
)
return apm.NewApm(
    WithLogger(&logger)
)

To use the Serverless Datadog agent, build the application based on the following Dockerfile.

FROM    alpine:3.20
ARG     ARG_VERSION=dev
    
ENV     DD_VERSION=${ARG_VERSION}
ENV     DD_SITE=datadoghq.eu
    
COPY --from=datadog/serverless-init:1.2.8-alpine /datadog-init /datadog/datadog-init
COPY --from=builder /go/bin/main /go/bin/main
