Install New Relic for Go

Our Go agent auto-instruments your code so you can start monitoring your Go language apps and microservices. You can use our launcher, or follow the instructions in this document to complete a basic Go agent installation.

If you don't have one already, create a New Relic account. It's free, forever.

Compatibility and requirements

The Go agent requires Golang 1.17 or higher on Linux, macOS, or Windows. For more information, see Go agent compatibility and requirements.

Install the Go agent

In order to install the Go agent, you need a chave de licença. Then, to install the agent:

   bash

   Copiar

   $
   go get github.com/newrelic/go-agent/v3/newrelic

2. Import the github.com/newrelic/go-agent/v3/newrelic package in your application.

   import "github.com/newrelic/go-agent/v3/newrelic"

   Copiar

3. Initialize the Go agent by adding the following in the main function or in an init block:

   app, err := newrelic.NewApplication(
       newrelic.ConfigAppName("Your Application Name"),
       newrelic.ConfigLicense("YOUR_NEW_RELIC_LICENSE_KEY")
   )

   Copiar

4. Instrument web transactions by wrapping standard HTTP requests in your app code. For example:

   http.HandleFunc(newrelic.WrapHandleFunc(app, "/users", usersHandler))

   Copiar
