New Relic Go Agent GoDoc Go Report Card

The New Relic Go Agent allows you to monitor your Go applications with New Relic. It helps you track transactions, outbound requests, database calls, and other parts of your Go application's behavior and provides a running overview of garbage collection, goroutine activity, and memory use.

Go is a compiled language, and doesn’t use a virtual machine. This means that setting up New Relic for your Golang app requires you to use our Go agent API and manually add New Relic methods to your source code. Our API provides exceptional flexibility and control over what gets instrumented.

Installation

Compatibility and Requirements

For the latest version of the agent, Go 1.7+ is required, due to the use of context.Context.

Linux, OS X, and Windows (Vista, Server 2008 and later) are supported.

Installing and using the Go agent

To install the agent, follow the instructions in our GETTING_STARTED document or our GUIDE.

We recommend instrumenting your Go code to get the maximum benefits from the New Relic Go agent. But we make it easy to get great data in couple of ways:

  • Even without adding instrumentation, just importing the agent and creating an application will provide useful runtime information about your number of goroutines, garbage collection statistics, and memory and CPU usage.
  • You can use our many INTEGRATION packages for out-of-the box support for many popular Go web frameworks and libraries. We continue to add integration packages based on your feedback. You can weigh in on potential integrations by opening an Issue here in our New Relic Go agent GitHub project.

Upgrading

If you have already been using version 2.X of the agent and are upgrading to version 3.0, see our MIGRATION guide for details.

Getting Started

v3/examples/server/main.go is an example that will appear as "Example App" in your New Relic applications list. To run it:

env NEW_RELIC_LICENSE_KEY=__YOUR_NEW_RELIC_LICENSE_KEY__LICENSE__ \
    go run v3/examples/server/main.go

Some endpoints exposed are http://localhost:8000/ and http://localhost:8000/notice_error

Usage

Integration Packages

The following integration packages extend the base newrelic package to support the following frameworks and libraries. Frameworks and databases which don't have an integration package may still be instrumented using the newrelic package primitives.

Service Frameworks

Project Integration Package
gin-gonic/gin v3/integrations/nrgin Instrument inbound requests through the Gin framework
gorilla/mux v3/integrations/nrgorilla Instrument inbound requests through the Gorilla framework
google.golang.org/grpc v3/integrations/nrgrpc Instrument gRPC servers and clients
labstack/echo v3/integrations/nrecho-v3 Instrument inbound requests through version 3 of the Echo framework
labstack/echo v3/integrations/nrecho-v4 Instrument inbound requests through version 4 of the Echo framework

These integration packages must be imported along with the newrelic package, as shown in this nrgin example.

Alternatives

If you are already using another open source solution to gather telemetry data, you may find it easier to use one of our open source exporters to send this data to New Relic:

Support

Should you need assistance with New Relic products, you are in good hands with several support channels.

If the issue has been confirmed as a bug or is a Feature request, please file a Github issue.

Privacy
