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.

Compatibility and Requirements

For the latest version of the agent, Go 1.7+ is required, due to the use of context.Context. (For versions 2.X and earlier of the Go agent, Go 1.3+ is required.)

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.

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
julienschmidt/httprouter v3/integrations/nrhttprouter Instrument inbound requests through the HttpRouter framework
micro/go-micro v3/integrations/nrmicro Instrument servers, clients, publishers, and subscribers through the Micro framework

Datastores

More information about instrumenting databases without an integration package using newrelic package primitives can be found here.

Project Integration Package
lib/pq v3/integrations/nrpq Instrument PostgreSQL driver
go-sql-driver/mysql v3/integrations/nrmysql Instrument MySQL driver
elastic/go-elasticsearch v3/integrations/nrelasticsearch-v7 Instrument Elasticsearch datastore calls
database/sql Use a supported database driver or builtin instrumentation Instrument database calls with SQL
jmoiron/sqlx Use a supported database driver or builtin instrumentation Instrument database calls with SQLx
go-redis/redis v3/integrations/nrredis-v7 Instrument Redis calls
mattn/go-sqlite3 v3/integrations/nrsqlite3 Instrument SQLite driver
snowflakedb/gosnowflake v3/integrations/nrsnowflake Instrument Snowflake driver
mongodb/mongo-go-driver v3/integrations/nrmongo Instrument MongoDB calls

Logging

Project Integration Package
sirupsen/logrus v3/integrations/nrlogrus Send agent log messages to Logrus
mgutz/logxi v3/integrations/nrlogxi Send agent log messages to Logxi
uber-go/zap v3/integrations/nrzap Send agent log messages to Zap

AWS

Project Integration Package
aws/aws-sdk-go v3/integrations/nrawssdk-v1 Instrument outbound calls made using Go AWS SDK
aws/aws-sdk-go-v2 v3/integrations/nrawssdk-v2 Instrument outbound calls made using Go AWS SDK v2
aws/aws-lambda-go v3/integrations/nrlambda Instrument AWS Lambda applications

GraphQL

Project Integration Package
graph-gophers/graphql-go v3/integrations/nrgraphgophers Instrument inbound requests using graph-gophers/graphql-go
graphql-go/graphql v3/integrations/nrgraphqlgo Instrument inbound requests using graphql-go/graphql

Misc

Project Integration Package
pkg/errors v3/integrations/nrpkgerrors Wrap pkg/errors errors to improve stack traces and error class information
openzipkin/b3-propagation v3/integrations/nrb3 Add B3 headers to outgoing requests
nats-io/nats.go v3/integrations/nrnats Instrument publishers and subscribers using the NATS client
nats-io/stan.go v3/integrations/nrstan Instrument publishers and subscribers using the NATS streaming client

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

Runnable Example

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

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

At New Relic we take your privacy and the security of your information seriously, and are committed to protecting your information. We must emphasize the importance of not sharing personal data in public forums, and ask all users to scrub logs and diagnostic information for sensitive information, whether personal, proprietary, or otherwise.

We define "Personal Data" as any information relating to an identified or identifiable individual, including, for example, your name, phone number, post code or zip code, Device ID, IP address and email address.

Please review New Relic’s General Data Privacy Notice for more information.

Contributing

We encourage your contributions to improve the Go Agent! Keep in mind when you submit your pull request, you'll need to sign the CLA via the click-through using CLA-Assistant. You only have to sign the CLA one time per project. If you have any questions, or to execute our corporate CLA, required if your contribution is on behalf of a company, please drop us an email at opensource@newrelic.com.

A note about vulnerabilities

As noted in our security policy, New Relic is committed to the privacy and security of our customers and their data. We believe that providing coordinated disclosure by security researchers and engaging with the security community are important means to achieve our security goals.
