Golang SDK for New Relic integrations

Infrastructure monitoring provided by New Relic offers flexible, dynamic server monitoring, including integrations for many popular services.

If our on-host integrations don't meet your needs, we provide two options for creating your own:

  • Our Flex integration tool: a simple way to report custom metrics by creating a configuration file that defines what data will be reported. This is recommended for most use cases.
  • Our Integrations SDK: a more robust solution. We give you access to the complete set of tools we use to build our integrations and report all infrastructure integrations data types.

The Integrations SDK helps take the complexity out of building an integration by providing a set of useful Go language functions and data structures. For instance, some common use cases like reading values from command-line arguments or environment variables, initializing a structure with all the necessary fields for an integration defined by our SDK, or generating and printing a JSON to stdout, are covered and simplified by this package.

If you want to know more or you need specific documentation about the structures and functions provided by this package, you can take a look at the official package documentation in (see below).


Before starting to write Go code, we suggest taking a look at golang's documentation to set up the environment and familiarize yourself with the golang language.

You can download the SDK code to your GOPATH with the following command:

$ go get

Read the SDK documentation to learn about all the packages and functions it provides. If you need ideas or inspiration to start writing integrations, follow the tutorial.

API specification

You can find the latest API documentation generated from the source code in godoc.

Agent API

Infrastructure on-host integrations are executed periodically by the infrastructure agent. The integration stdout is consumed by the agent. stdout data is formatted as JSON.

The agent supports different JSON data-structures called integration protocols:

  • v1: Legacy data structure to monitor local entity.
  • v2: This version allows to monitor remote entities and keep support for previous local entity. Official doc
  • v3: Improves remote entities support. See protocol v3 documentation.
Local vs remote entities

Entity is a specific thing we collect data about. We used this vague term because we want to support hosts, pods, load balancers, DBs, etc. in a generic way. In the previous SDK versions (v1 & v2) the entity was local and just one: the host.

In later versions the reporting host is called local entity, and it's optional to add metrics to it. You could just use remote entities to attach metrics.

For more information on the definition of a remote entity, please see the following document on local vs remote entites.

Upgrading from SDK v2 to v3

SDK and agent-protocol compatibility

SDK v1 and v2 use protocol-v1.

SDK v3 could use either protocol-v2 or protocol-v3.


This section shows the documentation of all the core components of the GoSDK v3, that is, all the packages that are required to set up and manage the integration data, as well as some other libraries that, despite not being part of the core SDK, implement common operations that may be reused in different integrations.

JMX support

The Integrations Golang SDK supports getting metrics through JMX by calling the jmx.Open(), jmx.OpenWithSSL, jmx.Query(), and jmx.Close() functions. This JMX support relies on the nrjmx tool. Follow the steps in the nrjmx repository to build it and set the NR_JMX_TOOL environment variable to point to the location of the nrjmx executable. If the NR_JMX_TOOL variable is not set, the SDK uses /usr/bin/nrjmx by default.

HTTP support

GoSDK v3 provides a helper HTTP package to create secure HTTPS clients that require loading credentials from a Certificate Authority Bundle (stored in a file or in a directory).You can read more here.


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