Overview

The New Relic CLI is a project to consolidate some of the tools that New Relic offers for managing resources. Current scope is limited while the framework is being developed, but the tool as-is does perform a subset of tasks.

• Entity Search: Search for entities across all your New Relic accounts
• Entity Tagging: Manage tags across all of your entities
• Deployment Markers: Easily record an APM Application deployment within New Relic.

Getting Started

For a quick guide on getting started with the New Relic CLI, see our Getting Started page.

New Relic CLI Documentation

The latest New Relic CLI documentation is available in the repository's docs directory.

Installation & Upgrades

Installation options are available for various platforms. If you're running an older version of the CLI you can use these commands to update to the latest version.

MacOS

Automated install

curl -Ls https://download.newrelic.com/install/newrelic-cli/scripts/install.sh | bash

Homebrew

Install the New Relic CLI on MacOS via homebrew. With homebrew installed, run:

brew install newrelic-cli

Windows

Installation is supported on 64-bit Windows.

Automated install

[Net.ServicePointManager]::SecurityProtocol = 'tls12, tls'; (New-Object System.Net.WebClient).DownloadFile("https://download.newrelic.com/install/newrelic-cli/scripts/install.ps1", "$env:TEMP\install.ps1"); & $env:TEMP\install.ps1

Scoop

scoop bucket add newrelic-cli https://github.com/newrelic/newrelic-cli.git
scoop install newrelic-cli

Chocolatey

choco install newrelic-cli

Standalone installer

A standalone MSI installer is available on the New Relic download site. You can download the installer for the latest version here.

Powershell

Silent installation of the latest version of the CLI can be achieved via the follwing Powershell command:

(New-Object System.Net.WebClient).DownloadFile("https://github.com/newrelic/newrelic-cli/releases/latest/download/NewRelicCLIInstaller.msi", "$env:TEMP\NewRelicCLIInstaller.msi"); `
msiexec.exe /qn /i "$env:TEMP\NewRelicCLIInstaller.msi" | Out-Null; `

Linux

Automated install

curl -Ls https://download.newrelic.com/install/newrelic-cli/scripts/install.sh | bash

Snapcraft

Linux binaries can be installed via Snapcraft. With the snapd daemon installed, run:

sudo snap install newrelic-cli

Pre-built binaries

Pre-built binaries are available for all of the above platforms. You can download the latest releases here. The binaries and their checksums are signed and can be verified against the Developer Toolkit team's public PGP key.

Verify that the fingerprint for the downloaded key matches the following:

gpg --fingerprint developer-toolkit@newrelic.com

5961 D131 BB2C 5C6B 42B1  4D0F 92AD A76A 30A3 F1FD

When verifying pre-built binaries and checksums, use the long format (the short format is not secure). For example:

gpg --keyid-format long --verify checksums.txt.sig checksums.txt

Docker

There is an official docker image that can be utilized for running commands as well.

Example Usage

Querying an APM application (using the Docker image)

# Pull the latest container
$ docker pull newrelic/cli

# Run the container interactively, remove it once the command exists
# Also must pass $NEW_RELIC_API_KEY to the container
$ docker run -it --rm \
    -e NEW_RELIC_API_KEY \
    newrelic/cli \
    apm application get --name WebPortal --accountId 2508259

[
  {
    "AccountID": 2508259,
    "ApplicationID": 204261368,
    "Domain": "APM",
    "EntityType": "APM_APPLICATION_ENTITY",
    "GUID": "MjUwODI1OXxBUE18QVBQTElDQVRJT058MjA0MjYxMzY4",
    "Name": "WebPortal",
    "Permalink": "https://one.newrelic.com/redirect/entity/MjUwODI1OXxBUE18QVBQTElDQVRJT058MjA0MjYxMzY4",
    "Reporting": true,
    "Type": "APPLICATION"
  }
]

See the Getting Started guide for a more in-depth introduction to the capabilities of the New Relic CLI.

Getting Help

In order to get help about what commands are available, the trusty --help flag is here to assist. Alternatively, using just the help subcommand also works.

newrelic --help
newrelic help

Help is also available for the nested sub-commands. For example, the with the following command, you can retrieve help for the apm sub-command.

newrelic apm --help
newrelic help apm

Using the CLI in this way, users are able to inspect what commands are available, with some instruction on their usage.

Patterns

Throughout the help, you may notice common patterns. The term describe is used to perform list or get operations, while the create and delete terms are used to construct or destroy an item, respectively.

Development

Requirements

• Go 1.19+
• GNU Make
• git

Building

The newrelic command will be built in bin/ARCH/newrelic, where ARCH is either linux, darwin, or windows, depending on your build environment. You can run it directly from there or install it by moving it to a directory in your PATH.

# Default target is 'build'
$ make

# Explicitly run build
$ make build

# Locally test the CI build scripts
# make build-ci

Testing

Before contributing, all linting and tests must pass. Tests can be run directly via:

# Tests and Linting
$ make test

# Only unit tests
$ make test-unit

# Only integration tests
$ make test-integration

Working with recipes

Core recipe library

A core library of installation recipes is included with the CLI for use within the install command. Recipe files are syndicated from open-install-library and embedded in the CLI binary at release time. To fetch the latest recipe library while developing, the following make target can be used:

make recipes

Recipe files are stored in internal/install/recipes/files. Once files have been fetched, they will be included in future CLI builds. If a particular version of the recipe library is desired, the archive download URL can be passed to the make target via the RECIPES_ARCHIVE_URL option:

make recipes RECIPES_ARCHIVE_URL=https://github.com/newrelic/open-install-library/releases/download/v0.50.0/recipes.zip

To clean recipe files, use the recipes-clean target:

make recipes-clean

Custom recipe files

A path can also be passed to the --localRecipes flag when running the install command. This will bypass the methods described above and load files from the designated path.

Experimenting (internal New Relic usage only)

Using A/B tests, New Relic developers have the ability to gradually roll out new features.

Define an experiment

With access to Split.io, internal New Relic developers can create new A/B tests. Upon creating one, reference the exact name of the experiment in internal/split/constants.go. Make sure this is the exact name of the experiment in Split.io.

Retrieve treatments

You can retrieve the status of the treatment by using the SplitService.

// Retrieve a single treatment given an experiment (split)
treatment := split.SplitService.Get(split.VirtuosoCLITest)

if treatment == "on" {
  // insert code here to show on treatment
} else if treatment == "off" {
  // insert code here to show off treatment
} else {
  // insert your control treatment code here
}

// Retrieve multiple treatments given a list of experiments (splits)
splits := []string{split.VirtuosoCLITest, split.VirtuosoCliTest2}
treatments := split.SplitService.GetAll(splits)
for split, treatment := range treatments {
    fmt.Printf("Treatment for feature %s is %s\n", split, treatment)
    // Evaluate treatments
}

Commit Messages

Using the following format for commit messages allows for auto-generation of the CHANGELOG:

Format:

<type>(<scope>): <subject>

Type	Description	Change log?
chore	Maintenance type work	No
docs	Documentation Updates	Yes
feat	New Features	Yes
fix	Bug Fixes	Yes
refactor	Code Refactoring	No

Scope

This refers to what part of the code is the focus of the work. For example:

General:

• build - Work related to the build system (linting, makefiles, CI/CD, etc)
• release - Work related to cutting a new release

Package Specific:

• newrelic - Work related to the New Relic package
• http - Work related to the internal/http package
• alerts - Work related to the pkg/alerts package

Generating CLI Documentation

Note: This requires the repo to be in your GOPATH (godoc issue)

$ make docs
