New Relic infrastructure agent

The infrastructure agent (infra-agent) collects inventory data and metrics of your hosts and sends it to the New Relic platform.

New Relic's infrastructure monitoring provides flexible, dynamic monitoring of your entire infrastructure, from services running in the cloud or on dedicated hosts to containers running in orchestrated environments.

Compatibility and requirements

Go 1.11 or higher is required to build the infrastructure agent.

You can build the agent for any OS and architecture supported by Go; New Relic does not provide support for all of them. For more information on operating systems supported by New Relic, see the agent compatibility docs.

Set up your license key

Before using the agent, you need to add the New Relic license key to the newrelic-infra.yml configuration file. The default location is:

• Linux: /etc/newrelic-infra.yml
• Windows: C:\Program Files\New Relic\newrelic-infra\newrelic-infra.yml

For more information on configuration methods, precedence, and structure, see the Configure the Infrastructure agent document.

Compile and build the agent

This repository contains a number of scripts that facilitate building infra-agent for environments supported by New Relic: Linux, Windows, and Docker.

To build the agent for architectures and OSes different than the one where the build is running, set the Go environment variables to target the desired OS/Architecture combination. For example:

$ make dist-for-os GOOS=linux

To compile and build the agent run these commands:

• Linux:

  $ make compile # On CentOS 5: make compile-centos-5
  $ make dist
  

• Windows:

  PS C:\> ./win_build.ps1
  

• Docker: see the instructions for building a Docker image.

To build the agent on CentOS 5 use Go 1.9

Run the agent

Once you've built the agent, you'll find the following binary files inside the target/bin/{OS_ARCH} directory:

• newrelic-infra: Main process of the agent, tasked with gathering host data and running integrations.
• newrelic-infra-service: Parent process that looks after the main process, making sure it executes and stays up.
• newrelic-infra-ctl: Troubleshooting utility that enables verbose logs and executes health checks. For more information, see Troubleshooting a running agent.

The agent could run in root/privileged/unprivileged/administrator(win) mode.

Use the agent

You can start, stop, restart, and check the Infrastructure agent from the command line.

For more information, see our official documentation.

Testing

To execute unit tests, run this command:

$ make test

You can run a specific test by invoking go (which is also how you can run tests on Windows):

$ go test -race -run ''      # Run all tests.
$ go test -race -run Foo     # Run top-level tests matching "Foo", such as "TestFooBar".
$ go test -race -run Foo/A=  # For top-level tests matching "Foo", run subtests matching "A=".
$ go test -race -run /A=1    # For all top-level tests, run subtests matching "A=1".

For more information, see Testing in the official Go docs.

Automated tests

Packaging and harvest tests can be run in an automated way using ansible.

Packaging tests

Harvest tests

In order to spin ec2 instances and run these tests automated tests ansible project can be used.

Automated tests

You can use make targets to run spin instances, run tests and terminate instances.

# spin instances, run tests and terminate instances
make test/automated

Individual targets:

# provision ec2 instances (test/automated/ansible/inventory.ec2 will be created)
make test/automated/provision

# run harvest tests using test/automated/ansible/inventory.ec2 inventory
make test/automated/harvest

# run packaging tests using test/automated/ansible/inventory.ec2 inventory
make test/automated/packaging

# run packaging docker tests using test/automated/ansible/inventory.ec2 inventory
make test/automated/packaging-docker

# terminate instances in test/automated/ansible/inventory.ec2
make test/automated/termination

  • Installation tests
  • Fuzz testing

Support

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

New Relic offers NRDiag, a client-side diagnostic utility that automatically detects common problems with New Relic agents. If NRDiag detects a problem, it suggests troubleshooting steps. NRDiag can also automatically attach troubleshooting data to a New Relic Support ticket. Remove this section if it doesn't apply.

If the issue has been confirmed as a bug or is a feature request, file a GitHub issue.

Support Channels

• New Relic Documentation: Comprehensive guidance for using our platform
• New Relic Community: The best place to engage in troubleshooting questions
• New Relic Developer: Resources for building a custom observability applications
• New Relic University: A range of online training for New Relic users of every level
• New Relic Technical Support 24/7/365 ticketed support. Read more about our Technical Support Offerings.
