Flex is an application-agnostic, all-in-one New Relic integration with which you can instrument any app that exposes metrics over a standard protocol (HTTP, file, shell) in a standard format (for example, JSON or plain text): you create a config file, start the Infrastructure agent, and data starts pouring into New Relic.

Flex can take any input using data source APIs, process it through functions, and send metric samples to New Relic as if they came from an integration.

For a quick introduction on Flex, read our blog post. You can also have a look at the 200+ example integrations!

Flex requires a New Relic account and is compatible with the following operating systems/platforms:

• Linux
• Windows
• Kubernetes

For more information on compatible distros and versions, see the Infrastructure agent compatibility page.

Flex comes bundled with the New Relic infrastructure agent. To install the infrastructure agent, see Install the infrastructure agent.

If you're using Kubernetes, see Configure Flex in Kubernetes.

The Flex step-by-step tutorial is a great starting point.

All examples are located in /examples.

Note that some examples may use features that are experimental (not officially supported) or deprecated.

• How to configure Flex
• Flex under Kubernetes
  • Integration with Pixie
• Data sources / APIS
• Data transformation functions
• Experimental functions

While developing your own Flex integrations, you can use Flex without the New Relic Infrastructure agent for debugging. For more information, see Development.

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

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