Environment variables are a way to store configuration and secrets outside of your code. The following tables display the mandatory variables and runtime specific variables that you can set to monitor your Azure functions with New Relic.

## Mandatory environment variables

Regardless of your runtime, you must set the following environment variables to monitor your Azure functions with New Relic:

| Variable Name           | Description                                                     |
| ----------------------- | --------------------------------------------------------------- |
| `NEW_RELIC_ACCOUNT_ID`  | Specifies your New Relic account ID                             |
| `NEW_RELIC_LICENSE_KEY` | Specifies your New Relic ingest key, overriding Secrets Manager |

## Additional environment variables

Based on your runtime, you can set the following environment variables to further configure the New Relic Azure Functions monitoring:

### Node.js

| Environment variable | Default value | Options       | Description                                                                         |
| -------------------- | ------------- | ------------- | ----------------------------------------------------------------------------------- |
| `NODE_OPTIONS`       |               | `-r newrelic` | **Required**: Inject the agent before your Azure application functions are invoked. |
| `NEW_RELIC_APP_NAME` |               |               | Set the application name, though it is not used in the New Relic UI                 |

You can find more environment variables in our [Node.js configuration documentation](https://docs.newrelic.com/docs/apm/agents/nodejs-agent/installation-configuration/nodejs-agent-configuration/).
