In December 2019, Infrastructure agent version 1.8.0 began supporting a newer configuration format that makes use of a single configuration file (instead of two separate files), and provides other improvements. This document will explain how this newer format works.
The older standard configuration format is supported by current Infrastructure agents.
For an introduction to configuration, see Config overview.
An on-host integration's configuration YAML must have an
integrations top-level section containing a YAML array, where each entry represents an integration and its configuration.
For each integration entry, only the
name property is mandatory. The other properties are optional.
integrations: # New Relic integration that does not require any configuration - name: nri-docker # New Relic integration that gets its configuration from the environment - name: nri-mysql env: PORT: 3306 USERNAME: newrelic PASSWORD: 123456789 # to hide this field, read the secrets management documentation # Any free-form integration executed via a user-provided command - name: my-own-integration exec: python /opt/integrations/my-script.py --host=127.0.0.1
You can have as many configuration YAML files as you want and can group your integration instances.
We recommend linting the YAML configuration files before using them to avoid formatting issues.
This configuration format does not require an agent restart. When saved, changes are detected and implemented immediately. This means that saving intermediate configuration changes may cause the integration to stop working.
This is a list of the general properties used to configure an integration. For more details about using these properties, including example values, see the documentation following the table.

The remainder of this document describes config properties grouped by their functionality:
- Select an integration to run
- Pass configuration to the integration command
- Configure how the agent executes integrations
There are two properties to select which integration will run:
The only mandatory property across all on-host integrations is
name. The remaining properties specified in this document are optional.
integrations:- name: nri-docker- name: my-integrationexec: /usr/local/bin/my-integration --metrics --inventory
Often integration executables need to receive a configuration to work properly (for example, hostname and port of the monitored system, user credentials, etc.).
The Infrastructure agent allows you to configure the integration commands in three ways (which you can combine):
- Command-line arguments, passed in the
- Environment variables, using the
- Configuration files, whose path needs to be passed through environment variables or command-line arguments (see the config) property.
integrations:- name: my-integrationexec: /opt/path/bin/script --host 127.0.0.1 --port 8081- name: nri-mysqlenv:STATUS_URL: http://10.0.0.3/server-status?autoREMOTE_MONITORING: true
The properties of this section modify the way the Infrastructure agent executes and interacts with the integrations, or the way the agent decorates the integrations' data.
The main difference between these formats is that the older configuration format uses two separate configuration files (a
INTEGRATION_NAME-definition.yml file and a
INTEGRATION_NAME-config.yml file) and the newer version uses a single configuration file.
Here are some of the features added by the newer configuration functionality:
- Flexible configuration via command-line arguments, environment variables, or external files.
- Ability to group different integrations in the same file.
- Hot reload: adding a new integration or changing its configuration does not require restarting the agent.
- Timeouts: if an integration doesn't respond before a user-specified time, the integration process is killed and restarted.
Not all on-host integrations come with the newer configuration format, but you can update the configuration to the new format for all on-host integrations to take advantage of the new features.
The following YAML shows an example Apache integration configuration using the older configuration format. Note that this configuration will still work with newer agents, but we recommend updating your integrations to take full advantage of features.
integration_name: com.newrelic.apacheinstances:- name: apache-server-metricscommand: metricsarguments:status_url: http://127.0.0.1/server-status?autoremote_monitoring: truelabels:env: productionrole: load_balancer- name: apache-server-inventorycommand: inventoryarguments:remote_monitoring: truelabels:env: productionrole: load_balancer
To update an older integration configuration to the new format, you must perform two steps:
- Rename the
instancestop-level section to
- Remove the
integration_nametop-level section and add it to each integration entry. You are no longer required to keep a separate file for each integration type and you can group your legacy integration entries in the same file as other integrations.
The new version of the Apache integration config:
integrations:- name: apache-server-metricsintegration_name: com.newrelic.apachecommand: metricsarguments:status_url: http://127.0.0.1/server-status?autoremote_monitoring: truelabels:env: productionrole: load_balancer- name: apache-server-inventoryintegration_name: com.newrelic.apachecommand: inventoryarguments:remote_monitoring: truelabels:env: productionrole: load_balancer
Please note that because the older configuration format doesn't support hot reloading. You will need to restart the Infrastructure agent to remove the old integrations configuration (otherwise the old instances will coexist with the new ones).
