Pass Infrastructure agent parameters to an on-host integration

Problem

You have config parameters defined in the infrastructure agent and you want to pass the parameters to an on-host integration.

Solution

You can pass config parameters set in the agent to on-host integrations by adding the variable passthrough_environment to the infrastructure agent's configuration file.

For example, if you want to pass the proxy options configured in the infrastructure agent to an integration, add the following configuration to the infrastructure config file:

passthrough_environment:
  - HTTPS_PROXY
  - HTTP_PROXY
  - MY_REDIS_PASSWORD

Starting with infrastructure agent 1.14.0, you can also define environment variables as part of the integration configuration file as shown below (passthrough_environment config is also required):

integration_name: com.newrelic.redis
instances:
  - name: redis-metrics
    command: metrics
    arguments:
      hostname: localhost
      port: 6379
      password: {{MY_REDIS_PASSWORD}}
