Support passing license_key into newrelic.agent.initialize

Is your feature request related to a problem? Please describe.

I’d like to have the option to pass the license key directly into the agent initialization function. I don’t want to include it in the newrelic.ini file, since the key is a secret and is only available to the application during deployment.

Feature Description

if my_app.config["environment"] in ("stage", "live"):
    newrelic.agent.initialize(
        config_file="newrelic.ini",
        environment=my_app.config["environment"],
        log_level=my_app.config["loglevel"],
        license_key=my_app.config["new_relic_license_key"],  # <-- this is what would it look like
    )
    newrelic.agent.register_application()

Describe Alternatives

I could also have newrelic read the license key from the env, but our app doesn’t use the env for configuration as of yet. And splitting configuration options over multiple avenues would be a bad design, so we’d rather not do it.

As a workaround, we currently manipulate os.environ before importing any newrelic modules.

Additional Context

I tried to write a PR myself, but the config parsing for newrelic is wild, and I couldn’t get it to work by myself.

OH! You’re in the EU! Ha!! OK. You’ll also need to set the host!

from newrelic.core.config import default_host
newrelic.agent.global_settings().host = default_host("YOUR_KEY_HERE")

Yeah thanks for bringing this up! We should probably consider API usage when using an EU license key. This is something we’ll chat about on the team!
