In order to finish installing the APM agent, you need a valid New Relic license key.

Go to the API keys page in the UI and click Create a key, and then create an ingest-license key type. Alternately, if you have an existing license key, click ..., then click Copy key.

If you don't already have a New Relic account, sign up to get your license key. It's free, forever!
