Streaming Logs to New Relic
New Relic is an application monitoring platform that includes a logging service. To stream logs to New Relic, you will first need to generate an API key. Make sure you create an INGEST - LICENSE key.

Enter httpsX-License-Key
and enter the license key you generated above.
