Change Nginx logging on frontend and API nodes so that it reports the X-Forwarded-For address, instead of the address of the proxy server.
I'm doing this now because we've had a few API latency alerts in the past month, and troubleshooting them is very difficult without good IP address information. The last alert was for a 1/2-hour period of high response times (> 1 sec), so I'm taking care of this now so we can fix the issue, since it's not a lot of work.
