HTTP 502 errors from NodeNorm RENCI

[gaurav]

We're seeing 502 errors on NodeNorm RENCI.

Next step:

• Confirm whether this is a Sterling ingress issue or a NodeNorm issue (by seeing if the 502s are in our logs as well).
• Confirm whether this is related to either Sterling incoming traffic levels (if it is a Sterling ingress issue) or NodeNorm traffic or something else.
• It might be useful to provide a NodeNorm dashboard that taps into NodeNorm logs to answer questions about 502 error rates, CPU/memory issues and others.
• If it is a traffic issue, consider using API keys to monitor NodeNorm traffic.
