Question

From the article on Clarifications on Metrics Requirements

Performance Metrics: your interpretation is correct. Rejected API calls would incorrectly skew performance results. It is still important than when a data holder rejects an API call it does so for valid reasons and it can provide evidence of the reason(s) for rejection.

Should Rejected API calls (due to traffic thresholds) also be excluded from Average Response Metrics ?

Answer

Yes. Even error responses should still be timely for a client. It is appropriate to include the response time for rejections in the average response metrics.
