Citizens report slow permit lookups through API Gateway in front of an Oracle Function. Which metric pair best separates gateway overhead from time spent in the Function backend?
Select an answer to reveal the explanation.
Short Explanation
Gateway Latency is the whole front-door stopwatch; IntegrationLatency is how long the Function or HTTP backend alone held the baton. Comparing them shows whether the doorway or the back office is slow.
Full Explanation
API Gateway emits metrics in the oci_apigateway namespace automatically, including HttpRequests/HttpResponses, Latency (gateway plus integration plus internal), IntegrationLatency (time in the Function or HTTP backend), and backend versus gateway HTTP status. That split lets developers see whether slowness or 5xx originates at the gateway or in the Function behind it. OKE node metrics, Audit logs, and RUM answer different troubleshooting questions.
