Business stakeholders want a CloudWatch metric for permits submitted, emitted from the application's structured logs, without flooding the API with separate PutMetricData calls. Which approach should developers implement?
Select an answer to reveal the explanation.
Short Explanation
EMF is the packing slip inside the log box: one structured write, CloudWatch lifts the metric out. Spamming PutMetricData on every heartbeat is how request paths drown themselves.
Full Explanation
CloudWatch embedded metric format allows applications to publish metrics by writing specially structured log events that CloudWatch extracts into metrics, reducing the need for high-volume synchronous PutMetricData from the request path. Unstructured logs alone, pathological PutMetricData usage, or local-only storage do not implement EMF-based custom metrics.
