The [Historical Stats API](https://www.fastly.com/documentation/reference/api/metrics-stats/historical-stats/) and the [Real-Time Analytics API](https://www.fastly.com/documentation/reference/api/metrics-stats/realtime/) now support ten new metrics for troubleshooting DDoS protection challenges. These metrics cover challenge and token creation, validation outcomes, and Private Access Token (PAT) challenges issued during DDoS protection rule enforcement.
