You can now use 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/) to troubleshoot backend Compute errors. Sixteen new metrics attribute each backend Compute error to TLS, HTTP, DNS, connection issues, or other sources.
