Origin Inspector Real-time API
IMPORTANT: Unlike other Fastly APIs, the base URL for Origin Inspector Real-time API is https://rt.fastly.com.
Origin Inspector offers a real-time JSON-formatted data stream providing visibility into responses delivered from your origin servers to Fastly. The API offers a standardized set of data to report in real-time every origin response, byte, and status code received by a specified service in one-second periods up to the last complete second.
IMPORTANT: Origin Inspector is an optional upgrade to Fastly service plans and must be enabled for each service using the enablement API.

Data model
AggregateDelay | integer | Offset of entry timestamps from the current time due to processing time. | |
Data | array | A list of report entries, each representing one second of time. | |
Timestamp | integer | Value to use for subsequent requests. |
Measurements data model
A measurements object provides a count of the total number of responses received by Fastly from your origin servers in the reported time period, for the relevant POP and backend name as specified in the entry. It also includes the number of responses for specific HTTP response status codes and for status code ranges. This dataset is sparse: only the keys with non-zero values will be included in the record.
Where a specific status code does not have a field in this model (e.g., 429 Too Many Requests), any responses with that code will be counted as part of the range count (4xx in this case) but will not be separately identified in the data.

Entry data model
Each reporting period is represented by an entry in the Data property of the top level response and provides access to measurement data for that time period, grouped by origin name and optionally by POP. The datacenter property organizes the measurements by Fastly POP, while the aggregated property combines the measurements of all POPs.
aggregated | object | Groups measurements by backend name. | |
datacenter | object | Groups measurements by POP, then backend name. See the POPs API for details about POP identifiers. | |
recorded | integer | The Unix timestamp at which this record's data was generated. |
