Origin Inspector

Origin Inspector provides you with a dataset and visualizations that offer real-time and historical visibility into responses delivered from your origin servers to the Fastly Edge Cloud. It allows you to monitor origin traffic without requiring you to send log data to a third-party data collector.

Specifically, Origin Inspector aggregates origin response data (for example, egress bandwidth, response status codes, and number of origin responses) received by a specified service and presents that information either as visualizations in the web interface or as a JSON-formatted data stream.


Origin Inspector can be purchased as part of either Fastly's Essential or Professional Edge Cloud packages.

Customers with a paid account with a contract for Fastly's services can purchase Origin Inspector at the Enterprise level for a separate, additional fee rather than as part of an Edge Cloud package. Contact us at sales@fastly.com to discuss this option.

Limitations and considerations

We limit you to 250 origins per service with Origin Inspector. Reach out to support@fastly.com for details on how to increase this limit.

In addition, real-time data is reported in one-second periods up to the last complete second for a 120-second window. Historical data aggregation and retention timeframes, however, vary based on the Origin Inspector level you have purchased.

Fees for Origin Inspector are charged based on the number of origins sending traffic through Fastly. Where applicable, an “origin day” is one unique origin per calendar day per service. To discuss pricing in more detail, contact sales@fastly.com.
