Answering your Domain Inspector questions

Domain Inspector provides you with a dataset and visualizations that offer real-time visibility and historical reporting of domain-level metrics delivered by a Fastly service. It allows you to monitor traffic for a fully qualified domain name without requiring you to send log data to a third-party data collector.

Domain Inspector aggregates domain response data received by a specified service and presents that information either as visualizations in the web interface or as a JSON-formatted data stream.  Examples of the kinds of domain data aggregated include requests, edge or origin response status codes, and cache hit ratios. For more detailed information about specific features check out our documentation.

• Proactive domain monitoring: Proactively monitor and react in a timely manner to domain traffic issues that arise at the origin or the edge.

• Live event monitoring: Get end-to-end visibility of domain traffic during critical calendar and live events. 

• Troubleshoot errors: Account for every origin/edge response, origin/edge byte, and status code to get insight into origin or edge failures.

• Individual domain tracking: Enumerate any domain for individual domain tracking or domains set up for specific business visibility.

• Evaluate your investment: Quantify the extent to which Fastly services reduce origin infrastructure and egress costs, especially with shielding.

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 are 45 days within the Enterprise level for Domain Inspector.

We currently support up to 500 unique domains within a single Fastly service.  Contact support@fastly.com to discuss options in supporting a higher domain count.

Yes, wildcard domains (e.g. *.fastly.com) are supported. However, due to the unlimited cardinality with wildcard domains, we will aggregate all provided domain metrics under a single wildcard domain name entry.

Customers who have a paid account and a contract for Fastly’s services can also purchase Domain Inspector at the Enterprise level for a separate additional monthly fee.  Contact us at sales@fastly.com to discuss access.

Fees for Domain Inspector are changed per each unique domain sending traffic through Fastly each month. This is tiered based usage pricing where the number of domains place you into a committed tier with a consistent charge every month. Any domains used above the committed amount will be charged an overage rate. To discuss pricing in more detail, contact sales@fastly.com.
