Edge DNS provides a secure, high-performance, scalable, and highly available edge service for authoritative DNS. Use the these report to check service availability (uptime), monitor traffic, analyze patterns for troubleshooting and threats, compile information for others, and forecast capacity.

If you are using Shield NS53, you can also generate reports on Shield NS53 traffic, events, and service availability. Shield NS53 is a DNS proxy that protects your origin infrastructure, such as an authoritative DNS name server, firewall, or a global server load balancer, from DNS resource exhaustion attacks.

You can access the reports from the REPORTS page. See How to use reports.

The next sections describe the data granularity, filters, graphic visualizations, and metrics associated with each report.

For additional information about these reports, see also Monitor and report on service, traffic, and threats in the Edge DNS user guide help.

DNS Requests vs Responses. Graph that shows how much traffic was received by Shield NS53. An increase in requests and responses shows there was an increase in your DNS traffic. If the Responses value dips significantly below Requests, this might indicate there’s an issue that should be evaluated. Hover over the graph to see the precise number of requests and responses that occurred. You can also click Requests or Responses in the legend to show or hide this data in the graph.
DNS Requests Broken Down by Region. Graph that shows the number of DNS requests based on AS regions.

The DNS Requests Broken Down by Region and DNS Responses Broken Down by Region graphs may take some time to load.
DNS Responses Broken Down by Cached. Graph that shows the number of DNS responses based on cache level. This graph lets you see how many requests were served from a resolver's cache. The graph compares this value to the total number of DNS responses. You can hover over the graph to view response data. You can also click items in the legend to show or hide data in the graph.
DNS Responses Broken Down by Type. Graph that shows the number of DNS responses based on how many were positive. A positive response indicates the request is valid. As a result, Shield NS53 can answer the request from its cache or request a response from your authoritative name server. A negative response indicates that the requested domain is invalid. As a result, Shield NS53 drops the request and based on the request, serves an NXDOMAIN or refused response. You can hover over the graph to view DNS response data. You can also click items in the legend to show or hide this data in the graph.
