Edge DNS reports

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

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.

Edge DNS Availability report

The Edge DNS Availability report tracks service availability (uptime) of the top-level DNS name servers for your selected contract and time frame up to 90 days.

Data granularity

This report returns up to 90 days of data.

Filters

  • Contracts. Each contract is assigned a set of top-level DNS name servers. Availability is calculated by looking at the uptime of the name servers for your contract.

Graphic visualization

  • Availability By Time. Graphic visualization displaying availability percentages for the selected time frame. This widget updates every 10 minutes. When viewing the report over longer time frames, availability can summarize across wider intervals (for example, every hour). Hover over the graph to see the percentage availability for a give date and time.

Metrics

  • Avg Availability %. Average availability percentage for the selected time frame.

  • Max Availability %. Maximum availability percentage for the selected time frame.

  • Min Availability %. Minimum availability percentage for the selected time frame.

Edge DNS Zone Detail report

The Edge DNS Zone Detail report provides even more traffic data than the Edge DNS Today report for one selected zone and time frame up to 14 days.

The report provides a heat map of query source locations by geographic region, along with graphic visualizations and analytics of DNS requests. Additionally, the report provides hits per second over time, record-level counts, and top nonexistent domains (NXDOMAINs) for the selected time frame.

Record-level counts are helpful to learn about use at the label level. Top NXDOMAINs help characterize and understand a common attack vector known as random subdomain, where an attacker gains control over a subdomain of a target domain.
