ThousandEyes DNS Monitoring
ThousandEyes DNS Monitoring tracks DNS servers, resolvers, and records across customer and provider networks to identify availability, performance, and security issues. It covers on-premises, hosted, and third-party DNS servers, checking availability, resolution speed, and record mappings. Tests can discover DNS infrastructure, trace routing and paths, measure resolver responsiveness, and check record accuracy. The service can trace a record's DNS hierarchy from top-level servers to the authoritative server, and verify the DNSSEC keychain from the bottom up. Users can configure and export alerts for availability, record mappings, DNSSEC, and record changes, including changes that may indicate cache poisoning. Alert destinations include email, SMS, webhooks, PagerDuty, Slack, ServiceNow, AppDynamics, Splunk, Webex, and Microsoft Teams. The Network & App Synthetics plan is an annual subscription priced according to visibility needs and test units; pricing is on request. A 15-day trial includes Cloud Agents in 20+ global locations and Enterprise Agents for customer infrastructure and cloud VPCs.
