Datadog has introduced new DNS monitoring features to help troubleshoot end-to-end DNS issues and ensure the performance and availability of applications. The DNS view in Network Performance Monitoring provides insights into internal DNS server health, service discovery, and Synthetic DNS tests for proactive detection of failures and misconfigurations. These features enable users to assess the health of all internal DNS servers, investigate DNS communication from the client side, troubleshoot latency and failure issues, correlate DNS performance with server monitoring data, and detect irregularities in DNS record mapping and resolution times. Datadog's unified visibility into DNS traffic helps users identify problems with individual DNS servers, correlate DNS traffic with server health, and proactively monitor their DNS records for potential issues.
