DNS Monitoring with ThousandEyes
DNS is a critical component of application delivery and security.
If users can't access your DNS records or access the correct records, your service is unavailable.
ThousandEyes monitors your externally hosted and on-premises DNS infrastructure.
Including both authoritative and caching servers, so you can identify and troubleshoot DNS availability, performance, and security issues.
Three types of tests collect data about your DNS infrastructure.
DNS server tests measure the availability and resolution time of each of the authoritative or caching-named servers.
You'll have data about network loss, latency, and the path topology to each DNS server whether hosted in your own infrastructure or hosted by external providers.
You'll be able to quickly locate specific name servers or network segments that are causing poor performance.
In addition, you'll be able to detect DNS record accuracy and alert whenever a record is missing or incorrect.
DNS trace tests query through the entire hierarchy from root servers to your authoritative server.
You'll be able to ensure that your critical records are being served from the named servers that you expect and measure the availability, number of queries, and total query time.
DNSSEC tests validate the signatures returned by each server in a sign zone.
From each monitoring location, you'll be able to see the trust tree and data chains so you can ensure DNSSEC doesn't affect availability for your domains.
Setting up tests and collecting data is easy.
Any DNS test can monitor performance from locations around the world using cloud agents to simulate an external customer-facing experience.
In addition, you can use enterprise agents to run tests from points within your own network in order to understand an employee-facing experience.
All DNS tests include the ability to set up custom alerts and notifications, so you can be notified of DNS resolution failures or record mismatches.
Also, take advantage of ad hoc or scheduled performance reports.
You can easily save data for your records and share interactive links with your team or service providers.
In a matter of minutes, you can have DNS tests running and begin to identify specific trouble spots to optimize your performance.
