Here’s a sample configuration to monitor the query latency from the 5 DNS providers we mentioned previously. After entering the domains you want to use in your query and the DNS server IPs just restart netdata and the DNS query charts should be visible within seconds. Then just go to the Netdata configuration directory (usually /etc/netdata) and run. Let’s see how to do this using the primary DNS server IPs from 5 of the most popular DNS providers.Īs a prerequisite you need to sign up for a free Netdata Cloud account and install the open source Netdata agent on the client from which you want to monitor DNS query response times. Using Netdata you can quickly probe and compare DNS query response times across multiple DNS servers. Monitoring DNS Query Response Time with Netdata There are many DNS options available today offering free, fast and secure DNS services. The default DNS server in use may not always be the best choice. There are many factors which influence the response times of a particular DNS provider, such as the geographic location of the server or how much traffic it receives. This will help you to correlate where the problem is triggered by DNS latency and where it isn’t.ĭNS response times can be optimized by (among other things) choosing the right DNS provider. To understand how DNS response times affect the performance of your application it is important to monitor it continually along with other metrics of application and infrastructure performance. What DNS Query Response Time metrics are important to monitor - and why? When it comes to DNS response times, the lower the better, and generally values less than 100ms are considered to be in the acceptable range (depending on the application). DNS Query response time is the time it takes a Domain Name Server to receive the request for a domain name’s IP address, process it, and return the IP address to the browser or application requesting it.
