It’s comparatively easy to see that one thing is improper together with your community utilizing DNS knowledge. A spike in NXDOMAIN responses or different errors normally serves as a transparent indication that one thing is amiss.
The following step—diagnosing the supply of the issue after which truly doing one thing about these errors—is commonly a heavier carry. It’s a knowledge downside. Any authoritative DNS supplier value its salt will present you what number of NXDOMAIN responses you’re getting. But, few present the contextual info community that groups must uncover the supply of these errors, which may come from a number of instructions and contain a number of DNS knowledge factors.
Up so far, authoritative DNS suppliers have approached this problem in one in every of two methods:
Overwhelm community groups with knowledge
A number of authoritative DNS suppliers provide uncooked knowledge feeds as an add-on function. These definitely present all the data a community staff would wish to troubleshoot misconfigurations and diagnose the foundation explanation for DNS errors.
The issue: discovering the needle within the haystack. Uncooked knowledge feeds sound good, however they normally find yourself creating extra work for community groups, who must course of and analyze the information to find the underlying explanation for community points. Even when the staff is pushing the DNS feed into an information lake, SIEM, or processing platform, it might probably take some time to construct out the dashboards and workflows to transform it into usable info. Even then, it isn’t at all times clear that you should have the correct info if you want it.
The consequence: community groups spend extra time looking for the data they want and fewer time truly diagnosing and fixing challenges.
Present solely primary knowledge
Different authoritative DNS suppliers take the other strategy, offering only a easy dashboard with primary info. Often, this takes the type of a desk of NXDOMAIN responses organized by geographical location, IP vary and some different factors.
The benefit of this strategy is that the information is pre-processed and simple to digest, saving a variety of work on the again finish to construct, configure and handle evaluation infrastructure.
The first drawback is that the information normally just isn’t complete sufficient to account for all the explanations community errors occur in the true world. There may be not sufficient flexibility to seize all of the nook circumstances or take a look at a difficulty by a number of lenses. What you see is what you get—and that’s typically not sufficient.
The consequence: community groups get simply sufficient info to want that they had extra. They’ll establish primary points, however their skill to actually troubleshoot and get to root causes is proscribed.
