SolarWinds monitors your connection quality by keeping track of how quickly the server responds to your queries and then compares that to a list of pre-set IPs. If the response times are low, the tool will notify you of an issue. You aren’t forced to do everything manually either, since the tool will let you know if your server gets too many requests at once, allowing you to act even while you’re away.
When it comes to hardware health, you can look at the health of your servers based on a variety of elements like its status, CPU, current temperature/fan speed, and many others. If you’re having difficulties with any of these, you’ll see a warning flag crop up.

Nagios XI is a big name in the network monitoring world; however, they’ve also included an excellent DNS monitor. Nagios XI lets you keep track of queries, servers, and protocols, making it much easier with its DNS Query Nagios XI Monitoring Wizard.
The tool was created with fast-paced environments in mind, meaning any DNS issues in your network should be detected within seconds or minutes. This lets you keep your mind off of DNS issues, as you can respond to them immediately in case anything important happens.
One of the biggest reasons Nagios XI is so famous is that it offers a variety of excellent plugins. So naturally, there are also quite a few plugins made to help you with DNS monitoring, such as Check DNS Replacement, check_dyndns_logon, and numerous others.

The most significant downsides of the ManageEngine are that its UI can be a bit confusing and a tad unfocused as software. Although it offers a lot of things it does well, it doesn’t top the charts in any of them.
A free version lets you get five apps or servers monitored. The professional edition goes from $945 for 25 apps or servers up to 250 apps or servers at a price tag of $7,195. There’s also an enterprise edition that goes up to 5000 apps or servers.
ThousandEyes is the most transparent tool on this list by far. The tool can monitor various apps and servers and look at any connected servers’ availability and resolution times.
The tool has maintained great user-friendliness and poured quite a bit into its new user experience. Its autodiscovery features ease off a lot of the pressure that more unique users of DNS monitors might face.

Some might have noticed we didn’t list BIND 10 as one of the entries in this list, despite it being the most popular DNS monitoring software. We didn’t record it because its popularity is simply a matter of convenience and price. It’s convenient to have because it comes pre-installed with most Unix/Linux installations, it’s free, and it’s open-source. However, it simply doesn’t stack up to most other tools on this list.
All of the tools above are great, and as always, the most important thing is to keep in mind your needs. Our 8th pick might just be your 1st. We feel that the SolarWinds Server & Application Monitor offers the most consistent, quality performance out of any DNS monitor on the market.
