RIPE Atlas: DomainMON is Here

A few weeks ago we gave you a heads up about a new visualisation tool in RIPE Atlas called DomainMON, and we're pleased to announce that this is now available for all RIPE Atlas users with available credits.

What it is

For some time now, RIPE Atlas users have been asking us for a tool to let them monitor their own domains (or any domain of their choosing), similar to what DNSMON does for high-level domain name servers. This feature has been available for several weeks to the RIPE Atlas testers group and we're happy to announce that it's now publicly available to all RIPE Atlas users. 

DomainMON is powered by the same technology as DNSMON , which monitors various important DNS root and TLD name servers. DomainMON is like a "personal" version of DNSMON that can be used to monitor your own name servers - or any others of your choosing. It visualises the results in the same matrix view as DNSMON, giving you a quick overview of the quality of service offered by your name servers. You use your own RIPE Atlas credits to make the measurements, so you generally need to host or sponsor a RIPE Atlas probe or anchor in order to take advantage of this new tool.*

How to use it

You can set up measurements in DomainMON with a handy wizard, which will guide you through the process. Once you enter the domain you want to monitor (usually a DNS zone with a SOA record), the wizard will automatically detect and present a list of name servers that serve the domain; however, you can also manually select the servers you're interested in. For example, maybe you're interested in how servers in one particular country serve your domain, in which case you could choose to use servers located only in that country.

If the domain you've entered is already being monitored by DNSMON, you'll get a notification to that effect.

Unlike with DNSMON (which uses RIPE Atlas anchors to perform measurements), DomainMON uses individual probes for its measurements. You can select between one and 50 probes (the maximum limit is to prevent over consumption of credits and overloading the visualisation). You can set the measurement type and frequency, and you'll get a handy graph showing how many credits your measurements will consume each day.

Once you've set up your measurements, you can see them visualised by clicking on the "visualise" button at the top of the page. You'll see the same matrix overview as with DNSMON.

The control panel is the same as with DNSMON, too, giving you just as much control over the way the measurement results are displayed. You can set the thresholds for the different quality parameters (i.e. what is considered "good" (green), "intermediate" (yellow) and "poor" (red)) for percentage of unanswered queries and response time. You can also filter results by protocol, adjust the time range represented, and zoom in and out.

The results are near real-time (to within approximately five minutes) and give a snapshot of your domain or, if you click the "continually update results" button on the control panel at the top right of the matrix, you'll get a dynamically updated view.

We hope you'll find this new tool useful, and are interested in how you'll use it. Let us know if you find some interesting results or want to share you own use case on RIPE Labs.
