Using Atlas for Monitoring of Anycast DNS
Hi! I want to monitor an Anycasted authoritative name server: - are all nodes responding - are all nodes in routing ... So I thought about starting a long term DNS measurement with plenty of probes and NSID queried. Then, checking the results I should see every possible NSID if there are for more probes than Anycast-nodes. Does anybody have done that (or similar) already and want to share code? Can the RIPE Atlas Status Checks be used for such monitoring? Thanks Klaus

There is plenty of that going on already. Please check if you can make use of someone else's measurements before deploying your own, especially if you want to monitor someone else's servers. They may already be in there somewhere and duplicating efforts is less than ... optimal. :-) Best regards, /Lars-Johan Liman Operator of anycast servers for the root, and several TLDs. :-) #---------------------------------------------------------------------- # Lars-Johan Liman, M.Sc. !

How will I know if such measurements exists and how will I find these measurements? And how will I make sure that these measurements are not stopped and my monitoring wakes me at midnight? regards Klaus

As far as I know, there is no search engine for RIPE Atlas measurements ("find me all the DNS measurements against 8.8.8.8"). I've been told it is, at least partially, for privacy reasons (it would be useful for some people to learn what is monitored).

Hi, There is in RIPEstat. See for example https://stat.ripe.net/8.8.8.8#tabId=activity Philip
The new Measurements listing has search capability: https://atlas.ripe.net/measurements/?search=8.8.8.8&kind=6%2C7 That might help.

Unfortunately, the status checks system is currently limited to ping measurements, but we're interested in how some of you might like to see DNS support rolled in. In the interim though, you can use: * The measurement-latest API (https://atlas.ripe.net/api/v1/measurement-latest/<measurement_id>/) to fetch the most recent result at any given time * Sagan (https://github.com/RIPE-NCC/ripe.atlas.sagan) to parse the results and find what you're looking for I hope that helps :-)
