Hi Johan, Thanks for you information. It works follow you advice to find these built-in measurement. But I need more probes (maybe all of them, or large set) and RTT data for just one day. It is impossible for me to do it manually. Is there any tool for me to select a group of probes or measurements in the rtt-fixed map?

Hi Johan,

Thanks for you information. It works follow you advice to find these built-in measurement. But I need more probes (maybe all of them, or large set) and RTT data for just one day. It is impossible for me to do it manually. Is there any tool for me to select a group of probes or measurements in the rtt-fixed map?

I think you’re mis-understanding how the built-ins work. These measurements do run on all the probes and therefore have the data for all of the probes. In the download tab, you can then select the day you want and download the results. For instance: https://atlas.ripe.net/api/v2/measurements/1009/results/?start=1545350400&stop=1545436799&format=json This gives you all the results for all the probes for 21 December 2018. You can of course also select a day in the map view itself using the time travel slider. Again, be aware that these results are huge so you should use curl or our Python libraries to get and process these results. You can find all the RIPE NCC tools here: https://github.com/RIPE-NCC <https://github.com/RIPE-NCC> The specific ones you want are: https://github.com/RIPE-NCC/ripe-atlas-tools <https://github.com/RIPE-NCC/ripe-atlas-tools> https://github.com/RIPE-NCC/ripe.atlas.sagan <https://github.com/RIPE-NCC/ripe.atlas.sagan> https://github.com/RIPE-NCC/ripe-atlas-cousteau <https://github.com/RIPE-NCC/ripe-atlas-cousteau> Let me know if I answered your question. If not, I will try to help you further. Kind regards, Johan ter Beest

This is the built-in Ping measurement towards a.root

Let me know if you need any more information.

Thanks. I can receive and respond. It weird that I can receive mail from this mailing list now only after I sent a mail. Was my mail account treated as a dead one? : ) Davey
