LatencyMON Widget Y axis in milliseconds
by Marat Khalili 10 May '16

10 May '16

I'm using LatencyMON <https://atlas.ripe.net/docs/tools-latencymon/> widget to monitor my network performance. It's very convenient. Unfortunately, it always loads with latency shown in %% (of what?), not in milliseconds, so I have to make one extra click in order to view actual milliseconds. Is there some hidden switch that would make milliseconds the default? Shouldn't it be initially default in the first place? -- With Best Regards, Marat Khalili

ping measurements and high lts
by Clinton Work 10 May '16

10 May '16

When looking at the ping measurement json results I found some probes are reporting a very high lts (last time synchronized). Is it normal for very high lts values to be reported? These two anchors seem chronic: Probe 6161, max lts 65807 Probe 6132, max lts 23905 ================================= Clinton Work

Okay thank you for the answer. Should he therefore leave the "OFF"? Le 02/05/2016 17:01, Micha Bailey a écrit : > Essentially, this is a dynamic DNS service bound to the probe.

Hello, In the edition of general probe of my information, I see that there are marked "DNS" with several choices: OFF, SINPLE or obfuscated. I would have wanted to know what it matched? And what he had to choose. Thank you in advance.

An article/FAQ entry about probe troubleshooting
by Ondřej Caletka 02 May '16

02 May '16

Hi all, it seems that failing probes are getting more and more to be an issue, possibly due to USB flash drive failure. I think it would be nice if there was an article / FAQ entry with some official troubleshooting procedures, so we could just send a link to anybody complaining about non functional probe. Is there something like this on the roadmap? Perhaps we as the community could make something up: - how to check whether the port probe is connected to has proper IP and DNS parameters and is allowed to establish a SSH session to TCP port 443 in the Internet (beware of DPI firewalls that allow HTTPS but not SSH over 443) - how to check the LED status and the SOS list at the probe page (the current LED explanation in the FAQ is too techy and even power users like me still don't understand all presented states :) ) - how to diagnose USB flash drive failure, how to force reformatting the flash drive and how to replace it with a new one What do you think? Cheers, Ondřej Caletka CESNET

New on RIPE Labs: How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
by Mirjam Kuehne 29 Apr '16

29 Apr '16

Dear colleagues, RIPE Atlas backend applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs: https://labs.ripe.net/Members/andreas_strikos/how-elasticsearch-and-kibana-… Kind regards, Mirjam Kuehne RIPE NCC

Failure Rate on Atlas Probes
by Jonathan Brewer 23 Apr '16

23 Apr '16

Hi All, What's the known failure rate of Atlas probes, and the mean time before failure? At a guess 20% or more of the probes I've been working with have failed within their first year of deployment. Sometimes they come back with a power cycle, sometimes they don't. Regards, Jon
