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

Probe status / self-help
by Robert Kisteleki 20 Apr '16

20 Apr '16

Dear All, Today we released a new feature intended to help the probe hosts detecting, understanding and fixing various issued related to probes. You should be able to see a new "Status" tab on your probe page. This is where we explain various conditions, such as USB problems, non-working IPv6 or DNS resolutions quirks. Please note that this bit is in early stages (officially labeled as beta). We believe it works in general, however for now it only explains various system tags that mark error conditions. It will have more features in the future. It is also intended to be a place where we can add features that explain, for example, "your probe behaves differently than the rest" or "path MTU issues detected" or such. We think this will be a useful feature to hosts. Let us know if you have specific suggestions for improvement. Regards, Robert Kisteleki RIPE NCC

*-capable ≠ *-works + *-doesnt-work
by Bajpai, Vaibhav 20 Apr '16

Hello, I am looking at the probe API data for connected probes (status = 1) for day = 20160418 system-ipv6-capable = 3556 system-ipv6-works = 2995 system-ipv6-doesnt-work = 710 Why is system-ipv6-works + system-ipv6-doesnt-work > system-ipv6-capable? system-ipv4-capable = 9336 system-ipv4-works = 9187 system-ipv4-doesnt-work = 67 Why is system-ipv4-works + system-ipv4-doesnt-work < system-ipv4-capable?
