Raspi2 with dongles

SYNNACK and I were planning to bring 5x TP-Link Archer C7v2 with us which we've also used at 32C3 as WiFi-probes.

I'm not sure if you are referring to the same thing? :)

I was not, but all the better. Is Linux on them? What do they speak to read them out?

Ah :) this is a small project SYNNACK and I have been working on since December: https://github.com/bitlair/wifi-probe - and that is also one of the reasons why we wanted to help out at FOSDEM. The project is however in a very early state :)

So they run OpenWRT, wpa_supplicant and some scripts for automated tests. You would deploy a probe in a large room where it can hear multiple accesspoints. The probe will sequently connect to accesspoints it can hear and report metrics to Graphite/Carbon.

Reporting for now happens over the wired interface of the Archer C7v2; testing happens over wlan0 & wlan1 which have their own routing tables.

We went with Graphite/Carbon for this project since it lined up with the WiFi infrastructure monitoring of 32C3/CCC. That way we can compare metrics from the probes and WiFi infrastructure easily.

If needed we can bring a server with us (along with the Archer C7v2's) for Graphite/Carbon and HTTP server to test against (but this could also easily run on a VM).

Just to confirm: SYNNACK and I will bring: 5x Archer C7v2 as WiFi-probes and a Sun server that runs Debian with KVM and a Graphite VM.

Wired connectivity for the probes has been discussed with Wouter.

Ah, nice. I have 5 RPi2s with wifi adapters. If we can get WRT to run on the Pis, we can add them to your Archers.

We can plumb that into Prometheus presuming you're using the plaintext graphite protocol. http://www.robustperception.io/replacing-graphite-with-prometheus/

4 WiFi-probes are up:

probe01: Janson probe02: La Fontaine (K building) probe03: H building probe04: AW building

Reporting for now happens to Graphite at http://151.216.191.250/
