Connection Test Exporter

A quick utility I wrote to test my internet connection, and record a log of when it was up or down.

*** Now with prometheus metrics support! ***

By default it attempts to connect by default to bbc.co.uk, and will export a number of metrics to prometheus as it does so, along with writing out some cool output to your terminal. It can also write a log to a directory in your home folder. It should work on all platforms supported by the go compiler, but has only been tested on Windows 10 for now, as that's the PC I have that's connected by ethernet directly to my home router.

Build

go build

Requires

Some kind of emoji font installed because I like being able to spot the dropped connections at a glance in the output.

FAQs

Why not just use the blackbox exporter?

Good question - because I wanted to write something myself.
