Nice write up, but there's just going to be a LOT of false positives.

False positive what? I didn't give any specific examples of alerts, just simply monitoring metrics. Are you referring to the note on the Dnsmasq memory leak?

I used to be into Ham radio when I was a younger man. I took a course from NRI I saw in an old popular science mag. Built a 5 watt receiver and xmitter, code only. On a good night with good ionosphere coverage, I could bounce that 5 watts half way around the world. I would have never have imagined communication technologies as we enjoy today.

Love to hear things like that! When I first got licensed the solar cycle was utter trash. We're past the peak now, but band conditions are still pretty good generally. A few watts and a wire will still get you somewhere with CW and some other forward error corrected modes (like FT8). I have a lot of fun with the digital stuff like AREDN, but it's definitely a different ball game and the old school SSB-based radio still has its place in my heart.

Wow...memories come flooding back.
The ionosphere depletion really made an impression on me as a young man. In conjunction with my ham radio, I used to point a telescope at the sun that had a special lens on it to keep you from burning a hole in your head. Then I would turn the eyepiece 180 deg, put a regular lens in and point it onto a white piece of cardboard. You could watch the solar flares and track them across the sun as very dark shadowy spots on the cardboard. When there weren't a lot of solar flare activity, signals went farther on the bounce. In my memory it was probably the last time that we as a global community banded together to solve the issue of ionosphere depletion because of aerosols.
Many many nights of QSL CQ! CQ!. I still have a trunk full of old QSL cards. Do they still do that now days?

For any hams here, maybe this blog post will be up your alley. 73!
