To me this looks like a Doctor Who episode. We have the Dalec and the Tardis in the scene 😂

Yeah better fit but a bit of trouble to setup… What’s your opinion on Icinga? Never used it myself.

Give https://github.com/louislam/uptime-kuma a try. I’m planning to do the same for similar use case. Sensu (sensu.io) is a more sophisticated option but it requires more infrastructure and there is a bit of a learning curve with it.
