So I’ve got a home server that’s having issues with services flapping and I’m trying to figure out what toolchain would be actually useful for telling me why it’s happening, and not just when it happened.

Using UptimeKuma, and it’s happy enough to tell me that it couldn’t connect or a 503 happened or whatever, but that’s kinda useless because the service is essentially immediately working by the time I get the notice.

What tooling would be a little more detailed in to the why, so I can determine the fault and fix it?

I’m not sure if it’s the ISP, something in my networking configuration, something on the home server, a bad cable, or whatever because I see nothing in logs related to the application or the underlying host that would indicate anything even happened.

It’s also not EVERY service on the server at once, but rather just one or two while the other pile doesn’t alert.

In sort: it’s annoying and I’m not really making headway for something that can do a better job at root-cause-ing what’s going on.
