How can I spy on myself? (news.idlestate.org)

I'm curious to see what information I'm blasting out to the various services I depend on for internet (ISP, DNS, probably Cloudflare, etc.).

Are there any easy to setup, entirely self-hosted tools I can run on my home network that would allow me to snoop on my own traffic.

I want more than just DNS, so I'm not just looking for pihole and its ilk. I want to see things like SNI and any non-protected traffic that any of the devices on my network might be sending that I just don't know about.

Ideally, it would be something I could leave on without affecting my speed/latency, but something to turn on occasionally and spot check would be better than nothing.

My router runs VyOS, so I should have quite a bit of flexibility in what I do with my traffic, though I never have figured out if/how to deploy custom software to it...

Someone might suggest something more elegant but one solution is a trunk port, maybe on your router, maybe a downstream switch (assuming wireless Ap is downstream of all of those) and connect that to wireguard on your server?
