Nginx 1.25.0: experimental HTTP/3 support

Interesting! I’ve been using Caddy for a while and actually recently went back to Nginx just because I am now self hosting PeerTube and there was a config file for Nginx to proxy PeerTube server ready made.

But if Caddy can serve metrics which I can then collect with for example Grafana, that’s very interesting!

Yep, Caddy has metrics: https://caddyserver.com/docs/metrics

But caveat: we don't have maintainers who understand metrics currently, so it's nowhere near as good as we'd hope it to be. Help wanted!

Caddy's metrics have been disabled for like 9 months because they cause a massive performance penalty

HTTP metrics (and only HTTP metrics, not all metrics) were changed to being opt-in, support wasn't removed. See my docs link above. But yes, there are performance consideration we're not satisfied with, and we need help to get them resolved.

They're not disabled, just off-by-default for now.
