## Summary
- Remove `match_all = true` from `flyio_nginx_cache_requests_total` in Alloy so the metric only counts requests that go through the proxy cache (excludes health checks with empty `cache_status`)
- Change dashboard queries from `rate(...[5m])` to `increase(...[$__range])` — aggregates over the full dashboard time window instead of a 5-minute sliding window, giving meaningful ratios for low-traffic static sites
- Add null/NaN value mapping to show "No traffic" in neutral color instead of blank/red
## Root cause
Health check requests from Fly.io hit the default nginx server block (no `proxy_cache`), producing entries with empty `upstream_cache_status`. With `match_all = true`, these were counted in the cache metric, diluting the Fly.io dashboard ratio. For APM dashboards, `rate()[5m]` on low-traffic sites with 24h cache validity almost always returns either all-HITs (100%) or no data (blank → red background).
## Deployment
- Fly.io proxy redeploy needed for Alloy config change
- ArgoCD sync for dashboard ConfigMap changes
## Test plan
- [ ] Redeploy Fly.io proxy
- [ ] Sync grafana-config in ArgoCD
- [ ] Verify CV APM cache hit ratio shows a real percentage (not 100%)
- [ ] Verify Docs APM shows "No traffic" in neutral color when idle, real ratio when visited
- [ ] Verify Fly.io proxy dashboard cache ratio excludes health checks

## Summary
- Add `client_ip` field to the Fly.io nginx JSON log format, sourced from `Fly-Client-IP` header
- Extract `client_ip` in the Alloy pipeline so it's available as a parsed field in Loki
- Keeps `remote_addr` (the internal proxy IP) for debugging
Fixes: Grafana access logs for docs.eblu.me showing 172.16.11.178 for every request instead of real visitor IPs.
## Deployment and Testing
- [ ] Deploy updated fly.io proxy: `fly deploy` from `fly/` directory
- [ ] Verify in Grafana that new log lines include `client_ip` with real IPs
- [ ] Confirm `remote_addr` still shows the proxy IP (preserved for debugging)

## Summary
- Introduce `tag:flyio-target` so services must explicitly opt in to be reachable by the fly.io proxy
- Replace broad `tag:k8s` and `tag:homelab` grants with the new tag in the ACL rule and test
- Add `tailscale.com/tags: "tag:k8s,tag:flyio-target"` annotation to docs, loki, and prometheus Ingresses
- Switch Alloy push endpoints from `*.ops.eblu.me` (Caddy) to `*.tail8d86e.ts.net` (Tailscale Ingress)
- Update docs: flyio-proxy, caddy, tailscale, forgejo (future public access + security checklist), expose-service-publicly
## Manual step (not in PR)
Update the k8s operator OAuth client in the Tailscale admin console to include `tag:flyio-target` in its scope. Without this, the operator cannot assign the new tag to Ingress proxy nodes.
## Deployment order
1. **Pulumi ACLs** — `mise run tailnet-preview && mise run tailnet-up`
2. **OAuth client** — Manual update in Tailscale admin console
3. **K8s Ingresses** — `argocd app sync apps && argocd app sync docs loki prometheus`
4. **Fly.io proxy** — `mise run fly-deploy`
5. **Verify** — `mise run services-check`, check Grafana dashboards
## Test plan
- [ ] `mise run tailnet-preview` shows clean diff
- [ ] `argocd app diff docs`, `argocd app diff loki`, `argocd app diff prometheus` show only annotation additions
- [ ] After deploy: Grafana dashboards show continued log/metric flow
- [ ] `curl -sf https://docs.eblu.me` returns 200
- [ ] `mise run services-check` passes
