## Summary
- Add `smartctl_exporter` Docker container to sifaka for SMART disk health monitoring
- Formalize existing `node_exporter` container under Ansible management
- Route both exporters through Caddy L4 TCP proxy (`nas.ops.eblu.me:9100`, `nas.ops.eblu.me:9633`), replacing the hardcoded LAN IP in Prometheus
- Create "Sifaka Disk Health" Grafana dashboard (health status, temperature, wear indicators, lifetime)
- Introduce `ansible/playbooks/sifaka.yml` and `mise run provision-sifaka` — first Ansible playbook for the NAS
- Shared exporter port variables in `group_vars/all.yml` to avoid duplication between Caddy and sifaka roles
## Prerequisites before deploy
- [ ] Enable SSH on sifaka (DSM Control Panel > Terminal & SNMP)
- [ ] Verify `ssh eblume@sifaka 'docker ps'` works
- [ ] Run `mise run provision-sifaka` to deploy containers
- [ ] Run `mise run provision-indri -- --tags caddy` to add L4 routes
- [ ] `argocd app sync prometheus` + `argocd app sync grafana-config`
## Test plan
- [ ] Verify smartctl_exporter metrics: `curl http://nas.ops.eblu.me:9633/metrics`
- [ ] Verify Prometheus targets page shows both sifaka jobs as UP
- [ ] Verify Grafana "Sifaka Disk Health" dashboard loads with data

## 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
- Add "Unhealthy Pods" stat panel showing count of pods in error states (ImagePullBackOff, CrashLoopBackOff, etc.) with red background when > 0
- Add "Pods by Waiting Reason" time series chart showing container waiting states over time
- Provides visibility into stuck pods that ArgoCD doesn't track (since it manages CronJobs, not the Jobs/Pods they spawn)
## Context
This addresses the issue where a `zim-watcher` cronjob pod was stuck in `ImagePullBackOff` for 11 days without any alerting. ArgoCD showed the CronJob as "Synced, Healthy" because it only manages the CronJob resource, not its spawned Jobs/Pods.
## Deployment and Testing
- [ ] Sync grafana-config app to test branch
- [ ] Verify dashboard renders correctly
- [ ] Confirm "Unhealthy Pods" shows 0 (green) when no issues
- [ ] Reset to main after merge

## Summary
- Add fixed Y-axis (0-220M) so the 200M autovacuum threshold is always visible
- Add dashed threshold lines at 150M (yellow warning) and 200M (red danger)
- Update title to clarify the threshold
## Context
The raw XID age naturally trends upward between vacuum freezes, which looked alarming without context. Current values (~143K-216K) are at 0.1% of the threshold - completely healthy.
## Deployment and Testing
- [ ] Sync grafana-config app to feature branch
- [ ] Verify threshold lines appear on PostgreSQL dashboard

Note: the name of this branch was chosen before the scope widened to encompass the entire observability stack.
Summary
- Fix Grafana data source URLs (docker driver uses host.minikube.internal, not host.containers.internal)
- Migrate Prometheus and Loki from indri to Kubernetes with Tailscale Ingresses
- Expose CNPG PostgreSQL metrics via Tailscale and update dashboard to use cnpg_* metrics
- Update Alloy to push metrics/logs to k8s endpoints (prometheus.tail8d86e.ts.net, loki.tail8d86e.ts.net)
- Add ACL rule for port 9187 (CNPG metrics)
- Delete obsolete ansible roles for prometheus and loki
Changes
- argocd/manifests/prometheus/ - New Prometheus StatefulSet with 20Gi PVC and Tailscale Ingress
- argocd/manifests/loki/ - New Loki StatefulSet with 20Gi PVC and Tailscale Ingress
- argocd/apps/prometheus.yaml, argocd/apps/loki.yaml - ArgoCD Applications
- argocd/manifests/grafana/values.yaml - Data sources now use k8s internal DNS
- argocd/manifests/databases/service-metrics-tailscale.yaml - CNPG metrics endpoint
- argocd/manifests/grafana-config/dashboards/configmap-postgresql.yaml - Updated to cnpg_* metrics
- ansible/roles/alloy/defaults/main.yml - Push to k8s Tailscale endpoints
- pulumi/policy.hujson - ACL for port 9187

- Run mise run provision-indri -- --tags alloy
- Verify Grafana dashboards show data
