Knocks out the two daily recurring review tasks (doc review + service review) in one PR. ## Doc review (4 never-reviewed reference cards, `last-reviewed: 2026-06-04`) - **cluster.md** — Kubernetes version v1.34.0 → **v1.35.0**; refreshed the stale ringtail workload list and noted the in-progress minikube→k3s migration (points to `[[ringtail]]` as the canonical list). - **ntfy.md / tempo.md / alloy.md** — corrected image references: these are now **locally-built `registry.ops.eblu.me/blumeops/*` nix containers** (ntfy v2.19.2, tempo v2.10.3, alloy-k8s v1.16.0), not upstream Docker Hub. Fly.io alloy binary bumped to v1.16.1. ## Service review - **nvidia-device-plugin** (ringtail GPU): v0.19.0 → **v0.19.2**. Upstream patch releases — CDI/Tegra fixes + dependency bumps, no breaking changes for our manifest-based CDI + RuntimeClass setup (the service-account change in the notes is helm-only). ## Not in this PR (need container rebuilds, deferred) The other stale services are locally-built nix images, so upgrading them is a forge-runner rebuild rather than a clean tag bump — left untouched (not date-bumped, so they resurface): **prometheus** (v3.10.0→v3.12.0), **loki** (3.6.7→3.7.2), **kube-state-metrics**, **homepage**. Happy to do these as a follow-up rebuild PR. ## Deploy / verify Not yet deployed — `nvidia-device-plugin` still points at `main`. After review: ``` argocd app set nvidia-device-plugin --revision reviews-jun4 && argocd app sync nvidia-device-plugin # after merge: argocd app set nvidia-device-plugin --revision main && argocd app sync nvidia-device-plugin ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: #366

# Grafana Alloy
|
|
|
|
Unified observability collector for metrics and logs with three deployments:
|
|
1. **Indri (host)** - System metrics and service logs from macOS host
|
|
2. **Kubernetes (DaemonSet)** - Automatic pod log collection and service health probes
|
|
3. **Fly.io proxy (embedded)** - nginx access log metrics and log forwarding from [[flyio-proxy]]
|
|
|
|
## Quick Reference
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| **Indri Binary** | `~/.local/bin/alloy` |
|
|
| **Indri Config** | `~/.config/grafana-alloy/config.alloy` |
|
|
| **K8s Namespace** | `alloy` |
|
|
| **K8s Image** | `registry.ops.eblu.me/blumeops/alloy:v1.16.0-9564435` (locally built) |
|
|
| **ArgoCD App** | `alloy-k8s` |
|
|
| **Fly.io Config** | `fly/alloy.river` |
|
|
| **Fly.io Image** | `grafana/alloy:v1.16.1` (binary copied into nginx container, sha-pinned) |
|
|

|
## Metrics Collected
|
|
|
|
### From Indri
|
|
- System metrics via `prometheus.exporter.unix`
|
|
- Textfile collector: `minikube.prom`, `borgmatic.prom`, `zot.prom`, `jellyfin.prom`
|
|
- Zot registry metrics from `http://localhost:5050/metrics`
|
|
- Pushed to [[prometheus]] via remote_write
|
|
|
|
### From Kubernetes
|
|
- All pod logs via `loki.source.kubernetes`
|
|
- Service health probes: miniflux, kiwix, transmission, devpi, argocd
|
|
|
|
### From Fly.io Proxy
|
|
- `flyio_nginx_http_requests_total` — request rate by status/method/host
|
|
- `flyio_nginx_http_request_duration_seconds` — latency histogram
|
|
- `flyio_nginx_http_response_bytes_total` — response bandwidth
|
|
- `flyio_nginx_cache_requests_total` — cache HIT/MISS/EXPIRED counts
|
|
- Pushed to [[prometheus]] via remote_write through [[caddy]]
|
|
|
|
## Logs Collected
|
|
|
|
**Brew services:** forgejo, tailscale
|
|
|
|
**mcquack LaunchAgents:** alloy, borgmatic, zot, jellyfin
|
|
|
|
Logs pushed to [[loki]] at `https://loki.tail8d86e.ts.net/loki/api/v1/push`.
|
|
|
|
**Fly.io proxy:** nginx JSON access logs pushed to [[loki]] at `https://loki.ops.eblu.me/loki/api/v1/push` (via [[caddy]]).
|
|
|
|
## Why Built from Source
|
|
|
|
The Homebrew bottle uses `CGO_ENABLED=0`, which breaks Tailscale MagicDNS. Building with `CGO_ENABLED=1` uses the macOS native resolver.
|
|
|
|
**Note:** This may no longer be needed now that services use `*.ops.eblu.me` URLs (routed via Caddy) instead of `*.tail8d86e.ts.net`. Should be tested in the future.
