## Summary - Rename `date-modified` -> `modified` in all 80 docs and the `docs-check-frontmatter` task Quartz's `CreatedModifiedDate` plugin recognizes `modified`, `lastmod`, `updated`, and `last-modified` — but not `date-modified`. The wrong field name caused Quartz to ignore frontmatter dates entirely and fall through to filesystem timestamps (UTC inside Dagger), showing Feb 12 on pages built late on Feb 11 PST. ## Test plan - [x] `mise run docs-check-frontmatter` passes - [ ] Kick off docs release after merge — verify rendered dates match frontmatter values Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/158

# 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** | `grafana/alloy:v1.8.2` |
|
|
| **ArgoCD App** | `alloy-k8s` |
|
|
| **Fly.io Config** | `fly/alloy.river` |
|
|
| **Fly.io Image** | `grafana/alloy:v1.5.1` (binary copied into nginx container) |

## 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.
