# Grafana Alloy

Unified observability collector for metrics and logs with two deployments:
1. **Indri (host)** - System metrics and service logs from macOS host
2. **Kubernetes (DaemonSet)** - Automatic pod log collection and service health probes

## 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` |

## 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

## 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`.

## 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.
