Summary

Implements complete observability stack covering Metrics / Logs / Traces / Alerting / Uptime monitoring.

Fixes #10

Services Implemented

Service Image Purpose
Prometheus prom/prometheus:v2.54.1 Metrics collection
Grafana grafana/grafana:11.2.2 Visualization & dashboards
Loki grafana/loki:3.2.0 Log aggregation
Promtail grafana/promtail:3.2.0 Log collection agent
Tempo grafana/tempo:2.6.0 Distributed tracing
Alertmanager prom/alertmanager:v0.27.0 Alert routing
cAdvisor gcr.io/cadvisor/cadvisor:v0.50.0 Container metrics
Node Exporter prom/node-exporter:v1.8.2 Host metrics
Uptime Kuma louislam/uptime-kuma:1.23.15 Service availability

Core Requirements Checklist

1. Prometheus Scrape Targets

  • prometheus (self-monitoring)
  • node-exporter (host metrics)
  • cadvisor (container metrics)
  • traefik (reverse proxy)
  • authentik (SSO)
  • nextcloud (storage)
  • gitea (git hosting)
  • loki, tempo, ntfy

2. Grafana Provisioned Dashboards

All dashboards auto-load from config/grafana/dashboards/:

  • Node Exporter Full (host metrics)
  • Docker Container Metrics
  • Traefik Official
  • Loki Logs Explorer
  • Uptime Kuma

3. Alert Rules

config/prometheus/rules/ contains:

  • host.yml: CPU > 80%, Memory > 90%, Disk > 85%, Disk IO
  • containers.yml: Restart > 3/hour, OOM, Health check failures
  • services.yml: Traefik 5xx > 1%, Response P99 > 2s

4. Loki Log Collection

Promtail collects:

  • All Docker container logs (auto-discovery)
  • System logs
  • Traefik access logs with trace ID extraction

5. Uptime Kuma

  • Service at status.${DOMAIN}
  • Setup script: scripts/uptime-kuma-setup.sh
  • Public status page

6. Grafana SSO

  • Authentik OIDC integration
  • homelab-admins group = Admin role
  • homelab-users group = Viewer role

7. Data Retention

  • PROMETHEUS_RETENTION=30d
  • LOKI_RETENTION=168h (7 days)
  • TEMPO_RETENTION=72h (3 days)

Testing

  1. Start monitoring: ./scripts/stack-manager.sh start monitoring
  2. Verify Prometheus targets: curl localhost:9090/api/v1/targets
  3. Access Grafana dashboards
  4. Test alerts: stress --cpu 4 --timeout 300
  5. Setup Uptime Kuma: ./scripts/uptime-kuma-setup.sh
