Each service gets its own Prometheus probe verifying actual functionality:
- API: /status endpoint (checks DB connectivity, returns 503 if down)
- Workers: /health endpoint (job server responsive)
- ERPNext: API method call (MariaDB + Redis + app all working)
- MinIO: /minio/health/live (storage accessible)
- Listmonk: /api/health (email service + DB)
- Ollama: root endpoint (LLM inference available)
- Umami: /api/heartbeat (analytics tracking)
- Forgejo: root page (git server accessible)
- PostgreSQL: pg_up metric from postgres-exporter
- All HTTPS endpoints: SSL + reachability from outside
Service-specific alerts with context:
- API down = DB may be unreachable
- Workers down = compliance orders not processing
- ERPNext down = CRM inaccessible
- MinIO down = document storage unavailable
Custom Grafana dashboard: "Performance West — Services Overview"
- Service status grid (UP/DOWN with colors)
- Response time charts (internal + HTTPS)
- SSL certificate expiry gauges
- Container CPU/memory per service
- PostgreSQL connections, nginx req/s, active alerts
