## Migrated Services
- **PhotoPrism** and **Immich** were migrated to VM113 (photos, 192.168.88.32) in April 2026
- See `/home/jgitta/Documents/Claude/Projects/Photos/photos.md` for current details
## Photo Management
- **Immich** runs on VM113 (photos, 192.168.88.32) — migrated from siklos in April 2026
- **PhotoPrism** was removed from siklos in June 2026 — Immich chosen as the single photo management solution

## Monitoring Stack — Beszel (migrated 2026-06-18)
Replaced Prometheus + Grafana + cAdvisor + node_exporter with **Beszel** — a lightweight all-in-one monitoring tool.
- **Hub**: Docker container on siklos, port 8085 → `https://beszel.jgitta.com`
- **Compose**: `/srv/docker/beszel/docker-compose.yml`
- **Architecture**: Hub communicates with agents over SSH (port 45876). On siklos the agent uses a unix socket (`/srv/docker/beszel/beszel_socket/beszel.sock`) to avoid Docker network isolation issues.
- **Agent deployment**: Binary + systemd service (`beszel-agent.service`) on each remote host. Install script: `curl -sL https://get.beszel.dev/agent | bash`
- **Universal token**: Used to auto-register agents — stored in PocketBase `universal_tokens` collection
- **Agents installed on**: siklos (.27), jellyfin (.10), thinkstation (.41), proxmox jg-hud (.25), PBS (.60), caddy (.110), photos VM113 (.32), OCIS VM114 (.63)
- **Alerts configured** (via PocketBase API, regular user token required — not superuser):
- `Status` — host goes down
- `CPU` — >90%
- `Memory` — >90%
- `Disk` — >85%
- **Notifications**: Telegram bot `8758434542:AAEW6omM7twyInsb2INuy6mD1w2EWXHqmzE`, chat `8260387200`
- **Uptime Kuma**: port 3001 (`status.jgitta.com`), joined to `pihole_default` network — handles HTTP/port/DNS uptime checks (separate from Beszel resource monitoring)

## Key Notes
- Watchtower excludes Pi-hole from auto-updates
- NFS mount `/mnt/photos` was removed from Siklos `/etc/fstab` after PhotoPrism/Immich migration
- OnlyOffice replaced Collabora (lighter RAM usage)
- RAM reduced from 16GB → 12GB (April 2026, live via Proxmox balloon driver, no reboot)
- `vm.swappiness=10` set to reduce swap pressure after photo services migrated out
- OnlyOffice replaced Collabora (lighter RAM usage)
- RAM reduced from 16GB → 12GB (April 2026, live via Proxmox balloon driver, no reboot) — freed further in June 2026 when PhotoPrism was removed
- `vm.swappiness=10` set to reduce swap pressure
- NFS mount `/mnt/immich-photos` (from VM113 192.168.88.32) is in fstab — read-only access to Immich photo storage
