Upkeep
Kept seen, kept safe, kept running — observability, backups, the outside watchdog, and the automation that wires it all together.
In a nutshell
Upkeep is the layer that watches the others and keeps them alive. None of it is a service a member opens; it is the machinery that notices when something breaks, preserves what must survive, and quietly moves data between services so the rest can do their jobs.
The observability tools — Grafana, Wazuh, Loki, and Matomo — see the enclave from within; Proxmox Backup Server keeps what’s durable; Uptime Kuma watches from outside; and n8n is the glue, the automation that provisions, writes back, and broadcasts across the enclave. The watching topology that ties the observability tools together lives in Systems (watch).
