- storage-01 now monitored via Prometheus node_exporter (10.10.10.11:9100),
removed from ping_hosts
- Updated data sources table (6 hosts via Prometheus, pbs only via ping)
- Added storage-01 to monitored hosts table
- Fixed Authelia reload command (restart, not reload)

- Two-service architecture: Flask web app (gandalf.service) + background
polling daemon (gandalf-monitor.service)
- Monitor polls Prometheus node_network_up for physical NIC states on all
6 hypervisors (added storage-01 at 10.10.10.11:9100)
- UniFi API monitoring for switches, APs, and gateway device status
- Ping reachability for hosts without node_exporter (pbs only now)
- Smart baseline: interfaces first seen as down are never alerted on;
only UP→DOWN regressions trigger tickets
- Cluster-wide P1 ticket when 3+ hosts have genuine simultaneous
interface regressions (guards against false positives on startup)
- Tinker Tickets integration with 24-hour hash-based deduplication
- Alert suppression: manual toggle or timed windows (30m/1h/4h/8h)
- Authelia SSO via forward-auth headers, admin group required
- Network topology: Internet → UDM-Pro → Agg Switch (10G DAC) →
PoE Switch (10G DAC) → Hosts
- MariaDB schema, suppression management UI, host/interface cards
