- dashboard: pass recent_resolved (last 24h, limit 10) to index template;
render "Recently Resolved" section showing type, target, resolved time,
and calculated duration (first_seen → resolved_at)
- dashboard: event-age spans now also update via setInterval; duration
shown for resolved events (e.g. "2h 15m")
- links page: link health summary panel shows server iface count,
error/flap counts, switch port up/down, PoE total draw/capacity bar;
only shows problematic stats if non-zero; shows "All OK ✔" when clean
- style.css: new classes for summary panel, resolved row/badge

- events table: add Last Seen column; show relative times ("3h ago") with
absolute timestamp on hover; update updateEventsTable() in app.js to match
- links.html: add error/drop/flap alert badges to interface and port card headers
- links.html: PoE power bar (draw/max ratio with colour-coded fill) and poe_mode
- links.html: stale data warning banner when link_stats are >2 minutes old
- links.html: improved error handler shows HTTP status instead of generic message
- links.html: fix collapse state persisted to localStorage (was sessionStorage,
lost on browser restart); fix collapseAll/expandAll to also persist state
- inspector.html: duplex mismatch and speed mismatch warnings in path debug panel
- inspector.html: carrier changes added to server column of path debug
- style.css: new classes — .link-alert-badge, .poe-bar-*, .path-mismatch-alert,
.error-state; fix .stale-banner to use CSS variables

static/app.js:
- Browser tab title updates to show alert count: '(3 CRIT) GANDALF' or '(2 WARN) GANDALF'
- Stale monitoring banner: injected into .main if last_check > 15 min old,
warns operator that the monitor daemon may be down
static/style.css:
- .stale-banner: amber top-border warning strip
app.py:
- /health now checks DB connectivity and monitor freshness (last_check age)
Returns 503 + degraded status if DB unreachable or monitor stale >20min
db.py:
- cleanup_expired_suppressions(): marks time-limited suppressions inactive when
expires_at <= NOW() (was only filtered in SELECTs, never marked inactive)
- purge_old_resolved_events(days=90): deletes old resolved events to prevent
unbounded table growth
monitor.py:
- Calls cleanup_expired_suppressions() and purge_old_resolved_events() each cycle

Adds comprehensive per-port link troubleshooting triggered from the
Inspector panel when a port has an LLDP-identified server counterpart.
- diagnose.py: DiagnosticsRunner with 15-section SSH command (carrier,
operstate, sysfs counters, ethtool, ethtool -i/-a/-g/-S/-m, ip link,
ip addr, ip route, dmesg, lldpctl); parsers for all sections; health
analyzer with 14 check codes (NO_CARRIER, HALF_DUPLEX, SPEED_MISMATCH,
SFP_RX_CRITICAL, CARRIER_FLAPPING, CRC_ERRORS_HIGH, LLDP_MISMATCH, etc.)
- monitor.py: PulseClient now tracks last_execution_id so callers can
link back to the raw Pulse execution URL
- app.py: POST /api/diagnose + GET /api/diagnose/<job_id> with daemon
thread background execution and 10-minute in-memory job store
- inspector.html: "Run Link Diagnostics" button (shown only when LLDP
host is resolvable); full results panel: health banner, physical layer,
SFP/DOM with power bars, NIC error counters, collapsible ethtool -S,
flow control/ring buffers, driver info, LLDP 2-col validation,
collapsible dmesg, switch port summary, "View in Pulse" link
- style.css: all .diag-* CSS classes with terminal aesthetic

- 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
