- get_active_events() now takes limit/offset (default 200) to cap unbounded queries
- count_active_events() added to return total for pagination display
- /api/events supports ?limit=, ?offset=, ?status= query params (max 1000)
- /api/status includes total_active count alongside paginated events list
- index() route passes total_active to template for server-side truncation notice
- Show "Showing X of Y" notice in dashboard when events are truncated
- Suppression POST validates: reason ≤500 chars, target_name/detail ≤255 chars
- _purge_old_jobs_loop runs purge_old_resolved_events(90d) once per day

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

db.py:
- Add check_suppressed(suppressions, ...) for in-memory suppression lookups
against pre-loaded list (eliminates N*M DB queries per monitoring cycle)
- get_baseline(): log error instead of silently swallowing JSON parse failure
monitor.py:
- Load active suppressions once per cycle at the top of the alert loop
- Pass suppressions list to _process_interfaces, _process_unifi, _process_ping_hosts
- Replace all db.is_suppressed() calls with db.check_suppressed(suppressions, ...)
- Reduces DB queries from 100-600+ per cycle down to 1

- 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
