upsert_event now returns ticket_id (4th element) so callers can skip
ticket creation when one already exists. This prevents calling the ticket
API every poll cycle for ongoing issues while still retrying if the
previous creation attempt failed (ticket_id stays NULL until success).
Cluster events use (is_new or not ticket_id) so they too get retried
on failure rather than relying solely on is_new.

datetime.utcnow() is deprecated in Python 3.12 and removed in 3.13.
Replace all four call sites with timezone-aware equivalents so the
codebase is ready for Python 3.12+.

db.py returned all datetime columns (first_seen, last_seen, resolved_at,
created_at, expires_at) as bare ISO strings like "2026-03-14T14:14:21"
with no timezone marker. Per the ECMAScript spec, new Date() on a
datetime string without timezone treats it as LOCAL time, not UTC.
This made lt.time.ago() and stale-detection wrong for any user whose
browser is not in UTC — event ages and stale warnings would be off by
the client's UTC offset.
monitor.py had the same issue on the network_snapshot 'updated' field.
Fix: append 'Z' to all isoformat() calls (UTC datetimes confirmed by
MySQL server timezone and _now_utc() pattern used throughout codebase).

- inspector.html: fix LLDP neighbor label in port blocks — port.lldp_table never exists; data is at port.lldp (dict with system_name/chassis_id); both port block renderers corrected
- db.py: remove dead 'target_detail IS NULL' branch in suppression check — target_detail is always stored as '' not NULL; query simplified to target_detail=''
- app.py: resolve cache_dir/cache_file/sentinel to absolute paths; guard against path escape before use
- app.py: wrap sentinel os.path.getmtime() in try/except OSError to handle TOCTOU deletion race

- db.py: add resolved_24h to get_status_summary() so each /api/status
poll carries the fresh 24h resolved count
- app.js: wire stat-resolved-val to update from summary.resolved_24h
so the Resolved 24h card stays accurate after auto-refresh
- index.html: add lt-toolbar/lt-search above host grid for quick
client-side host filtering by name
- links.html: replace custom unifi-section-header div with lt-divider
- style.css: remove unused .unifi-section-header rules

- 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
