 ## Features
 
-- **System Overview**: Real-time monitoring of CPU, memory, temperature, and system uptime
+- **Host Backup & Restore** — integrated section covering Local, PBS and Borg destinations; schedule with a systemd timer or attach to an existing PVE vzdump job; PBS encryption with paired recovery blobs; direction-aware cross-kernel restore with kernel-agnostic hydration (IOMMU / VFIO / GRUB), cascade-safe package replay, and NIC auto-remap by MAC after a motherboard swap
-- **Storage Management**: Visual representation of storage distribution, disk health, and SMART data
+- **System Overview** — real-time CPU / memory / temperature / uptime with a per-process drill-down (Top Processes view) and click-through detail modal
-- **Network Monitoring**: Network interface statistics, real-time traffic graphs, and bandwidth usage
+- **Storage & SMART** — per-disk cards in a responsive grid; temperature history, SMART attributes and a downloadable PDF SMART report per drive. USB-NVMe bridges (ASMedia / JMicron / Realtek) show the real drive's identity and temperature instead of the enclosure's
-- **Virtual Machines & LXC**: Comprehensive view of all VMs and containers with resource usage and controls
+- **Network** — live topology (Network Flow) with animated rx / tx pulses, per-interface RRD charts, latency modal against Gateway / Cloudflare / Google with a downloadable PDF report
-- **Hardware Information**: Detailed hardware specifications including CPU, GPU, PCIe devices, and disks
+- **Virtual Machines & LXCs** — inventory, per-guest metrics and controls, per-LXC update inventory (apt / apk / community-scripts), backup state, mount inspection
-- **System Logs**: Real-time system log monitoring with filtering and search capabilities
+- **Hardware** — CPU / GPU / PCIe / disks / NICs, with correct SSD vs HDD classification even behind USB-SATA bridges
-- **Health Monitoring**: Proactive system health checks with persistent error tracking
+- **System Logs** — journalctl with severity / since / free-text filters and a download-as-text action
-- **Authentication & 2FA**: Optional password protection with TOTP-based two-factor authentication
+- **Health Monitor** — ten categories of proactive checks with hysteresis and configurable thresholds; per-error dismiss (24 h / 7 d / permanent) and an Active Suppressions panel to revoke
-- **RESTful API**: Complete API access for integrations with Homepage, Home Assistant, and custom dashboards
+- **Notifications** — five channels (Telegram, Discord, Gotify, Email, Apprise for ~80 endpoints), per-event toggles, Quiet Hours, Daily Digest, optional AI enrichment (Groq / OpenAI / Ollama / Gemini / Anthropic / OpenRouter)
-- **Dark/Light Theme**: Toggle between themes with Proxmox-inspired design
+- **Authentication & 2FA** — optional password protection with TOTP-based two-factor authentication and long-lived API tokens (365 days) for integrations
-- **Responsive Design**: Works seamlessly on desktop, tablet, and mobile devices
+- **RESTful API** — complete access with JWT auth; ready-made recipes for Homepage, Home Assistant and custom dashboards; Prometheus scrape endpoint
-- **Release Notes**: Automatic notifications of new features and improvements
+- **Reports (PDF)** — SMART report per-disk and Network Latency report per-target, ready to send to a vendor or an ISP
+- **Dark / Light Theme** — Proxmox-inspired palette with live switch
+- **Responsive Design** — desktop, tablet and mobile layouts
+- **Release Notes** — automatic notification of new features on each Monitor upgrade

+"""Sprint 14: per-disk temperature history.
+
+Mirrors the CPU ``temperature_history`` infrastructure in flask_server,
+but keyed by disk name so each physical drive gets its own time series.
+Same SQLite DB (``/usr/local/share/proxmenux/monitor.db``), same 30-day
+retention, same downsampling buckets the CPU history endpoint uses
+(hour=raw / day=5min / week=30min / month=2h).
+
+The sampler is a single function meant to be called once per minute
+from flask_server's existing ``_temperature_collector_loop``, so we
+don't add another background thread.
+
+Performance — three caches keep the steady-state cost flat on big JBODs:
+
+  * ``_disk_list_cache``    — lsblk + USB filter, refreshed every 5 min.
+  * ``_disk_probe_cache``   — remembers which ``smartctl -d <type>``
+                              variant works for each disk so we skip
+                              the 4-attempt fallback chain.
+  * ``_disk_fail_backoff``  — drives that never report a temperature
+                              are rate-limited to one re-probe per hour
+                              instead of every minute.
+
+The actual smartctl calls run in a ThreadPoolExecutor, so a 24-disk host
+spends ~max(per-disk time) per sample instead of sum.
