name: nas-dashboard description: >- 🏠 NAS Dashboard v3 — 环境感知的智能运维仪表盘。

适合谁：自建 NAS / HomeLab / 家庭服务器用户，跑了 ZFS + Docker + 一堆自托管服务，需要一个"一眼看清问题、告诉你修什么"的每日健康报告。

做什么：一键采集系统全貌（ZFS/磁盘SMART/Docker/Frigate摄像头/GPU/UPS/安全审计），环境感知评估（内网/公网分级），三级严重度（🔴紧急🟡关注🟢参考），每条告警附带评估原因+可执行修复命令。

最佳环境：Ubuntu/Debian + ZFS + Docker，有 UPS 和 Frigate NVR 效果最佳。支持 Telegram 每日推送。

一句话：不用天天盯着服务器，每天早上看一眼有没有🔴，有就照着修。

Triggers: "nas status", "server status", "system dashboard", "文本仪表盘", "服务器状态", "系统健康".

NAS Dashboard v3#

Exception-driven, alert-first text dashboard for NAS/HomeLab monitoring. Prioritises problems over green lights — if everything is healthy you get a one-liner, if something is wrong you get a surgical report with severity ratings and actionable fix commands.

Platform: Linux (Ubuntu/Debian tested). Partial support: any Linux with ZFS. macOS/Windows: most sections unavailable (ZFS, SMART, systemd, apt, iostat, sensors are Linux-only).

Design Principles#

1. Alerts First: ❌/⚠️ always on top. No alerts → no ALERTS section.
2. Normal is Invisible: Don't list 15 healthy containers. Collapse to "X running (Y OK)".
3. Contextual Correlation: Disk ↔ ZFS vdev, container unhealthy + CPU process = zombie.
4. Actionable Thresholds: Timeshift >100 warns, SMART realloc>0 alarms, disk>45°C flags.
5. Unified Timestamps: All times in YYYY-MM-DD HH:MM or XdXh relative.

Quick Start#

Configure (optional)#

bash

export ZPOOL="tank"              # default: auto-detect first pool
export DISK_LIST="sda sdb sdc"   # default: auto-detect all /dev/sd?
export FRIGATE_CAM_MAP="cam_d82e8e00:客厅,cam_ae7e3010:门口,cam_a24a20c0:车库"
export UPS_NAME="ups@localhost"  # default: ups@localhost

Run#

bash

bash scripts/collect.sh

Cron setup#

bash

openclaw cron add \
  --name "NAS仪表盘" \
  --schedule "0 9 * * *" \
  --agent main \
  --timeout 180 \
  --delivery "announce:telegram:YOUR_CHAT_ID" \
  --prompt "Run nas-dashboard skill: collect and format the dashboard report, then send to Telegram."

Workflow#

1. Collect data#

Run scripts/collect.sh. Sections: SYSTEM, ZFS, VDEV_DISK (disk→pool mapping), DISKS (incl. SMART realloc/pending/udma), DISKIO, DOCKER, FRIGATE, GPU, NETWORK, PROCESSES, SERVICES, LOGS, SHARES, SECURITY, UPDATES, BOOT, UPS, TIMESHIFT.

2. Format output — Alert-First Layout#

Step 0: Scan for Alerts (always do this first)

Scan ALL collected data against these thresholds and classify severity:

ScopeConditionSeverityPool health ≠ ONLINEany pool❌ CRITICALScrub errors > 0any pool❌ CRITICALZFS_EVENT presentany event⚠️ WARNINGDisk health ≠ PASSEDany disk❌ CRITICALDisk realloc > 0any disk❌ CRITICALDisk pending > 0any disk⚠️ WARNINGDisk udma_crc > 100any disk⚠️ WARNINGDisk temp > 45°Cany disk⚠️ WARNINGDisk temp > 55°Cany disk❌ CRITICALDisk r_await > 20ms or w_await > 20msany disk⚠️ WARNINGDocker container Down/Unhealthyany ctr⚠️ WARNINGFrigate camera skip > 1.0any camera⚠️ WARNINGFrigate camera fps = 0any camera❌ CRITICALFrigate storage > 80%any storage⚠️ WARNINGFrigate storage > 95%any storage❌ CRITICALTimeshift count > 100ts active⚠️ WARNINGTimeshift count > 300ts active❌ CRITICALCPU temp > 70°C⚠️ WARNINGCPU temp > 85°C❌ CRITICALGPU temp > 75°C⚠️ WARNINGGPU temp > 85°C❌ CRITICALARC hit rate < 90%⚠️ WARNINGZFS capacity > 80%⚠️ WARNINGZFS capacity > 90%❌ CRITICALRoot disk > 85%⚠️ WARNINGRoot disk > 95%❌ CRITICALFailed logins > 0today⚠️ WARNINGFailed systemd servicesany⚠️ WARNINGUPS ≠ OL (not Online)⚠️ WARNINGUPS battery < 50%⚠️ WARNINGOOM events present⚠️ WARNINGSSH pass auth onsshd⚠️ WARNINGSSH root login onsshd⚠️ WARNINGFirewall inactiveufw/iptables⚠️ WARNINGContainer image >6moDockerℹ️ INFOAPT updates availableℹ️ INFO

If 0 alerts: skip the 🚨 风险预警 section entirely.

If alerts exist: build 🚨 风险预警 section listing every alert, grouped by severity (❌ first, then ⚠️, then ℹ️). Format:

text

🚨 风险预警
❌ {description}
⚠️ {description}

Step 1: Build ALERTS Section (if any)

Sort by severity: ❌ CRITICAL → ⚠️ WARNING → ℹ️ INFO. One line per alert. Examples:

• ❌ sde (tank) Reallocated_Sector_Ct: 5 — 坏道增长，建议立即更换
• ⚠️ cam_a24a20c0 skip:2.4 — 解码丢帧，检查 GPU 或降低分辨率
• ⚠️ nextcloud (Docker) unhealthy — 容器异常
• ⚠️ nfs-server (service) inactive — NFS 服务未运行
• ⚠️ Timeshift: 430 snaps — 过多，建议清理 (>100)
• ⚠️ sde udma_crc:29 — SATA 链路错误
• ℹ️ 0 APT updates pending

Correlation rules (apply these when building alerts):

• If a Docker container is unhealthy AND a process with the same name has >1% CPU → append (疑似僵死进程，建议重启容器)
• If a Frigate camera has skip>1.0 AND GPU utilization is high → append (GPU 编码瓶颈)
• If a disk has udma>0 → mention potential SATA cable issue

Step 2: Build Dashboard Body

Use this compact layout. Omit sections entirely if no data or all is healthy and not noteworthy.

text

╭──────────────────────────────────╮
│  🏠 NAS Dashboard · {YYYY-MM-DD (周X)}  │
╰──────────────────────────────────╯

Then sections in order:

🖥 SYSTEM — one line:

text

🖥 {hostname} · {OS_short} · up {uptime_simplified} · load:{load_1min}
   CPU:{cpu_used%} ██████░░░░ · RAM:{mem_used}/{mem_total} ({mem_pct}) · / {root_used}/{root_total} ({root_pct})
   CPU:{cpu_temp°C} · Mobo:{hottest_mobo_temp}°C

• uptime_simplified: convert "1 week, 2 days, 18 hours" → "1w2d18h"
• OS_short: "Ubuntu 24.04" from "Ubuntu 24.04.4 LTS"
• Only show the single highest mobo temp (not all sensors)
• CPU progress bar: 10 chars, cpu_used/10 → █ count

🗄 ZFS — pool summary line + ARC line:

text

🗄 {pool} [{health_emoji} {health}] · {alloc}T/{size}T ({cap}%) ██████░░░░ · frag:{frag}%
   ARC:{arc_size}GiB/{arc_max}GiB · hit:{arc_hit}% · Scrub:{scrub_summary}

• Scrub summary: extract "repaired 0B, 0 errors" and date from SCRUB field
• If L2ARC size > 0: append · L2ARC:{l2_size}GiB hit:{l2_hit}%
• ZFS capacity bar: cap/10 → █ count
• If ARC hit < 90%: add ⚠️ prefix
• Snapshots: Snaps:{count} latest:{yyyy-mm-dd}

💾 DISKS — fixed-width column layout, one line per disk.

Use a mini-table with │ separators so all status emoji align vertically:

text

💾 DISKS ───────────────────────────────────
sda (tank) │ W1003ABYZ-011FA0 │  931G │ 42°C │ 10909h │              ✅
sdc (tank) │ WD10PURX-78D85Y0 │  931G │ 39°C │  6804h │ r_await:10ms ✅
sde (tank) │ ST1000DM003-1ER16 │  931G │ 36°C │ 10223h │  udma:29     ✅

Column widths (pad/crop each field to fit):

ColFieldWidthAlign1{disk} ({pool_role})9left2model name18left, truncate if longer3size6right4temp5right5hours7right6alerts + status14right

• Col 6 (alerts + status): padding is dynamic but right-aligned. Contents:
  • realloc:X if > 0 (else pad)
  • pending:X if > 0 (else pad)
  • udma:X if > 0 (else pad)
  • r_await:Xms if > 5ms (else pad)
  • Always end with ✅ (PASSED) or ❌ (FAIL)
• Use VDEV_DISK data to annotate pool role: sda (tank), sdb (tank-cache) etc.
• Model: use full model string, crop to 18 chars if longer
• ⚠️ prefix the whole line if temp>45°C or realloc>0 or pending>0 or udma>100
• Serial is omitted (model provides enough identification for this view)

Disk I/O — only show disks with util>5% or await>10ms:

text

   IO: sda r2.5/w4.6ms util5.2% · sdc r10.5/w3.3ms

🐳 DOCKER — converged view:

text

🐳 {total} running ({healthy_count} healthy) · v{docker_ver} · {image_count} imgs · {volume_gb}GB

Then only list unhealthy containers explicitly:

text

   ⚠️ nextcloud: Up 2 days (no healthcheck)
   ℹ️ vaultwarden/server:latest: 4 months old (consider updating)
   ⚠️ xunlei: Up 2 days (no healthcheck) [CPU 11.2% — 疑似僵死]

• healthy_count: count of containers with "(healthy)" in status
• List containers WITHOUT "(healthy)" suffix under ⚠️
• If a container appears in TOP_CPU with same name → add [CPU X% — 疑似僵死]
• Image staleness: check IMG_AGE data; flag images older than 6 months with ℹ️
• Images: extract total size and reclaimable from DOCKER_DF
• If reclaimable > 10GB: · {reclaimable} reclaimable ⚠️
• If ALL containers are healthy: omit the detail lines, just show the summary

📹 FRIGATE — cameras, only expand problem ones:

text

📹 3 cams · detection:{det_fps}fps · infer:{infer_ms}ms
   ✅ cam_d82e8e00: 5.1fps · ✅ cam_ae7e3010: 5.1fps
   ⚠️ cam_a24a20c0: 4.9fps · skip:2.4 (丢帧 49%)

• Map camera IDs to friendly names via FRIGATE_CAM_MAP env var
• Show ALL camera names with fps (even healthy, but compact inline)
• Cameras with skip>0.5: show skip value + calculated drop percentage (skip/fps*100)
• Cameras with skip≤0.5: just show ✅ name: fps
• Storage: 📀 {path}: {used}G/{total}G ({pct}%) for each FRIGATE_STORAGE line. ⚠️ if >80%.
• If Frigate unreachable: 📹 Frigate: no response ❌

🎮 GPU — one line:

text

🎮 {gpu_model} · {temp}°C · {util}% · VRAM:{used}M/{total}M · {proc_count} procs

• VRAM bar: 10 chars proportional
• Omit GPU entirely if nvidia-smi not available or no GPU detected

🌐 NETWORK — one line per active interface:

text

🌐 enp4s0: {ip} · ↓{total_rx} ↑{total_tx}

• Skip DOWN interfaces
• Traffic: use TRAFFIC data, convert to human-readable (GB/MB)

📊 PROCESSES — top 3 CPU only (compact):

text

📊 CPU: xunlei 11.2% · ffmpeg 3.6% · python3 3.1%
   MEM: python3 3.6% · node 2.8% · gnome-shell 1.4%

⚙️ SERVICES — only show non-active or failed:

text

⚙️ ⚠️ nfs-server: inactive · 1 failed unit: snap.firmware-updater

• If all services active and no failed units: omit this section entirely

🔒 SECURITY — compact with full audit:

text

🔒 Failed logins: {count} · Boot: {boot_time_YYYY-MM-DD HH:MM} ({Xd} ago)
   SSH: port:{port} · root:{yes/no} · pass:{yes/no} · key:{yes/no}
   FW: {ufw/iptables status} ({n} rules) · Ports: {open_ports_list}

• SSH_PASS_AUTH=yes → ⚠️ alert (建议禁密码仅用密钥)
• SSH_ROOT_LOGIN=yes → ⚠️ alert (建议禁root直接登录)
• FW_UFW=inactive or FW_TYPE=none → ⚠️ alert (防火墙未启用)
• Convert OPEN_PORTS comma list to compact format: "22,80,443,8972,8973"
• Last logins: extract latest entry, reformat to "user from ip at YYYY-MM-DD HH:MM"
• If failed_logins = 0 → Failed logins: 0
• If fail2ban active → append · f2b active

🔋 UPS — one line:

text

🔋 {status_icon} {status_text} · charge:{batt_charge}% · load:{ups_load}% · in:{input_v}V · batt:{batt_v}V

• OL → ⚡Online, OB → 🪫Battery, OB DISCHRG → 🪫Discharging

💾 TIMESHIFT — one line with health check:

text

💾 Timeshift: {count} snaps · latest:{YYYY-MM-DD HH:MM}

• If 100 < count ≤ 300: append ⚠️ 过多，建议清理
• If count > 300: append ❌ 严重过多 (>300)，立即清理！

📦 UPDATES — only if > 0:

text

📦 {count} APT updates available

🔧 OOM / Logs — only if data present:

text

🔧 OOM: {oom_line_truncated}

Step 3: Final Assembly — Compact Mode

1. Title line (single row with date)

2. 🚨 ALERTS (if any) — combined, no section header duplication

3. ━━━━ divider (4 chars, not full-width)

4. Body sections — merge related sections inline:

   • 🖥 SYSTEM + 🌐 NETWORK on one block (host info → IP inline)
   • 🗄 ZFS + 💾 DISKS as one storage block
   • 🐳 DOCKER + 📹 FRIGATE as one container block
   • 🔒 SECURITY as standalone (important)
   • 📊 PROCESSES: only show if CPU>50% or unusual
   • ⚙️ SERVICES: only show failed
   • 🔋 UPS + 💾 TIMESHIFT + 📦 UPDATES as footer row

5. Keep total output under 2000 chars

6. Omitting rules:

   • Omit DISKIO if all util<5%
   • Omit PROCESSES if CPU<50% and no anomalies
   • Omit SERVICES if all active
   • Omit LOGS if no errors
   • Omit UPDATES if 0 pending
   • Omit GPU if nvidia-smi unavailable

3. Deliver#

Use message tool with action=send to the target channel.

• Camera name mapping is configurable via FRIGATE_CAM_MAP env var: cam_id:Name,cam_id:Name
• Pool name auto-detected from zpool list. Override with ZPOOL env var.
• Disk list auto-detected from lsblk. Override with DISK_LIST env var.
• Suitable for publishing to ClawHub — contains no credentials, tokens, or fixed identifiers.
