## Full Health Snapshot (run all at once)

```bash
echo "=== $(date) ===" && \
echo "--- UPTIME ---" && uptime && \
echo "--- CPU ---" && grep -c ^processor /proc/cpuinfo && cat /proc/loadavg && \
echo "--- RAM ---" && free -h && \
echo "--- DISK ---" && df -h / && \
echo "--- CONTAINERS ---" && docker ps --format "table {{.Names}}\t{{.Status}}" 2>/dev/null && \
echo "--- arifOS ---" && curl -sf http://arifosmcp:8080/health | python3 -c "import sys,json; d=json.load(sys.stdin); print(f\"status={d['status']} tools={d.get('tools_loaded','?')}\")" 2>/dev/null
```

## Network Speed Test

### Download speed (Cloudflare — no install needed)
```bash
# 10MB test file from Cloudflare
SPEED=$(curl -s -o /dev/null -w "%{speed_download}" \
  "https://speed.cloudflare.com/__down?bytes=10000000" --max-time 15)
echo "Download: $(echo "scale=1; ${SPEED}/1048576" | bc) MB/s"
```

### Latency to key endpoints
```bash
for HOST in 1.1.1.1 8.8.8.8 api.anthropic.com api.moonshot.cn; do
  RTT=$(curl -s -o /dev/null -w "%{time_connect}s" "https://${HOST}" --max-time 5 2>/dev/null || echo "timeout")
  echo "${HOST}: ${RTT}"
done
```

### Upload speed (to your own VPS — internal)
```bash
# From container to arifOS MCP endpoint
dd if=/dev/urandom bs=1M count=5 2>/dev/null | \
  curl -s -X POST http://arifosmcp:8080/health \
  -H "Content-Type: application/octet-stream" \
  --data-binary @- -o /dev/null -w "upload: %{speed_upload} B/s\n"
```

### Quick ping test (DNS resolution speed)
```bash
for HOST in arifosmcp headless_browser qdrant ollama_engine arifos-postgres; do
  TIME=$(curl -sf -o /dev/null -w "%{time_namelookup}+%{time_connect}" http://${HOST} 2>/dev/null || echo "unreachable")
  echo "${HOST}: ${TIME}s"
done
```

## CPU & Process Analysis

```bash
# Top CPU consumers
ps aux --sort=-%cpu | head -10

# Top memory consumers
ps aux --sort=-%mem | head -10

# CPU info
nproc && cat /proc/loadavg

# Check if load is high
LOAD=$(cat /proc/loadavg | cut -d' ' -f1)
CORES=$(nproc)
echo "Load: ${LOAD} / ${CORES} cores"
# If load > cores: system under pressure
```

---

## Disk Analysis

```bash
# Overall usage
df -h

# Find disk hogs (top 10 largest dirs)
du -h / --max-depth=3 2>/dev/null | sort -rh | head -10

# Docker-specific disk usage
docker system df

# Ollama model sizes
docker exec ollama_engine du -sh /root/.ollama/models/ 2>/dev/null

# Log sizes
du -sh /opt/arifos/data/openclaw/logs/ /var/log/ 2>/dev/null
```

## Disk Alert Thresholds

```bash
USED=$(df / | awk 'NR==2{print $5}' | tr -d '%')
if [ "$USED" -gt 85 ]; then
  echo "DISK_CRITICAL: ${USED}% — immediate cleanup required"
  echo "Run: docker builder prune -f && docker image prune -f"
elif [ "$USED" -gt 75 ]; then
  echo "DISK_WARNING: ${USED}% — monitor closely"
else
  echo "DISK_OK: ${USED}%"
fi
```

## RAM Analysis

```bash
# Full memory breakdown
