RDK X5 Monitor — 系统监控

操作步骤

1. CPU 状态

# CPU 使用率（实时）
top -bn1 | head -5

# 各核频率
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq

# 调度策略
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

2. BPU 算力监控

# BPU 使用率（0~100）
cat /sys/devices/system/bpu/bpu0/ratio

# BPU 频率
cat /sys/devices/system/bpu/bpu0/devfreq/*/cur_freq

3. 温度

# 芯片温度（除以 1000 = ℃）
cat /sys/class/thermal/thermal_zone0/temp

# BPU 温度
cat /sys/class/hwmon/hwmon0/temp1_input

超过 95°C 自动降频，极限 105°C。

4. 内存与磁盘

free -h              # 内存
df -h                # 磁盘

5. GPU 频率

cat /sys/class/devfreq/*/cur_freq 2>/dev/null | head -1

6. 网络 IP

ip -4 addr show | grep inet | grep -v 127.0.0.1
hostname -I

7. 一键状态总览

echo "=== CPU ===" && top -bn1 | head -5 && 
echo "=== BPU ===" && cat /sys/devices/system/bpu/bpu0/ratio 2>/dev/null && 
echo "=== Temp ===" && echo "$(($(cat /sys/class/thermal/thermal_zone0/temp)/1000))°C" && 
echo "=== Mem ===" && free -h | head -2 && 
echo "=== Disk ===" && df -h / | tail -1 && 
echo "=== IP ===" && hostname -I

8. 持续监控（每 2 秒刷新）

watch -n 2 'echo "CPU: $(top -bn1 | grep Cpu | head -1)" && 
echo "BPU: $(cat /sys/devices/system/bpu/bpu0/ratio 2>/dev/null)%" && 
echo "Temp: $(($(cat /sys/class/thermal/thermal_zone0/temp)/1000))°C" && 
free -h | head -2'
