树莓派CPU、GPU、磁盘、内存、负载监控脚本
经常需要快速的查看树莓派当前的CPU温度、GPU温度、树莓派内存使用、树莓派负载大小,还可以查看树莓派SD卡磁盘容量、已经使用量和使用百分比,本文提供了一个python脚本,可以解决这个需求。
树莓派CPU、GPU、磁盘、内存、负载监控脚本代码如下:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import commands
import os
def main():
# 查看GPU温度
gpu = float(gpu)
print('gpu Temp: %.2f ' % gpu)
# 查看CPU温度
file = open("/sys/class/thermal/thermal_zone0/temp")
cpu = float(file.read()) / 1000
file.close()
print('cpu Temp: %2.2f' % cpu)
load_1min = str(os.popen("top -n1 | awk '/load average:/ {print $12}'").readline().strip()).replace(',', '' )
load_5min = str(os.popen("top -n1 | awk '/load average:/ {print $13}'").readline().strip()).replace(',', '' )
load_1min=float(load_1min)
load_5min=float(load_5min)
print('')
print('load_1min: %.2f'%load_1min)
print('load_5min: %.2f'%load_5min)
Ramused = str(os.popen("top -n1 | awk '/KiB/ {print $6}'").readline().strip()).replace(',', '' )
Ramused = int(Ramused)
Ramused = Ramused / 1000
print('')
print('Ramused: %d '%Ramused +' Mb')
def getDiskSpace():
p = os.popen("df -h /")
i = 0
while 1:
i = i +1
line = p.readline()
if i==2:
return(line.split()[1:5])
# Disk information
DISK_stats = getDiskSpace()
DISK_total = DISK_stats[0].replace('G','')
DISK_used = DISK_stats[1].replace('G', '' )
DISK_perc = DISK_stats[3].replace('%', '' )
print('')
print('DISK_total: '+str(DISK_total)+' Gb')
print('DISK_used: '+str(DISK_used)+' Gb')
print('DISK_perc: '+str(DISK_perc)+' %')
if __name__ == '__main__':
main()
也可以直接下载脚本文件:https://github.com/xinxingli/raspberry
在本地将代码写入info.py文件,然后执行:
python info.py
就可以看到树莓派输出信息:
gpu Temp: 34.70
cpu Temp: 34.17
load_1min: 0.20
load_5min: 0.25
Ramused: 264 Mb
DISK_total: 15 Gb
DISK_used: 3.9 Gb
DISK_perc: 29 %
