"Raspberry Pi" gets the current temperature, CPU, memory, and the state of the hard disk

Go to a script written in Python that outputs the various states and data of the Raspberry Pi, including CPU temperature, CPU usage, memory usage, and hard disk usage.

Article from: Raspberry Pi Lab

First, create a script:

sudo nano get.py

Second, paste the following code: Bash

Import OS # Return CPU temperature as a character string Def getcputemperature (): res = Os.popen (' Vcgencmd measure_temp '). ReadLine () Return (Res.replace ("temp=", ""). Replace ("' c\n '," ")) # return RA                                                              
M information (unit=kb) in a list # Index 0:total RAM # Index 1:used RAM # Ind
    Ex 2:free RAM def getraminfo (): p = os.popen (' free ') i = 0 while 1:i = i + 1 line = P.readline () if I==2:return (Line.split () [1:4] ) # return% of CPU used by user as a character string Def getcpuuse (): Return (str (OS . Popen ("top-n1 | awk '/cpu\ (s\):/           {print $} '). ReadLine (). Strip ()) # Return information about disk space as a list (unit included)         
# index 0:total disk space # index 1:used disk space                                                    
# Index 2:remaining disk space
    # Index 3:percentage of disk used 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]) # CPU Informatiom cpu_temp = getcputemperature () Cpu_usage = Getcpuuse () # RAM Informati  On # Output are in kilobytes, here I-convert it in Mb for readability ram_stats = Getraminfo () ram_total = round (int (ram_stats[0))
/1000,1) ram_used = round (int (ram_stats[1])/1000,1) Ram_free = round (int (ram_stats[2])/1000,1) # Disk Information Disk_stats = Getdiskspace () disk_total = disk_stats[0] disk_used = disk_stats[1] Disk_perc = disk_stats[3] if __name__ = = ' __main__ ': print (Print (' CPU temperature = ' +cpu_temp) print (' CPU use = ' +cpu_usage) print (") print (' RAM total = ' +str ( 
    ram_total) + ' MB ') print (' Ram used = ' +str (ram_used) + ' MB ') print (' Ram free = ' +str (ram_free) + ' MB ') print (') Print (' disk total Space = ' +str (disk_total) + ' B ') print (' disk used space = ' +str (disk_used) + ' B ') print (' Disk U sed Percentage = ' +str (DISK_PERC))

Third, execute script: Bash

chmod +x get.py  #赋予可执行权限
python get.py    #执行脚本

The expected output results are as follows: Bash

CPU temperature = 53.0
CPU use = 13.5
 
ram total = 497.0 MB
ram used = 116.0 MB
RAM free = 381.0 MB
 
DIS K Total Space = 3.6GB
disk used Space = 1.8GB
disk used Percentage = 53%
