Linux systems use python to monitor system load script sharing

#!/usr/bin/env Python   
import os 
def load_stat(): 
    loadavg = {} 
    f = open("/proc/loadavg") 
    con = f.read().split() 
    f.close() 
    loadavg['lavg_1']=con[0] 
    loadavg['lavg_5']=con[1] 
    loadavg['lavg_15']=con[2] 
    loadavg['nr']=con[3] 
    loadavg['last_pid']=con[4] 
    return loadavg 
print "loadavg",load_stat()['lavg_15']

Listing 2: listing 2 reads the information in /proc/loadavg, import OS: in Python, import is used to import different modules, including system-provided and custom modules. Its basic form is: import module name [as alias], if only need to import part or all of the contents of the module can use the form: from module name import * to import the corresponding module. OS module OS module provides a unified operating system interface function, the OS module can automatically switch between different operating system platforms such as nt, posix in the specific functions, so as to achieve cross-platform operation.
You can use the Python command to run the script cpu1.py as shown in figure 2
