Share the load script of the python monitoring system in linux

This article mainly introduces how to use python to monitor system load scripts in linux. For more information, see the following code:

#! /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']

A brief description of listing 2: Listing 2 reads the information in/proc/loadavg. in import OS: Python, import is used to import different modules, including the system-provided and custom modules. The basic form is: import module name [as Alias]. if you only need to import part or all of the content in the module, you can use the form: from module name import * to import the corresponding module. The OS module provides a unified operating system interface function. the OS module can automatically switch between specific functions in different operating system platforms, such as nt and posix, to implement cross-platform operations.
You can use the Python command to run the script CPU1.py. The result is shown in figure 2.
