python模块--psutil: 跨平台的设备监控模块(CPU, 内存, 硬盘,网络,传感器(温度、风扇、电池))

转摘文章：python模块--psutil: 跨平台的设备监控模块(CPU, 内存, 硬盘,网络,传感器(温度、风扇、电池))_浅弋、璃鱼的博客-CSDN博客

 

一、概要:

psutil（进程和系统实用程序）是一个跨平台库，用于 在Python中检索有关正在运行的进程和系统利用率（CPU，内存，磁盘，网络，传感器）的信息。它主要用于系统监视，分析和限制流程资源以及运行流程的管理。它实现了UNIX命令行工具提供的许多功能，例如：ps，top，lsof，netstat，ifconfig，who，df，kill，free，nice，ionice，iostat，iotop，uptime，pidof，tty，taskset，pmap。psutil目前支持以下平台：

 

linux;

windows;

mac os

FreeBSD, OpenBCD, NetBsd;

AIX;

…

支持32位和64位的架构;

支持python>=2.6; python>=3.4

二、安装:

github: https://github.com/giampaolo/psutil

pypi: https://pypi.org/project/psutil/

使用pip包管理利器直接安装:

pip install psutil

　

三、具体实例

1. CPU:

# 去获取cpu的详细信息cpus = psutil.cpu_times()print("CPU的详细信息:{}".format(cpus))

# psutil获取系统cpu使用率的方法是cpu_percent()# 两个参数，分别是interval和percpu,# interval指定的是计算cpu使用率的时间间隔，# percpu则指定是选择总的使用率还是每个cpu的使用率。(默认为False)percent = psutil.cpu_percent(interval=1)print(f"当前CPU总使用率为:{percent}%")
percent = psutil.cpu_percent(interval=1, percpu=True)print(f"当前每个CPU使用率为:{percent}")
