python3 输出系统信息

一、安装psutil库

pip3 install psutil

二、代码

#!/usr/bin/python3 coding=utf-8

import psutil

import uuid

import socket

import os

#系统与磁盘挂载

print('##########系统与磁盘信息#########')

def get_mac_address():

    mac=uuid.UUID(int = uuid.getnode()).hex[-12:]

    return ":".join([mac[e:e+2] for e in range(0,11,2)])

def get_host_ip():

    try:

        s=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

        s.connect(('8.8.8.8',80))

        ip=s.getsockname()[0]

    finally:

        s.close()

    return ip

def get_load():

    f = open("/proc/loadavg")

    loadstate=f.read().split()

    return loadstate

for i in load_list:

    if system_load:

        system_load = system_load+','+i

    else:

print('主机名称:',myname)

print('本机ip地址:',get_host_ip())

print('本机MAC地址:',get_mac_address())

print('系统负载(1,5,15分钟):',system_load)

print('系统进程数:',len(psutil.pids()))

devs = psutil.disk_partitions()

for dev in devs:

    statvfs = os.statvfs(dev.mountpoint)

devs = psutil.disk_partitions()

for dev in devs:

    statvfs = os.statvfs(dev.mountpoint)

    total_disk_space = statvfs.f_frsize * statvfs.f_blocks

    free_disk_space = statvfs.f_frsize * statvfs.f_bfree

    disk_usage = int((total_disk_space - free_disk_space) * 100.0 / total_disk_space)

    print('挂在设备：%s，挂载点：%s 磁盘使用率:%d%%  文件系统:%s' % (dev.device,dev.mountpoint,disk_usage,dev.fstype))

#系统负载

def get_load():

    f = open("/proc/loadavg")

    else:

        system_load = i

print('系统负载(1,5,15分钟):',system_load)

#cpu

cts = psutil.cpu_times()

cputime = 0

for item in cts:

    if item != 0:

        cputime = cputime + item

print('########CPU信息#########')

print('用户时间：%d%%' % (cts.user/cputime * 100))

print('内核时间：%d%%' % (cts.system/cputime * 100))

print('空闲时间：%d%%' % (cts.idle/cputime * 100))

print('逻辑CPU个数:',psutil.cpu_count())

print('物理cpu数量:',psutil.cpu_count(logical=False))

#内存

print('#########内存信息############')

mem = psutil.virtual_memory()

print('内存大小: %dM'%(int(mem.total/1024/1024)))

print('已使用内存: %dM'%(int(mem.used/1000/1000)))

print('剩余内存:%dM'%(int(mem.free/1024/1024)))

print('内存使用率: %d%%'%(int(mem.percent)))

三、运行结果
