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)])

    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

    f = open("/proc/loadavg")
    loadstate=f.read().split()
    return loadstate

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)

    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")
    loadstate=f.read().split()

    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)))
