使用Python获取CPU、内存和硬盘等windowns系统信息的2个例子

例子一：

Python用WMI模块获取windowns系统的硬件信息：硬盘分区、使用情况，内存大小，CPU型号，当前运行的进程，自启动程序及位置，系统的版本等信息。

代码如下:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import wmi
import os
import sys
import platform
import time

def sys_version(): 
    c = wmi.WMI ()
    #获取操作系统版本
    for sys in c.Win32_OperatingSystem():
        print "Version:%s" % sys.Caption.encode("UTF8"),"Vernum:%s" % sys.BuildNumber
        print  sys.OSArchitecture.encode("UTF8")#系统是32位还是64位的
        print sys.NumberOfProcesses #当前系统运行的进程总数

def cpu_mem():
    c = wmi.WMI ()       
    #CPU类型和内存
    for processor in c.Win32_Processor():
        #print "Processor ID: %s" % processor.DeviceID
        print "Process Name: %s" % processor.Name.strip()
    for Memory in c.Win32_PhysicalMemory():
        print "Memory Capacity: %.fMB" %(int(Memory.Capacity)/1048576)

def cpu_use():
    #5s取一次CPU的使用率
    c = wmi.WMI()
    while True:
        for cpu in c.Win32_Processor():
             timestamp = time.strftime('%a, %d %b %Y %H:%M:%S', time.localtime())
             print '%s | Utilization: %s: %d %%' % (timestamp, cpu.DeviceID, cpu.LoadPercentage)
             time.sleep(5)

def disk():
    c = wmi.WMI ()   
    #获取硬盘分区
    for physical_disk in c.Win32_DiskDrive ():
        for partition in physical_disk.associators ("Win32_DiskDriveToDiskPartition"):
            for logical_disk in partition.associators ("Win32_LogicalDiskToPartition"):
                print physical_disk.Caption.encode("UTF8"), partition.Caption.encode("UTF8"), logical_disk.Caption

#获取硬盘使用百分情况
    for disk in c.Win32_LogicalDisk (DriveType=3):
        print disk.Caption, "%0.2f%% free" % (100.0 * long (disk.FreeSpace) / long (disk.Size))

def network():
    c = wmi.WMI ()    
    #获取MAC和IP地址
    for interface in c.Win32_NetworkAdapterConfiguration (IPEnabled=1):
        print "MAC: %s" % interface.MACAddress
    for ip_address in interface.IPAddress:
        print "ip_add: %s" % ip_address
    print

#获取自启动程序的位置
    for s in c.Win32_StartupCommand ():
        print "[%s] %s <%s>" % (s.Location.encode("UTF8"), s.Caption.encode("UTF8"), s.Command.encode("UTF8"))

#获取当前运行的进程
    for process in c.Win32_Process ():
        print process.ProcessId, process.Name

def main():
    sys_version()
    #cpu_mem()
    #disk()
    #network()
    #cpu_use()

if __name__ == '__main__':
    main()
    print platform.system()
    print platform.release()
    print platform.version()
    print platform.platform()
    print platform.machine()

例子二：

由于我用到的不多，所以只获取的CPU、内存和硬盘，如果需要其它资源，请参照msdn。

代码如下:

import os
import win32api
import win32con
import wmi
import time

def getSysInfo(wmiService = None):
    result = {}
    if wmiService == None:
        wmiService = wmi.WMI()
    # cpu
    for cpu in wmiService.Win32_Processor():
        timestamp = time.strftime('%a, %d %b %Y %H:%M:%S', time.localtime())
        result['cpuPercent'] = cpu.loadPercentage
    # memory
    cs = wmiService.Win32_ComputerSystem()
    os = wmiService.Win32_OperatingSystem()
    result['memTotal'] = int(int(cs[0].TotalPhysicalMemory)/1024/1024)
    result['memFree'] = int(int(os[0].FreePhysicalMemory)/1024)
    #disk
    result['diskTotal'] = 0
    result['diskFree'] = 0
    for disk in wmiService.Win32_LogicalDisk(DriveType=3):
        result['diskTotal'] += int(disk.Size)
        result['diskFree'] += int(disk.FreeSpace)
    result['diskTotal'] = int(result['diskTotal']/1024/1024)
    result['diskFree'] = int(result['diskFree']/1024/1024)
    return result

if __name__ == '__main__':
    wmiService = wmi.WMI()
    while True:
        print getSysInfo(wmiService)
        time.sleep(3)

采用的wmi模块获取的，由于wmi初始化时占用系统资源太高，所以如果需要循环获取，请在循环体外面把wmi对象初始化好，然后传入函数里面，这样就不会产生CPU资源过高的情况。
