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。

#!/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。

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。
