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/' target='_blank'>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。

复制代码 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。

复制代码 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。
