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.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 osimport win32apiimport win32conimport wmiimport 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。
