这篇文章将为大家详细讲解有关python实现简易内存监控的方法，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1 获取cpu、内存、进程信息
利用WMI
简单说明下，WMI的全称是Windows Management Instrumentation，即Windows管理规范。它是Windows操作系统上管理数据和操作的基础设施。我们可以使用WMI脚本或者应用自动化管理任务等。

不错的教程
获取cpu、内存、磁盘
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)
result['memPercent']=result['memFree'] * 100 /result['memTotal']
#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获取所有进程占用内存
def getAllProcessInfo(mywmi = None):
"""取出全部进程的进程名，进程ID，进程实际内存, 虚拟内存,CPU使用率
"""
allProcessList = []
allProcess = mywmi.ExecQuery("SELECT * FROM Win32_PerfFormattedData_PerfProc_Process")
#print (allProcess.count)
for j in allProcess:
#print j.Properties_("PercentPrivilegedTime").__int__()
##print j.Properties_("name").__str__()+" "+j.Properties_("IDProcess").__str__()+" "+j.Properties_("PercentPrivilegedTime").__str__()
#for pro in j.Properties_:
# print (pro.name)
#break
name = j.Properties_("name").__str__()
if name != "_Total" and name !="Idle":
pid = j.Properties_("IDProcess").__str__()
PercentPrivilegedTime = j.Properties_("PercentPrivilegedTime").__int__()
WorkingSetPrivate = j.Properties_("WorkingSetPrivate").__int__()/1024
WorkingSet = j.Properties_("WorkingSet").__int__()/1024
allProcessList.append([name, pid, WorkingSetPrivate, WorkingSet, PercentPrivilegedTime])
return allProcessList也可以用psutil
import psutil,time from operator import itemgetter, attrgetter def getProcessInfo(p): """取出指定进程占用的进程名，进程ID，进程实际内存, 虚拟内存,CPU使用率 """ try: cpu = int(p.cpu_percent(interval=0)) memory = p.memory_info() rss = memory.rss/1024 vms = memory.vms/1024 name = p.name() pid = p.pid except psutil.Error: name = "Closed_Process" pid = 0 rss = 0 vms = 0 cpu = 0 #return [name.upper(), pid, rss, vms] return [name, pid, vms, rss, cpu] def getAllProcessInfo(): """取出全部进程的进程名，进程ID，进程实际内存, 虚拟内存,CPU使用率 """ instances = [] all_processes = list(psutil.process_iter()) for proc in all_processes: proc.cpu_percent(interval=0) #此处sleep1秒是取正确取出CPU使用率的重点 time.sleep(1) for proc in all_processes: instances.append(getProcessInfo(proc)) return instances if __name__ == '__main__': processInfoList = getAllProcessInfo() processInfoList.sort(key=itemgetter(2), reverse=True) for p in processInfoList: print(p)
