本例主要功能：每隔3秒获取系统内存，当内存超过设定的警报值时，获取所有进程占用内存并发出警报声。内存值和所有进程占用内存记入log，log文件按天命名。

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)

2. 保存log

配置config文件

[loggers]
keys=example01
[logger_example01]
handlers=hand04

[handlers]
keys=hand04
[handler_hand04]
class=handlers.TimedRotatingFileHandler
level=DEBUG
formatter=form01
args=('./logs/monitor.log', 'd', 1, 7)

[formatters]
keys=form01,form02
[formatter_form01]
format=%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s
datefmt=%Y-%m-%d %H:%M:%S

记录log

import logging
import logging.config

logger.info("message")
logger.warning("message")
logger.error("message")

P70系列延期，华为新旗舰将在下月发布

3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。

而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？

根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
