本文实例为大家分享了python实时监控cpu的工具,供大家参考,具体内容如下

虽然写的很不完善,但是当练手吧,对于实时监控cpu还是有点用处的,虽然android studio已经提供了一样的功能,但是能够记录并生成成本地csv文件还是比as多一个功能的。

结果图:

直接放源码:


# !_*_coding:utf-8_*_

import re
import os
import wx
import thread
import pychartdir
import csv

class GetCpuStats():

 def __init__(self, name):
 self.pro_name = name

 def startWatch(self):
 _shell = 'adb shell top -s cpu -n 1| findstr %s' % self.pro_name
 result = os.popen(_shell).read()
 return self.getInfo(result)

 def getInfo(self, _result):
 return [re.findall('(\d+)%', _result), re.findall('K\s(\d+)K', _result)]

class MyFrame(wx.Frame):

 flag = False
 _label = []
 _data = []
 _label02 = []
 _data02 = []
 num = 0
 num02 = 0

 def __init__(self):
 wx.Frame.__init__(self, parent=None, title=u'cpu检测小工具', pos=(700, 100), size=(500, 500))
 mPanel = wx.Panel(parent=self)
 mSizer = wx.BoxSizer(orient=wx.VERTICAL)
 btn_start = wx.Button(parent=mPanel, label=u'开始', style=wx.EXPAND)
 mSizer.Add(btn_start)
 btn_stop = wx.Button(parent=mPanel, label=u'停止', style=wx.EXPAND)
 mSizer.Add(btn_stop)
 self.edit = wx.TextCtrl(parent=mPanel,style=wx.EXPAND,value=u'这里输入测试的包名')
 mSizer.Add(self.edit,flag=wx.EXPAND)
 self.edit.Bind(event=wx.EVT_CHOICE, handler=self.requestFocus)
 self.bitmap_cpu = wx.StaticBitmap(parent=mPanel)
 mSizer.Add(self.bitmap_cpu, flag=wx.EXPAND) 
 #self.bitmap_mem = wx.StaticBitmap(parent=mPanel)
 #mSizer.Add(self.bitmap_mem, flag=wx.EXPAND) 
 mPanel.SetSizer(mSizer)
 mPanel.Fit()
 btn_start.Bind(event=wx.EVT_BUTTON, handler=self.startWatch)
 btn_stop.Bind(event=wx.EVT_BUTTON, handler=self.stopWatch)

 def requestFocus(self,event):
 self.edit.SetValue("")

 def startWatch(self, event): 
 self.flag = True
 thread.start_new_thread(self.getInfo, ())

 def stopWatch(self, event):
 self.flag = False

 def getInfo(self):
 while(self.flag):
 _result = GetCpuStats(self.edit.GetValue()).startWatch()
 self.drawPic(_result)
 #self.drawPic_mem(_result)

 def writeCsv(self, _list):
 writer = csv.writer(file('tmp.csv', 'a+'))
 writer.writerow([_list])

 def drawPic(self,_list):
 self.num+=1
 self._label.append(str(self.num))
 self._data.append(_list[0][0])
 self.writeCsv(_list[0][0])
 c = pychartdir.XYChart(500, 400)
 c.setPlotArea(30, 20, 400, 300)
 c.addLineLayer(self._data)
 c.xAxis().setLabels(self._label)
 c.makeChart("tmp.png")
 mImage = wx.Image("tmp.png")
 mImage = mImage.Scale(500,300)
 self.bitmap_cpu.SetBitmap(wx.BitmapFromImage(mImage))

 def drawPic_mem(self,_list):
 self.num02+=1
 self._label02.append(str(self.num02))
 self._data02.append(_list[1][0])
 c = pychartdir.XYChart(500, 400)
 c.setPlotArea(60, 40, 400, 300)
 c.addLineLayer(self._data02)
 c.xAxis().setLabels(self._label02)
 c.makeChart("tmp02.png")
 mImage = wx.Image("tmp02.png")
 mImage = mImage.Scale(500,300)
 self.bitmap_mem.SetBitmap(wx.BitmapFromImage(mImage))

if __name__ == '__main__':
 app = wx.App()
 MyFrame().Show()
 app.MainLoop()

原理:

界面用wx做的,图形用pychartdir做的,命令用的是top命令,每次截取到的数据都生成一张临时图片,然后刷新到屏幕上,看起来就是实时数据监控的效果了,基本上BUG一大堆,也懒得改了。

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
