前面我们已经学习过了，如何收集网站服务质量的一些相关数据，然后通过入库出图，开始打算是用rrdtool做画图，但是经过一段时间的研究，发现echarts出图合理和美观，下面贴出我实时收集到的数据和出图展示部分:

1、数据收集，并且格式化形成字典:

 #!/usr/bin/env python
# -*- coding: utf-8 -*-  
 import os,sys,json   
 import time   
 import sys   
 import pycurl  
 class Test: 
     def __init__(self): 
         self.contents = '' 
     def callback(self,buf): 
         self.contents = self.contents + buf 
 def test_gzip(input_url): 
     data = {} 

      t = Test()  
     c = pycurl.Curl()   
     c.setopt(pycurl.WRITEFUNCTION,t.callback) 
     c.setopt(pycurl.ENCODING, 'gzip') 
     c.setopt(pycurl.URL,input_url)  
     c.perform()     
     NAMELOOKUPTIME =  c.getinfo(c.NAMELOOKUP_TIME)   
     CONNECTTIME =  c.getinfo(c.CONNECT_TIME)  
     PRETRANSFERTIME =   c.getinfo(c.PRETRANSFER_TIME)          
     STARTTRANSFERTIME = c.getinfo(c.STARTTRANSFER_TIME)    
     TOTALTIME = c.getinfo(c.TOTAL_TIME) 
     HTTPCODE =  c.getinfo(c.HTTP_CODE)   
     SIZEDOWNLOAD =  c.getinfo(c.SIZE_DOWNLOAD)   
     HEADERSIZE = c.getinfo(c.HEADER_SIZE)    
     SPEEDDOWNLOAD=c.getinfo(c.SPEED_DOWNLOAD)  
     data["HTTPCODE"]= HTTPCODE 

   data["NAMELOOKUPTIME"]="%.2f"%(NAMELOOKUPTIME*1000)   
      data["CONNECTTIME"]="%.2f"%(CONNECTTIME*1000)  
      data["PRETRANSFERTIME"]="%.2f"%(PRETRANSFERTIME*1000)   
      data["STARTTRANSFERTIME"]="%.2f"%(STARTTRANSFERTIME*1000) 
      data["TOTALTIME"]="%.2f"%(TOTALTIME*1000) 
      data["SIZEDOWNLOAD"]="%d"%(SIZEDOWNLOAD)   
      data["HEADERSIZE"] ="%d"%(HEADERSIZE)   
      data["SPEEDDOWNLOAD"]="%d"%(SPEEDDOWNLOAD) 
      return data   
 if __name__ == '__main__': 
     input_url = sys.argv[1] 
     print test_gzip(input_url) 

2、后端处理数据，格式化输出:

  def pycurl(request): 
         cmd = "python  %s/backend/pcurl.py www.shikee.com" %('/yizhan/oms/app01') 
         data = os.popen(cmd).read() 
         data=eval(data)   #这个函数害苦我了，开始怎么设置都不对，调用eval之后搞定 
         NAMELOOKUPTIME=float(data['NAMELOOKUPTIME']) 
         CONNECTTIME=float(data['CONNECTTIME']) 
         PRETRANSFERTIME=float(data['PRETRANSFERTIME']) 
         STARTTRANSFERTIME=float(data['STARTTRANSFERTIME']) 
         TOTALTIME=float(data['TOTALTIME']) 
         SPEEDDOWNLOAD=float(data['SPEEDDOWNLOAD']) 
         return render_to_response('pycurl.html',{'NAMELOOKUPTIME':NAMELOOKUPTIME,'CONNECTTIME':CONNECTTIME,'PRETRANSFERTIME':PRETRANSFERTIME,'STARTTRANSFERTIME':STARTTRANSFERTIME,'TOTALTIME':TOTALTIME,'SPEEDDOWNLOAD':SPEEDDOWNLOAD}) 

3、出图的小代码:

  var myChart = ec.init(document.getElementById('main'));  
                  
                 var option = { 
                     tooltip: { 
                         show: true 
                     }, 
                     legend: { 
                         data:['www.shikee.com'] 
                     }, 
                     xAxis : [ 
                         { 
                             type : 'category', 
                             data : ["DNS解析时间","建立连接时间","重定向消耗时间","传输结束时间","传输结束时间"] 
                         } 
                     ], 
                     yAxis : [ 
                         { 
                             type : 'value' 
                         } 
                     ], 
                     series : [
