python脚本实现统计日志文件中的ip访问次数代码分享

适用的日志格式：

106.45.185.214 - - [06/Aug/2014:07:38:59 +0800] "GET / HTTP/1.0" 200 10 "-" "-"
171.104.119.22 - - [06/Aug/2014:08:55:01 +0800] "GET / HTTP/1.0" 200 10 "-" "-"
27.31.238.242 - - [06/Aug/2014:09:43:19 +0800] "GET / HTTP/1.0" 200 10 "-" "-"
218.65.202.131 - - [06/Aug/2014:10:33:59 +0800] "GET / HTTP/1.0" 200 10 "-" "-"

以上为nginx的日志,本程序只适合用于IP在开头并用空格分开的这种格式。

实例代码：

import sys
 
class Log:
 
  def __init__(self, filename,dic,count):
    self.filename = filename
    self.dic=dic
    self.count=count
 
  def parse(self):
    i=1
    f=file(self.filename)
    while True:
      line=f.readline()
      if len(line)==0:
        break
      ip=line.split(' ')
      if ip[0] in dic:
        self.dic[ip[0]]=self.dic[ip[0]]+1
      else:
        self.dic[ip[0]]=i
    soredic=sorted(self.dic.items(), key=lambda d:d[1],reverse=True)
    counts=0;
    for item in soredic:
      if counts==int(self.count):
        break
      print("IP:%s  Total Times: %s"%(item[0],item[1]))
      counts=counts+1
    f.close()
 
if __name__=="__main__":
 
  if len(sys.argv)<3:
    print('usage:log.py log.log toptimes\nexample log.py log.log 20\ncode by iswin')
    sys.exit()
  dic={}
  log=Log(sys.argv[1],dic,sys.argv[2])
  log.parse()
