python脚本实现统计日志文件中的ip访问次数代码分享

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
example log.py log.log 20
code by iswin')
 sys.exit()
 dic={}
 log=Log(sys.argv[1],dic,sys.argv[2])
 log.parse()
