Python统计日志中每个IP出现次数的方法

概述本文实例讲述了Python统计日志中每个IP出现次数的方法。分享给大家供大家参考。具体如下：

本文实例讲述了Python统计日志中每个IP出现次数的方法。分享给大家供大家参考。具体如下：

这脚本可用于多种日志类型,本人测试MDaemon的all日志文件大小1.23G左右,分析用时2~3分钟

代码很简单,很适合运维人员,有不足的地方请大家指出哦

#-*- Coding:utf-8 -*-import re,timedef mail_log(file_path):  global count  log=open(file_path,'r')  C=r'\.'.join([r'\d{1,3}']*4)  find=re.compile(C)  count={}  for i in log:    for ip in find.findall(i):      count[ip]=count.get(ip,1)+1if __name__ == '__main__':  print time.clock()  num=0  mail_log(r'e:\MDaemon-20110329-all.log')  R=count.items()  for i in R:    if i[1]>0: #提取出现次数大于0的IP      print i      num+=1  print '符合要求数量：%s耗时(%s)'%(num,time.clock())

输出结果如下：
