Python统计日志中每个IP出现次数的方法
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-*-
importre,time
defmail_log(file_path):
globalcount
log=open(file_path,'r')
C=r'\.'.join([r'\d{1,3}']*4)
find=re.compile(C)
count={}
foriinlog:
foripinfind.findall(i):
count[ip]=count.get(ip,1)+1
if__name__=='__main__':
printtime.clock()
num=0
mail_log(r'e:\MDaemon-20110329-all.log')
R=count.items()
foriinR:
ifi[1]>0:#提取出现次数大于0的IP
printi
num+=1
print'符合要求数量：%s耗时(%s)'%(num,time.clock())
输出结果如下：
