Python实现获取nginx服务器ip及流量统计信息功能示例
本文实例讲述了Python实现获取nginx服务器ip及流量统计信息功能。分享给大家供大家参考，具体如下：
#!/usr/bin/python
#coding=utf8
log_file="/usr/local/nginx/logs/access.log"
withopen(log_file)asf:
contexts=f.readlines()
#defineipdict###
ip={}#key为ip信息，value为ip数量（若重复则只增加数量）
flow={}#key为ip信息，value为流量总和
sum=0
forlineincontexts:
#countrowsizeofflow
size=line.split()[9]
#printip
ip_attr=line.split()[0]
#counttotalsizeofflow
sum=int(size)+sum
ifip_attrinip.keys():#ifiprepeated，如果ip重复就将ip数量加一，而流量继续叠加
#countofipplus1
ip[ip_attr]=ip[ip_attr]+1
#sizeofflowplussize
flow[ip_attr]=flow[ip_attr]+int(size)
else:
#ifipnotrepeated
#defineinitialvaluesofcountofipandsizeofflow
ip[ip_attr]=1
flow[ip_attr]=int(size)
print(ip)
print(flow)
print(sum/1024/1024)
现在有nginx的访问日志：

利用python将nginx的ip进行统计
思路：将文件内容一行一行都出来，然后进行字符串strip().split()，得到一个列表，列表的第一个元素就是ip的内容
初始化一个空字典，用key表示ip内容，value表示该ip的个数，如果ip重复了，则将value进行增加：
[root@weblogic~]#catnginx.py
#!/usr/bin/python
#coding=utf8
log_file="/root/access.log"
ip={}
withopen(log_file)asf:
foriinf.readlines():
printi.strip().split()[0]
ip_attr=i.strip().split()[0]
ifip_attrinip.keys():#如果ip存在于字典中，则将该ip的value也就是个数进行增加
ip[ip_attr]=ip[ip_attr]+1
else:
ip[ip_attr]=1
printip
获取执行结果：
[root@weblogic~]#pythonnginx.py
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
{'192.168.223.1':5,'192.168.223.136':5}
