本文實例講述了Python實現獲取nginx服務器ip及流量統計信息功能。分享給大家供大家參考，具體如下：

#!/usr/bin/python

#coding=utf8

log_file = "/usr/local/nginx/logs/access.log"

with open(log_file) as f:

contexts = f.readlines()

# define ip dict###

ip = {} # key為ip信息，value為ip數量(若重復則只增加數量)

flow = {} # key為ip信息，value為流量總和

sum = 0

for line in contexts:

# count row size of flow

size = line.split()[9]

# print ip

ip_attr = line.split()[0]

# count total size of flow

sum = int(size) + sum

if ip_attr in ip.keys(): # if ip repeated，如果ip重復就將ip數量加一，而流量繼續疊加

# count of ip plus 1

ip[ip_attr] = ip[ip_attr] + 1

# size of flow plus size

flow[ip_attr] = flow[ip_attr] + int(size)

else:

# if ip not repeated

# define initial values of count of ip and size of flow

ip[ip_attr] = 1

flow[ip_attr] = int(size)

print(ip)

print(flow)

print(sum/1024/1024)

現在有nginx的訪問日志：

[root@weblogic ~]# cat access.log

利用python將nginx的ip進行統計

思路：將文件內容一行一行都出來，然后進行字符串strip().split()，得到一個列表，列表的第一個元素就是ip的內容

初始化一個空字典，用key表示ip內容，value表示該ip的個數，如果ip重復了，則將value進行增加：

[root@weblogic ~]# cat nginx.py

#!/usr/bin/python

#coding=utf8

log_file = "/root/access.log"

ip = {}

with open(log_file) as f:

for i in f.readlines():

print i.strip().split()[0]

ip_attr = i.strip().split()[0]

if ip_attr in ip.keys(): # 如果ip存在于字典中，則將該ip的value也就是個數進行增加

ip[ip_attr] = ip[ip_attr] + 1

else:

ip[ip_attr] = 1

print ip

獲取執行結果：

[root@weblogic ~]# python nginx.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}
