利用python获取nginx服务的ip以及流量统计信息

#!/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

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重复就将ip数量加一，而流量继续叠加
	# 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) 

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 ~]# 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，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
 
print ip

获取执行结果：

[root@weblogic ~]# python nginx.py
