之前在做cdn运维的时候，因为业务的特殊性（跨机房，跨ISP，跨区域），把日志集中传输到一个中心来做qos的分析不太现实，因此采用的方法是每5分钟对Nginx日志进行切割，然后通过Python程序计算http code的分布，并通过Zabbix来实现单台机器Nginx qos的监控，配合对Zabbix数据库的Lastvalue进行聚合，则可以监控整个CDN的流量，qos数据等，这样一般发现问题的延迟就在5分钟左右（cdn的qos敏感性不是很强）,配合rsync+hadoop+hive来计算nginx的日志，也可以得到更加详细的各个维度的分析（离线数据分析），下面贴下Nginx日志使用的分析脚本：

先贴下zabbix聚合脚本：

#!/usr/bin/python #to get webcdn totaol statistics # -*- coding: utf8 -*- import MySQLdb import sys import os def get_total_value(sql):     db = MySQLdb.connect(host='xxxx',user='xxxx',passwd='xxxx',db='xxxx')     cursor = db.cursor()     cursor.execute(sql)     try:           result = cursor.fetchone()[0]     except:         result = 0     cursor.close()     db.close()     return result if __name__ == '__main__':     sql = ''     if sys.argv[1] == "network_traffic":         sql = "select round(sum(lastvalue)/(1024*1024),4) from  hosts a, items b   where key_ in ( 'net.if.out[eth2,bytes]','net.if.out[eth0,bytes]') and lower(host) like '%-cdn-cache%'  and a.hostid = b.hostid"     elif sys.argv[1] == "nginx_traffic":         sql = "select sum(lastvalue) from  hosts a, items b   where key_ = 'log_webcdn_getvalue[traffic]'   and lower(host) like '%cdn-cache%'  and a.hostid = b.hostid"     elif sys.argv[1] == "2xxand3xx":         sql = "select sum(lastvalue) from  hosts a, items b   where key_ in ( 'log_webcdn_getvalue[200]','log_webcdn_getvalue[300]') and lower(host) like '%-cdn-cache%'  and a.hostid = b.hostid"     elif sys.argv[1] == "4xxand5xx":         sql = "select sum(lastvalue) from  hosts a, items b   where key_ in ( 'log_webcdn_getvalue[four]','log_webcdn_getvalue[five]') and lower(host) like '%-cdn-cache%'  and a.hostid = b.hostid"     elif sys.argv[1] == "network_ss":         sql = "select sum(lastvalue) from  hosts a, items b   where key_ = 'network_conn' and lower(host) like '%-cdn-cache%'  and a.hostid = b.hostid"     else:         sys.exit(0) #    print sql     value = get_total_value(sql)     print value
