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
然后是单台的分析脚本：
