上一篇文章是转发了官方的zabbix监控squid的模版，兴奋之余把这个模版导入到squid后，却发现官方模版需要经过你的定制才能真正达到你的需求！
比如我导入模版之后，却发现没法出squid图片！
具体情况: 软件:squid 2.7 侦听端口: 8088
要实现在zabbix上监控squid, 要先看zabbix是如何获知squid的相关信息，squidclient mgr:info
完成以下三步，修改下模版即可完成你的监控需求！
第一步： 导入官方zabbix_server模版吧！上一篇文章附件中的模版！
第二步： 开启mgr的访问权限！
acl mgrcheng src 127.0.0.1
acl manager proto cache_object
http_access allow manager mgrcheng
http_access deny all
第二步：修改zabbix的客户端
我在原来的模块基础上根据我的环境修改了路径，添加了端口！
