最近要监控 ATS，使用 stats_over_http.so 模块可以使用 url 来查看 ats 的状态，在 cacti 里面加上了几个值来监控，包含：
proxy.process.http.completed_requests

Cacti 利用 stats_over_http.so 模块监控 ats 的部分数据下载：

所有收到请求，使用 count 模式统计每秒完成的请求
proxy.process.http.incoming_requests
proxy.process.http.outgoing_requests
进入和出的请求，基本能够描述 ats 的繁忙程度
proxy.process.http.1xx_responses
proxy.process.http.2xx_responses
proxy.process.http.3xx_responses
proxy.process.http.4xx_responses
proxy.process.http.5xx_responses
给客户端返回的 HTTP status code 的数量，基本反映服务情况
proxy.process.http.tcp_hit_count_stat
proxy.process.http.tcp_refresh_hit_count_stat
proxy.process.http.tcp_ims_hit_count_stat
proxy.process.http.tcp_miss_count_stat
proxy.process.http.tcp_refresh_miss_count_stat
proxy.process.http.tcp_ims_miss_count_stat
6 个来计算命中率（命中 /（命中 + 失败）），基本能够反映命中率
ps：cacti，在用 php 写 script/command 的时候，echo 输出结果必须一次性输出，否则 cacti 无法接收到结果，比如 echo “a:”.”20 “;echo “b:”.”30″; 只能接收到 a 的值，必须 echo “a:”.”20 “.”b:”.”30″; 才可以，但在 cli 里输出是一样的。这点问题折腾了 1 个上午。

cacti 建立模板和输入就大概写个流程，就不仔细写了
1、Data Input Methods，记得选择 script/command 就可以了，Input String 里对照程序来写比如：
<path_php_binary> -q <path_cacti>/scripts/flashapp_get_ts_stat.php completed_requests <host_ip>

记得填对应的需求就好了，下面的 Output fields，大家根据输出来写吧
2、Data Templates
自己起名字了，什么的。不会看前面的文章，注意下面的 Data Source Type 选择就好了
3、Graph Templates
这部分大家根据喜好自己设置吧。
ps 附件 cacti 模板和 php,php 放到 scripts 目录,xml 导入就好了
