在Cacti中使用ATS的stats_over_http模块进行监控部分性能

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
