在cacti中使用ATS的stats_over_http模塊進行監控部分性能

最近要監控ATS，使用stats_over_http.so模塊可以使用url來查看ats的狀態，在cacti裏面加上了幾個值來監控，包含：

proxy.process.http.completed_requests

所有收到請求，使用count模式統計每秒完成的請求

proxy.process.http.incoming_requests

proxy.process.http.outgoing_requests

進入和出的請求，基本能夠描述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

給客戶端返回的HTTP status code的數量，基本反映服務情況

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個來計算命中率（命中/（命中+失敗）），基本能夠反映命中率

ps：cacti，在用php寫script/command的時候，echo輸出結果必須一次性輸出，否則cacti無法接收到結果，比如 echo "a:"."20 ";echo "b:"."30";只能接收到a的值，必須 echo "a:"."20 "."b:"."30";纔可以，但在cli裏輸出是一樣的。這點問題折騰了1個上午。

cacti建立模板和輸入就大概寫個流程，就不仔細寫了

1、Data Input Methods，記得選擇script/command 就可以了，Input String裏對照程序來寫比如：

<path_php_binary> -q <path_cacti>/scripts/flashapp_get_ts_stat.php completed_requests <host_ip>

記得填對應的需求就好了，下面的Output fields，大家根據輸出來寫吧

2、Data Templates

自己起名字了，什麼的。不會看前面的文章，注意下面的Data Source Type 選擇就好了

3、Graph Templates

這部分 大家根據喜好自己設置吧。

ps附件 cacti模板和php,php放到scripts目錄,xml導入就好了
