併發連接數和響應時間抓取想法
1.數據圖使用cacti for nginx插件進行記錄
2.nginx編譯stub_status模塊，log記錄添加[$time_local]和$request_time字段
3.併發連接數定期curl status頁面獲得
4.響應時間使用本地時間戳做條件在日誌中匹配得到（未改造nginx記錄日期格式）
本地抓取shell笨拙基礎版
1.根據時間戳抓取響應時間和併發連接數做join
2.nginxstatus current顯示當前的併發連接數，響應時間，一秒鐘內的響應時間均值和最大值nginxstatus 3.detail顯示過去24小時內的每一分鐘內的併發連接數和響應時間均值
4.nginxstatus crond每秒鐘記錄一次併發連接數
5.nginxstatus help
