ngrinder工作原理：這里的controller就是ngrinder平台

部署（以windows為例）：

把下載下來的ngrinder-controller.war重命名為ngrinder.war放到tomcat下面，啟動tomcat

啟動完瀏覽器訪問：http://localhost:8080/ngrinder

默認用戶名admin，密碼admin，選擇中文

登錄成功后下載agent和monitor

解壓並啟動agent

在機器足夠的情況下，應該把agent單獨部到一台機器上，由於機器有限這里和ngrinder部到同一台機器

先編輯配置文件：__agent.conf，修改ngrinder所在的ip和端口號（默認端口號16001）

雙擊啟動文件，下面這樣就算啟動成功了

把前面下載的monitor上傳至服務器，並解壓

進入到該目錄，里面的東西和agent一樣

啟動，這里第一次報錯，說沒有找到本機路由，后來查看，是因為當前host里面沒有配置當前使用的這個ip

改host文件

再次啟動，成功

回到ngrinder，編寫腳本

這里對java和python哪個熟一點就選哪個

先確認接口是通的：http://192.168.1.163:8080/PerfTeach/TimeMonitor?id=1

Groovy（java版）：

點創建后會生成如下代碼：

點驗證腳本，在控制台最下面有日志，可以看到通不通過
