部署demo

在機器上部署本身的用於測試的demo，我就是直接在tomcat下安裝的

寫腳本

經過書寫grovy腳本訪問本身的demo。
將寫好的grovy腳本上傳拿到ngrinder

壓力測試

腳本：指向剛纔的腳本，經過這個腳本不斷的去訪問本身的demo
目標主機：即本身剛纔部署的demo的機器ip
如此便關聯起來了

目標主機監控

在目標主機上一樣須要一個監控的腳本
最後生成監控的日誌
具體腳本是機密。

可能報錯

運行壓力測試的時候報錯如上，Connection refused，就是個人tomcat長時間沒有動它，本身掛掉了，因此Connection refused，鬱悶。

總結：

ngrinder的做用就是主要用來不斷的發送請求的（搭配上腳本效果更好），固然在最後測試完成的時候也會有監控的信息，可是粒度比較粗，也能知足需求，而咱們目標主機上的腳本就是專門用來監控請求時候的主機cpu 等信息的，固然數據庫的主機也能夠來一份監控腳本，作一個輔助的判斷功能。
