使用locust 做性能測(cè)試
pip install locust -i https://pypi.tuna.tsinghua.edu.cn/simple

from locust umport HttpUser, task, between

#創(chuàng)建一個(gè)類，從HTTPUser繼承

class CarRental(HttpUser):
#思考時(shí)間，between是locust中的一個(gè)方法，在1~3s之間取隨機(jī)數(shù)
wait_time = between(1,3)
# task 帶參數(shù)，表示任務(wù)的權(quán)重，默認(rèn)是1
# 訪問車輛的頁(yè)面，比訪問Menu頁(yè)面的人數(shù)多，或者訪問的頻率高
@task(3)
def loadAllCar(self):
      ret = self.client.get("/carRental/car/loadAllCar.action?page=1&limit=10")
      assert ret.status_code == 200

def loadAllMenu(self):
      ret = self.client.get("/carRental/menu/loadAllMenu.action?page=1&limit=10")
      assert ret.status_code == 200

# 命令行中執(zhí)行
# locust回啟動(dòng)一個(gè)web服務(wù)，使用8089端口
# 如果端口被占用加上這個(gè)參數(shù)修改端口號(hào) --web-port=8088

Jmeter中Perf插件可以配合ServerAgent來監(jiān)控服務(wù)器。
Locust無法監(jiān)控服務(wù)器。可以使用其他的監(jiān)控工具來監(jiān)控。
用python代碼實(shí)現(xiàn)一段腳本，來監(jiān)控服務(wù)器。
psutil中提供一些方法，獲取服務(wù)器的數(shù)據(jù)
