java - org.apache.http.NoHttpResponseException：服务器地址：80 未能响应 - JMeter

问题描述

我正在 Web 应用程序上使用 Jmeter 5.2 运行负载测试。当我运行线程组时，即使线程数超过 500，我也会做一些配置 jmeter：在 user.properties 中我设置了：httpclient4.retrycount=1

hc.parameters.file=hc.parameters

在 hc.parameters 我设置了：

http.connection.stalecheck$Boolean=true

并在 Http 请求中：客户端实现 > httpClient4

解决方案

很可能您的应用程序过载，因此它无法处理 500 个并发连接，您需要检查以下内容：

  1. 您的应用程序服务器配置，即增加最大传入连接数
  2. 您在 CPU、RAM、可用网络套接字等方面的后端健康状况，可以使用JMeter PerfMon 插件来完成
  3. 您的应用程序配置（连接池、数据库配置等），因为它可能没有针对高负载进行适当调整
