JMeter配电负载测试错误：连接拒绝主机

Question

我们在JMeter远程测试中面临问题。Master被困在：

正在端口4445上等待可能的Shutdown/StopTestNow/Heapdump消息

当客户抛出时：

连接被拒绝到主机异常

我们正在运行如下大师：

.\jmeter  <b>-Djava.rmi.server.hostname=10.19.120.43 </b> -n -t .\Test.jmx -R 10.75.225.188

但是在从属端测试完成状态被发送到其他一些IP地址：

仅供参考：这台机器上运行了docker，并且10.0.75.1与它相关联

Answer 1

您需要在 Dockerfile（或使用主机网络驱动程序）和 10.75.225.188 计算机的防火墙中公开端口 1099（或用作server_port的任何端口），这是 JMeter 主计算机可以与从属计算机建立连接的最低要求。
