Jmeter 测试计划在本地模式（单节点）下工作，但在分布式模式下不工作

Question

我在 k8s 上部署了我的 JMeter 设置，带有一个主 pod 和几个从属 pod。如果我尝试在不使用远程实例 (-R) 的情况下运行此测试，则它可以正常工作，但使用远程实例，它会在没有任何执行的情况下完成。我没有收到任何错误。

即使不使用 -R 选项，它也可以在从节点上工作。我尝试了一个从节点，只是为了确保我的从节点能够执行它并且设置没有问题。

jmeter -Jserver.rmi.ssl.disable=true -n -t /tests/jmeter/GGSPerf_testplan.jmx -j jmeter_tests.log
jmeter -Jserver.rmi.ssl.disable=true -n -t /tests/jmeter/GGSPerf_testplan.jmx -j jmeter_tests.log -R 
XX.XX.XX.XX

但是这个测试计划是有效的：https://github.com/kaarolch/kubernetes-jmeter/blob/master/examples/simple_test.jmx

Answer 1

我可以看到至少一个失败的原因：您的测试计划不是valid XML file，因为它在底部缺少这两行：

    </hashTree>
</jmeterTestPlan>

此外，如果您在主设备端禁用安全 RMI，您应该对所有从设备执行相同操作：

jmeter-server -Jserver.rmi.ssl.disable=true

最后，注意 JMeter slave 的 IP 地址，当你启动 JMeter slave 时，你应该会看到如下内容：

创建的远程对象：UnicastServerRef2 [liveRef: [endpoint:XX.XX.XX.XX:1794,objID:[38be521f:16d80bfab94:-7fff, 2395028286451043349]]]

如果 IP 地址不是您所期望的，即运行 JMeter slave 的机器有多个网络接口，您可以通过 java.rmi.server.hostname 属性明确指定要绑定的一个，例如：

jmeter-server -Jserver.rmi.ssl.disable=true -Djava.rmi.server.hostname=XX.XX.XX.XX
