Question

我已在其中一台远程 AWS 服务器上安装了 jmeter 5.2.1。

我想收集响应和服务器信息以及性能指标的摘要报告。

我已下载 jmeter-plugins-manager-1.6.jar 和 jmeter-plugins-perfmon-2.1.jar 并复制到 /lib/ext

然后我从本地机器上的 jmeter 创建了一个测试脚本并复制到服务器并尝试运行相同的 jmeter -n -t AWS.jmx -l awsresults.jtl

但我收到一个错误：

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/root/apache-jmeter-5.2.1/bin/AWS.jmx'. 
Cause:
ClassNotFoundException: kg.apc.jmeter.vizualizers.CorrectedResultCollector

line number         : 219
version             : 5.2.1

当我在 jmeter 的本地机器上运行它时，它按预期工作。

有人可以帮助我理解并解决错误吗？

该错误意味着您的 AWS 实例上没有安装 PerfMon 插件，我认为当前版本的 JMeter 插件管理器无法在非 GUI 模式下检测/安装缺少的插件，因此您需要手动执行此操作。

类似于：

下载JMeter Plugins Manager：

wget https://jmeter-plugins.org/get/ -O /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar

下载JMeter Plugins Command Line Runner

wget https://repo1.maven.org/maven2/kg/apc/cmdrunner/2.2/cmdrunner-2.2.jar -P /opt/apache-jmeter-5.2.1/lib/

安装JMeter Plugins Manager Command Line Utility：

java -cp /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar org.jmeterplugins.repository.PluginManagerCMDInstaller

安装 PerfMon Plugin：

/opt/apache-jmeter-5.2.1/bin/./PluginsManagerCMD.sh install jpgc-perfmon

就是这样，现在您应该可以执行测试了

附言According to JMeter Best Practices you should always be using the latest version of JMeter 所以考虑升级到 JMeter 5.4.1 或任何它的 current JMeter latest stable version

如何在非 GUI 模式下在远程服务器上安装插件管理器和性能指标收集器？
