java - JMeter负载测试: ClassNotFoundException: com. blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup

Question

我正在尝试非 GUI 和分布式 JMeter 负载测试。

在发布之前，我在本地进行了测试。我在笔记本电脑上安装了 JMeter，并设置了针对被测系统的测试计划。我安装了插件管理器并安装了并发线程插件。我发现我的 JMX 文件正确且有效，因此我决定推出分布式设置。

我设置了三台机器来生成负载:load-1、load-2 和 load-3。我安装 JMeter 如下: apt update ; apt upgrade在他们所有人身上 apt install jmeter在他们所有人身上将位于我笔记本电脑的/usr/share/jmeter/lib/ext 中的 JAR 复制到所有这些 JAR 的同一目录中:

jmeter-plugins-casutg-2.1.jar
jmeter-plugins-cmn-jmeter-0.3.jar
jmeter-plugins-manager-0.11.jar

我在其中两个上启动了 JMeter 服务器，如下所示:

export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.21
export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.22

我使用第三个来开始分布式测试，如下所示:

jmeter -n -t ~/JMeter_API_TestPlan.jmx -R207.112.137.21,207.112.137.22

分布式设置似乎正确启动，但线程启动失败可能是因为找不到类:

java.lang.ClassNotFoundException:com.blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup(无安全管理器:禁用 RMI 类加载器)

我缺少 JAR 或配置参数吗？

Answer 1

1. jmeter-plugins-cmn-jmeter-0.3.jar 应该转到“lib”文件夹，而不是“lib/ext”
2. 您使用的是 3 年以上的 JMeter 2.11，我建议升级到 JMeter 3.2 (或更高版本)通过从 JMeter downloads page 手动下载它。 Ubuntu 存储库似乎包含非常过时的 JMeter 版本
3. 为了避免插件手动安装出现任何问题，我建议使用 JMeter Plugins Manager 在主主机和所有从属主机上安装相同的插件集。
