elasticsearch - 尝试在 JMeter 和 Kibana 之间进行集成时出错

Question

我正在尝试使用本手册将 Jmeter 连接到 Kibana： https ://blogs.sap.com/2016/04/06/load-testing-with-jmeter-test-results-visualization-using-kibana-dashboards/comment- page-1/#comment-398399

• 我正在使用 JMeter 3.2，并下载了 elasticsearch-5.6.4.zip。

• 我提取 zip 并将文件夹 elasticsearch-5.6.4 放在 C:\Jmeter\apache-jmeter-3.2\lib

• 我下载了jar JMeter_ElasticsearchListener.jar 并把它放在 C:\Jmeter\apache-jmeter-3.2\lib\ext

• 我重新启动 JMeter 并按下 add -> listener -> backend listener 并得到这些错误：

Answer 1

我不认为 JMeter 会递归地搜索其“lib”文件夹中的任何文件夹来寻找它可以添加到其类路径中的任何 .jar，因此我建议将所有 .jar 从elasticsearch-5.6.4文件夹移动到 JMeter 的“lib”文件夹。

或者，您可以将下一行添加到user.properties文件（位于 JMeter 安装的“bin”文件夹下）

user.classpath=C:\Jmeter\apache-jmeter-3.2\lib\elasticsearch-5.6.4`

在这两种情况下，都需要重新启动 JMeter 才能获取库。

Answer 2

您缺少一个 jar，即 REST 客户端 jar，只需将以下 jar 添加到您的 lib 文件夹（C:\Jmeter\apache-jmeter-3.2\lib）

elasticsearch-rest-client-5.6.4.jar
