使用 JMeter Java API 收集 Perfmon 示例

Question

是否可以使用 Perfmon (jmeter-plugins-perfmon) 通过 JMeter Java API 收集服务器性能？

我知道如何使用this 方法收集基本摘要结果，但我找不到任何与使用 Java API 进行服务器性能监控相关的内容

感谢您对此提供任何帮助。

谢谢

您可以从 Java 代码中初始化PerfMon Metrics Collector 监听器，如下所示：

PerfMonCollector perfMonCollector = new PerfMonCollector();
perfMonCollector.setName("PerfMon Metrics Collector");
perfMonCollector.setProperty("filename","perfmon.jtl");
CollectionProperty metricConnections = new CollectionProperty();
metricConnections.setName("metricConnections");
CollectionProperty cpu = new CollectionProperty();
cpu.setName("cpu");
cpu.addProperty(new StringProperty("host","localhost"));
cpu.addProperty(new StringProperty("port","4444"));
cpu.addProperty(new StringProperty("metric","CPU"));
cpu.addProperty(new StringProperty("metricParam",""));
metricConnections.addProperty(cpu);
perfMonCollector.setProperty(metricConnections);
perfMonCollector.setProperty(TestElement.TEST_CLASS, PerfMonCollector.class.getName());
perfMonCollector.setProperty(TestElement.GUI_CLASS, PerfMonGui.class.getName());
