使用 JMeter 收集 Perfmon 示例 Java API

Question

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

我知道如何使用 this 方法收集基本的汇总结果，但我找不到任何与使用 Java API

的服务器性能监控相关的信息

如有任何帮助，我们将不胜感激。

谢谢

您可以从 Java 代码初始化 PerfMon Metrics Collector 侦听器，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());
