通过 Jmeter 从 Phantomjs 收集客户端性能指标

问题描述

在整个PhantonJS Driver Config中，我们有没有什么办法可以通过phantomjs通过使用Jmeter DomLoad windLoad ResourceCount Resource size来捕获以下客户端性能指标.

谢谢

解决方案

我建议使用允许执行任意 JavaScript 代码的 WDS.browser.executeScript() 方法捕获指标.完成后，您可以直接将有趣"的值存储到 JMeter 变量中以备后用.

以下是使用

Throughout PhantonJS Driver Config is there any way we can capture the following client-side performance metrics through phantomjs by using Jmeter DomLoad windLoad ResourceCount Resource size.

Thanks

解决方案

I would recommend capturing the metrics using WDS.browser.executeScript() method which allows executing arbitrary JavaScript code. Once done you can directly store "interesting" values into JMeter Variables for later use.

Here is an example of using Navigation API to get extended information on page loading:

WDS.sampleResult.sampleStart()
WDS.browser.get('http://jmeter-plugins.org')
var timings = WDS.browser.executeScript('var performance = window.performance || window.webkitPerformance || window.mozPerformance || window.msPerformance || {}; var timings = performance.timing || {}; return timings;');
WDS.log.info(timings)
WDS.sampleResult.sampleEnd()
