用于SampleResult.subResult的Jmeter Graph Listener

问题描述

我正在寻找将输出SamplerRequest对象的子结果的jmeter图形侦听器。我还没有找到一个，我非常渴望得到它。

解决方案

老问题，我知道。

不幸的是，没有JMeter图形侦听器将绘制附加到SampleResult的子结果的结果。刚刚面对同样的问题，我选择自己写。

步骤：

1. 将下面的类作为jar编译。


2. 将jar放入jMeter的lib / ext文件夹中。打开您的测试计划，浏览菜单以正常添加监听器，选择SubResult Distributed Response Graph。
   
3. 运行您的测试计划。
   

类：

下面的类将提供一个响应时间分布图，它只能显示子结果。

  public class SubResultDistributedResponseTimeListener extends DistributionGraphVisualizer {
 
 private static final Logger LOG = LoggingManager.getLoggerForClass（）; 
 
 @Override 
 public void add（final SampleResult res）{
 final List< SampleResult> subResults = Arrays.asList（res.getSubResults（））; 
 final SubResultDistributedResponseTimeListener inst = this; 
 
（SampleResult r：subResults）{
 long time = r.getEndTime（）{
 public void run（）{
 ） -  r.getStartTime（）; 
 LOG.info（Adding result; start：+ r.getStartTime（）+end：+ r.getEndTime（）+duration：+ time）; 
 SamplingStatCalculator model = inst.getCustomModel（）; 
 if（model！= null）{
 model.addSample（r）; 
 inst.updateGui（model.getCurrentSample（））; 
} 
} 
} 
}）; 
 
} 
 
 //我们需要这个，因为DistributionGraphVisualizer有一个私有字段'模型'，其中
 //处理更新屏幕。小心
 //访问私有字段的SecurityManager问题。 
 public SamplingStatCalculator getCustomModel（）{
 try {
 Field f = DistributionGraphVisualizer.class.getDeclaredField（model）; 
 f.setAccessible（true）; 
 return（SamplingStatCalculator）f.get（this）; 
} catch（NoSuchFieldException e）{
 e.printStackTrace（）; 
} catch（SecurityException e）{
 e.printStackTrace（）; 
} catch（IllegalArgumentException e）{
 e.printStackTrace（）; 
} catch（IllegalAccessException e）{
 e.printStackTrace（）; 
} 
返回null; 
} 
 
 @Override 
 public String getName（）{
 returnSubResult Distributed Response Graph; 
} 
 
 @Override 
 public String getStaticLabel（）{
 return this.getName（）; 
} 
 
 @Override 
 public String getLabelResource（）{//将此侦听器名称添加到右键单击上下文菜单。 
返回this.getName（）; 
} 
  

注意，这个丑陋的catch块是因为我必须在Java 1.5中编译。

我会让读者根据需要扩展不同的图形监听器。

I am looking for a jmeter graph listener that will output the subresults of a SamplerRequest object. I haven't found one yet and I'm very keen on getting it.

解决方案

Old question, I know.

Unfortunately, it appears that there are no JMeter graph listeners that will graph the results of sub results attached to a SampleResult. Having just been faced with the same problem, I chose to write my own.

Steps:

1. Compile the below class as a jar.
2. Place the jar in jMeter's lib/ext folder.
3. Open your test plan, navigate through the menu's to add a Listener as normal, selecting "SubResult Distributed Response Graph"
4. Run your test plan.

Classes:

The below class will provide a Response Time Distribution graph, that will only graph Sub Results.

public class SubResultDistributedResponseTimeListener extends DistributionGraphVisualizer {

private static final Logger LOG = LoggingManager.getLoggerForClass();

@Override
public void add(final SampleResult res) {
    final List<SampleResult> subResults = Arrays.asList(res.getSubResults());
    final SubResultDistributedResponseTimeListener inst = this;

    JMeterUtils.runSafe(new Runnable() {
        public void run() {
            for (SampleResult r : subResults) {
                long time = r.getEndTime() - r.getStartTime();
                LOG.info("Adding result; start: " + r.getStartTime() + " end: " + r.getEndTime() + " duration: " + time);
                SamplingStatCalculator model = inst.getCustomModel();
                if (model != null) {
                    model.addSample(r);
                    inst.updateGui(model.getCurrentSample());
                }
            }
        }
    });

}

// we need this because DistributionGraphVisualizer has a private field 'model' which
// deals with updating the screen. Watch out for SecurityManager problems with 
// accessing private fields.
public SamplingStatCalculator getCustomModel() {
    try {
        Field f = DistributionGraphVisualizer.class.getDeclaredField("model");
        f.setAccessible(true);
        return (SamplingStatCalculator) f.get(this);
    } catch (NoSuchFieldException e) {
        e.printStackTrace();
    } catch (SecurityException e) {
        e.printStackTrace();
    }  catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }
    return null;
}

@Override
public String getName() {
    return "SubResult Distributed Response Graph";
}

@Override
public String getStaticLabel() {
    return this.getName();
}

@Override
public String getLabelResource() { // add this Listeners name to the right click context menu.
    return this.getName();
}

NB, the horrendously ugly catch block was because I had to compile in Java 1.5.

I'll leave it to the reader to extend different graph listeners should they wish.
