如何在JMeter中测量多个http采样器的响应数据的大小。我需要在加载过程中找到所有http采样器的单独大小，而不是整体大小。我使用Beanshell采样器，但它给出的是整体大小，而不是每个采样器的单独大小。

import java.util.io.*;
import java.lang.io.*;
test = prev.getResponseDataAsString().length();
text = ctx.getCurrentSampler().getName();
log.info("Sampler Name: " +text+ ": Size: " +test);
if(text.equalsIgnoreCase("Test Sampler"))
{
 props.put("totalsize",Integer.parseInt("0"));
}
else
{
  props.put("totalsize", (props.get("totalsize")!=null?props.get("totalsize"):0) + test);
}
log.info("totalsize is = "+props.get("totalsize"));

I am using Beanshell sampler but it is giving overall size not individual for each sampler.
I need total individual response size for each sampler during my load test.
