JMeter - 如何记录失败响应的完整请求？

发布于 2024-08-06 19:59:05 字数 2459 浏览 3 评论 0原文

我正在使用 JMeter 命令行对我们的网站 api 进行压力测试。现在，这是我返回的示例结果：

Creating summariser <summary>
Created the tree successfully using street_advisor.jmx
Starting the test @ Sat Oct 03 15:22:59 PDT 2009 (1254608579848)
Waiting for possible shutdown message on port 4445
summary +     1 in   0.0s =   37.0/s Avg:    27 Min:    27 Max:    27 Err:     1 (100.00%)
<snip a few more lines>
<then i break it>

所以我收到错误。

目前，所有错误都将保存到文件中。当我检查该文件时，它说它是 404。呃..好吧。无论如何，我可以确切看到请求 JMeter 尝试了什么吗？

这是我的配置文件的片段...

<ResultCollector guiclass="SimpleDataWriter" testclass="ResultCollector" testname="Error Writer" enabled="true">
          <boolProp name="ResultCollector.error_logging">true</boolProp>
          <objProp>
            <name>saveConfig</name>
            <value class="SampleSaveConfiguration">
              <time>true</time>
              <latency>true</latency>
              <timestamp>false</timestamp>
              <success>true</success>
              <label>true</label>
              <code>true</code>
              <message>true</message>
              <threadName>false</threadName>
              <dataType>true</dataType>
              <encoding>false</encoding>
              <assertions>true</assertions>
              <subresults>true</subresults>
              <responseData>false</responseData>
              <samplerData>false</samplerData>
              <xml>true</xml>
              <fieldNames>false</fieldNames>
              <responseHeaders>true</responseHeaders>
              <requestHeaders>true</requestHeaders>
              <responseDataOnError>false</responseDataOnError>
              <saveAssertionResultsFailureMessage>false</saveAssertionResultsFailureMessage>
              <assertionsResultsToSave>0</assertionsResultsToSave>
              <bytes>true</bytes>
            </value>
          </objProp>
          <stringProp name="filename">./error.jtl</stringProp>
        </ResultCollector>

现在，在有人说“检查网络服务器日志文件”之前，我知道我可以做到这一点，是的，我找到了 404 ..但我希望看看是否可能无需访问它们..特别是如果它们位于另一台服务器上和/或我无法访问它们。请帮忙！

i'm using JMeter command line to stress test our website api. Now, here's a sample result i'm getting back:

Creating summariser <summary>
Created the tree successfully using street_advisor.jmx
Starting the test @ Sat Oct 03 15:22:59 PDT 2009 (1254608579848)
Waiting for possible shutdown message on port 4445
summary +     1 in   0.0s =   37.0/s Avg:    27 Min:    27 Max:    27 Err:     1 (100.00%)
<snip a few more lines>
<then i break it>

So i'm getting an error.

Currently, all errors are going to a file. When i check that file, it's saying it's a 404. Er.. ok. Is there anyway i can see exactly what the request JMeter tried?

here's a snippet of my config file...

<ResultCollector guiclass="SimpleDataWriter" testclass="ResultCollector" testname="Error Writer" enabled="true">
          <boolProp name="ResultCollector.error_logging">true</boolProp>
          <objProp>
            <name>saveConfig</name>
            <value class="SampleSaveConfiguration">
              <time>true</time>
              <latency>true</latency>
              <timestamp>false</timestamp>
              <success>true</success>
              <label>true</label>
              <code>true</code>
              <message>true</message>
              <threadName>false</threadName>
              <dataType>true</dataType>
              <encoding>false</encoding>
              <assertions>true</assertions>
              <subresults>true</subresults>
              <responseData>false</responseData>
              <samplerData>false</samplerData>
              <xml>true</xml>
              <fieldNames>false</fieldNames>
              <responseHeaders>true</responseHeaders>
              <requestHeaders>true</requestHeaders>
              <responseDataOnError>false</responseDataOnError>
              <saveAssertionResultsFailureMessage>false</saveAssertionResultsFailureMessage>
              <assertionsResultsToSave>0</assertionsResultsToSave>
              <bytes>true</bytes>
            </value>
          </objProp>
          <stringProp name="filename">./error.jtl</stringProp>
        </ResultCollector>

Now, before someone says 'Check the webserver log files', I know I can do this and yep, I've found the 404 .. but i'm hoping to see if it's possible without accessing them .. especially if they are on another server and/or I can't get access to them.
Please help!

查看结果树组件显示所有结果的树示例响应，允许您查看任何示例的请求和响应。

负载测试时（始终处于非 GUI 模式），填写“文件名”字段并选择仅保存错误响应：

正如您在上面看到的，我们单击了“配置”选择除 CSV 字段之外的所有字段。

您还可以使用将响应保存到文件将整个响应保存到文件中：

我发现此线程正在寻找一种解决方案，仅在采样器失败时记录响应，因此接受的解决方案对我来说并不好。我在涉及数十万个样本的非常高的负载下偶尔会出现样本失败，因此树侦听器对我来说完全不切实际（它将达到几千兆字节的大小），所以这就是我想出的（这应该对我有用） OP 的场景也是如此）：

添加一个 [JSR223 Assertion][1] （应该在所有其他断言之后）并将以下代码放入其中：

if (Boolean.valueOf(vars.get("DEBUG"))) {
  for (a: SampleResult.getAssertionResults()) {
    if (a.isError() || a.isFailure()) {
      log.error(Thread.currentThread().getName()+": "+SampleLabel+": Assertion failed for response: " + new String((byte[]) ResponseData));
    }
  }
}

这将导致整个响应被记录到jmeter 日志文件在我的情况下很好，因为我知道响应非常小，但对于大响应，可以进行更智能的处理。

I found this thread searching for a solution to log the response only when a sampler fails, so the accepted solution is not good for me. I have occasional sample failures at a very high load involving hundreds of thousands of samples, so a tree listener is completely impractical for me (it will reach several gigabytes in size), so here is what I came up with (which should be good for the OP's scenario as well):

Add a [JSR223 Assertion][1] (should come after all the other assertions) and put the below code in it:

if (Boolean.valueOf(vars.get("DEBUG"))) {
  for (a: SampleResult.getAssertionResults()) {
    if (a.isError() || a.isFailure()) {
      log.error(Thread.currentThread().getName()+": "+SampleLabel+": Assertion failed for response: " + new String((byte[]) ResponseData));
    }
  }
}

This will cause the entire response getting logged to the jmeter log file which is fine in my case, as I know that the responses are really small, but for large responses, more intelligent processing could be done.

有一个“将响应保存到文件”侦听器，仅当发生错误时才可以将响应保存到文件。

这就是我记录失败请求的完整请求（请求 URL + 请求正文）的方式。

在线程组中添加监听器

<前><代码>尝试{
var 消息 = "";
var currentUrl = Sampler.getUrl();
消息+=“.URL=”+currentUrl;
var requestBody = Sampler.getArguments().getArgument(0).getValue();
消息+=“--data”+sampler.getArguments();
if(!sampleResult.isSuccessful()){
日志.错误（消息）；
}
}捕获（错误）{
//什么都不做。这可能是一个调试采样器。无需记录错误
}

对于线程组内的每个 Sampler，Listener 将在 Sampler 之后执行此代码。

This is how I log the full request (request URL + request body) for failed requests.

Add a Listener inside the Thread Group

try{
  var message = "";
  var currentUrl = sampler.getUrl();
  message +=  ". URL = " +currentUrl;
  var requestBody = sampler.getArguments().getArgument(0).getValue();
  message += " --data " + sampler.getArguments();

  if(!sampleResult.isSuccessful()){
      log.error(message);
  }

}catch(err){
  //do nothing. this could be a debug sampler. no need to log the error
}

For every Sampler inside the Thread Group, the Listener will execute this code after the Sampler.

我将 BeanShell PostProcessor 添加到最顶层并具有以下代码：

if (!ctx.getPreviousResult().isSuccessful()){
    String httpResponseBody = new String(ctx.getPreviousResult().getResponseData());
    log.error(httpResponseBody);
}

I added a BeanShell PostProcessor to very top level and have this code:

if (!ctx.getPreviousResult().isSuccessful()){
    String httpResponseBody = new String(ctx.getPreviousResult().getResponseData());
    log.error(httpResponseBody);
}
