在 Apache JMeter 中配置响应超时 [英] Configuring response timeout in Apache JMeter

问题描述

我正在尝试检查特定 HTTP 请求的响应时间是否超过 30 秒，如果超过，则将其标记为失败并停止线程.有时我会看到响应时间接近 80 秒，没有浏览器在等待来自服务器的响应那么长时间.

我发现了以下三种在 JMeter 中设置超时值的方法，但是这让我很困惑，因为有多种选择，我不知道该使用哪一种，或者它们之间是否有任何区别.

以下是我发现的与响应超时相关的选项:

1. 在采样器中设置响应超时值
2. 添加持续时间断言

3. 在jmeter.properties 配置文件中设置超时.我在这里找到的选项:

1. os_sampler.poll_for_timeout=x
2. http.socket.timeout=x
3. httpclient.timeout=x

所以，问题是我不知道从列出的选项中设置响应超时的位置.这些选项之间有什么区别吗?所以我希望看到的结果是:如果特定 HTTP 请求需要超过 30 秒才能从服务器获得响应，请停止等待响应并将其标记为失败请求.

解决方案

根据您的需要，断言不是正确的解决方案，因为它只会将请求标记为失败但会等待.

正确的选项是响应超时.

关于第三点

1. os_sampler.poll_for_timeout=x => 不适用于 http，请参阅:

     I am trying to check if a particular HTTP request's response time is over 30 seconds, and if it is, then mark it as failed and stop the thread. Sometimes I can see response times close to 80 seconds, an no browser is waiting that long for a response from the server.

     I found the following three ways to set a timeout value in JMeter, however this confuses me, because there is multiple options and I don't know which one to use, or if there is any difference at all between them.

     So here are the options I found that are related to response timeout:

     1. Setting Response timeout value in the sampler
     2. Add a Duration assertion

     
     3. Setting timeout in jmeter.properties configuration file. Options I found here:

     1. os_sampler.poll_for_timeout=x
     2. http.socket.timeout=x
     3. httpclient.timeout=x

     So, the problem is that I don't know where to set the response timeout from the listed options. Is there any difference at all between these options? So what I would like to see as a result: If a particular HTTP request takes more than 30 seconds to get a response from the server, stop waiting for a response and mark it as a failed request.

     解决方案

     For your need, an assertion is not the right solution as it will only mark the request as failed but it will wait.

     The right option is a response timeout.

     Regarding the 3rd point

     1. os_sampler.poll_for_timeout=x => not for http, see:

        • https://github.com/apache/jmeter/blob/master/bin/jmeter.properties

     2. http.socket.timeout=x => applies to all requests using HttpClient4 or 3, see:

        • https://github.com/apache/jmeter/blob/master/bin/hc.parameters

     3. httpclient.timeout=x => Same, see:

        • https://github.com/apache/jmeter/blob/master/bin/jmeter.properties

     I think the best option is to use 1. , if you want those values to apply to all requests, just use Http Request Defaults element:
